Intercontinental disjunctions are one of the most attractive and interesting biogeographical patterns. Bryophytes often exhibit such distributions, which is partly explained by their great ability to disperse over long distances. However, such intercontinental ranges are sometimes a distorted reality caused by the existence of unnoticed species. This study investigates whether the disjunction between East Africa and southern India of the moss Lewinskya firma reflects the genuine distribution of a single species or implies pseudo-cryptic species (whose morphological differentiation is subtle and have therefore been masked). An integrative taxonomic approach combining morphological and molecular methods (genotyping by sequencing, GBS) was used, based on a representation of samples specifically collected from all the major mountainous regions where this moss occurs. Two species, L. firma s. str. and L. afroindica sp. nov. are involved, whose ranges completely overlap in East Africa, although genetic distance and morphological differences in leaf apex shape, vaginula hairs shape and papillosity, spore ornamentation and peristome constitution and ornamentation allow distinguishing both. In addition, the range of L. afroindica extends into both southern Africa and southern India. The phylogenetic reconstruction obtained shows a certain degree of differentiation of the Indian populations, although they are yet morphologically indistinguishable from African populations. The results thus highlight both the existence of overlooked species and the complexity of bryophyte biogeography.
... Macromitrioideae is almost exclusively intertropical, whereas Orthotrichoideae is characteristic of temperate and cold regions of both hemispheres, as well as of high altitudes in tropical mountains. In temperate areas, Orthotrichoideae is one of the main components of the epiphytic communities, both in dry (Draper et al., 2006;Lara et al., 2009) and in oceanic or hyper-oceanic conditions (Garilleti et al., 2015;Lara et al., 2016). ...
... However, most of the extant genera of the subfamily Orthotrichoideae seem to be younger, and apparently, the highest diversification burst of the subfamily took place during the late Eocene and the Oligocene, which is considered to be a period of transition between more tropical to cooler conditions (Zachos et al., 2001;Willis and McElwain, 2002). The genera Ulota, Lewinskya, and Pulvigera probably originated in that period, which is characterized by the regression of humid and warm tropical forests and parallel increase of forested and open habitats with temperate climates (Zachos et al., 2001;Willis and McElwain, 2002), suitable for a relevant proportion of the species of these genera (Draper et al., 2006;Lara et al., 2009). The youngest genus (Pentastichella) would have originated during the Miocene, which is also considered a period of cool and dry climate. ...

Mosses of the subfamily Orthotrichoideae represent one of the main components of the cryptogam epiphytic communities in temperate areas. During the last two decades, this taxonomical group has undergone an extensive revision that has led to its rearrangement at the generic level. However, their phylogenetic relationships and inferences on the evolutionary patterns that have driven the present diversity have little advanced. In this study, we present a dated molecular phylogenetic reconstruction at the subfamily level, including 130 samples that represent the 12 genera currently recognized within the subfamily, and the analysis of four molecular markers: ITS2, rps4, trnG, and trnL-F. We also analyze 13 morphological characters of systematic value to infer their origin and diagnostic utility within the subfamily. The phylogenetic reconstruction yields three main clades within the subfamily, two of which correspond to the tribe Zygodonteae, and one to Orthotricheae. Within Zygodonteae, the genus Zygodon results to be a polyphyletic artificial assembly, and we propose to separate a new genus named Australoria. Conversely, our results do not support the separation of Pentastichella and Pleurorthotrichum at the genus level and we therefore propose to include Pleurorthotrichum in Pentastichella. Regarding Orthotricheae, our analyses clearly allow the distinction of two subtribes: Orthotrichinae and Lewinskyinae. Within the latter, Ulota results a polyphyletic entity, and therefore we propose the segregation of a separate new genus named Atlantichella. Dating analyses allow us to conclude that the split of the tribes within Orthotrichoideae dates from the Middle Jurassic, while the diversification of Orthotrichum and Zygodon probably started during the Late Cretaceous. However, most of the extant genera of this subfamily seem to be younger, and apparently its highest diversification burst took place during the Oligocene. Finally, the analysis of the morphological traits reveals that most of the characters previously used to separate genera and here tested are homoplastic, which has hindered the taxonomical and systematic proposals for decades. However, even if there are no exclusive characters, all of the genera can be defined by the combination of a few characters.
... The genera Nyholmiella Holmen & E.Warncke, Lewinskya F. Lara, Garilleti & Goffinet and Orthotrichum Hedw. represent a group of widely distributed to subcosmopolitan mosses of the family Orthotrichaceae that consists approximately of 167 species (Goffinet et al. 2007, Fedosov & Ignatova 2010, Lara et al. 2007, 2009a, 2009b, Medina et al. 2008, 2012, 2014, Kiebacher & Lüth 2017. They are known to occur throughout the world, except in deserts and wet tropical forests, from the Arctic to the Antarctic, growing mainly epiphytically or epipetrically on boulders and rocks from lowlands up to an elevation of ca 5000 m (Lewinsky 1993). ...
... Hovewer, it can be easily distinguished from that species by its exserted capsules and densely hairy calyptra (Lewinsky 1992, Plášek 2012. Moreover, the exostome teeth in L. speciosa are revolute when dry and touch the capsule only by their tips, whereas in L. affinis they are recurved and usualy appressed against the urn when dry (Lara et al. 2009b Lewinskya speciosa is a panholarctic species having an almost continuous range throughout the arctic, temperate and alpine zones in the Northern Hemisphere (Lewinsky 1992(Lewinsky , 1993. This species has been recorded in North America (Vitt 1973), northern Africa (Lewinsky 1992), and Europe (Lazarenko et al. 1971, Lewinsky 1993, Schäfer-Verwimp & Gruber 2002. ...

Molecular analyses have consistently evidenced the phylogenetic heterogeneity of Orthotrichum Hedw., and suggested the need to segregate the species with superficial stomata in a separate genus. A recent proposal has been made to accommodate the monoicous species with such stomata in the genus Dorcadion Adans. ex Lindb., which is, however, an illegitimate name according to the current Code of nomenclature of algae, fungi and plants. Consequently a new name is required, and the generic name Lewinskya F.Lara, Garilleti & Goffinet is proposed. New combinations are made for all the species included in the new genus. Given the long history of the genus Orthotrichum and the similarities between this genus and Lewinskya, the morphological and geographic circumscriptions of both genera are provided to define them accurately. The taxa remaining in Orthotrichum s.str. are also listed.
... Orthotrichum sprucei is a mainly European species enjoying a temperate climate. It is rather common in the UK and France with a few records in the Iberian Peninsula, Turkey, Kazakhstan and western North America (Lewinsky-Haapasaari and Norris 1998;Goffinet 2002;Lara et al. 2009;Hodgetts and Lockhart 2020;Medina et al. 2020).

Due to the limited knowledge on bryophytes in Algeria, this study aimed to update the Algerian bryophyte flora. Megriss Mountain (also called Jbel or Djebel Megriss), which is a part of the High Plains of Setif, was chosen as a study area for its interesting biological and landscape diversity. The inventory was carried out in different habitats (rocks, trees, soils and streams). Samples were collected from minimum survey areas of 100 cm2 (from soil and rocks), but the sample area was sometimes increased depending on the availability of species; the trees were mostly sampled between heights of 1 and 2 meters. As a result, a preliminary list of 55 moss species were identified, including 44 acrocarpous and 11 pleurocarpous, belonging to 13 families and 29 genera. The most species-rich families were Pottiaceae, Orthotrichaceae, Brachytheciaceae, and Bryaceae, while the most diverse genera were Lewinskya and Syntrichia. Epilithic mosses were dominant, followed by terricolous mosses and finally epiphytic mosses. The most frequent species in the study area were Orthotrichum diaphanum, Lewinskya acuminate, Didymodon insulanus, Grimmia pulvinata, and Tortella squarrosa. The study also highlights the presence of a new species that had never been recorded in Algeria -Orthotrichum scanicum. A comprehensive description, microphotographs of the species are provided and its ecology is also discussed. This discovery will contribute to the enrichment of the Algerian bryophyte flora in general and of the Orthotrichaceae in particular,within the genus Orthotrichum, which now has a total of 11 species recorded in the country.
... Orthotrichum macrocephalum was readily recognized as the samples showed all the diagnostic characteristics stated by Lara et al. (2009) and Lara & Garilleti (2014): small-sized plants, lingulate or lanceolate-lingulate leaves with rounded or obtuse apices and costa ending below the apex, recurved and unistratose margins, pluripapillose and unistratose laminal cells, cylindrical gemmae with 6 to 15 cells. Other morphological characters observed were the emergent capsule with eight longitudinal orange ribs and star-shaped mouth when dry, scarcely constricted below the mouth, immersed stomata in the capsule wall, and very papillose endostome segments (Fig. 3). ...

The bryoflora of the Setifian High Plains, which situated in the Northeastern region of Algeria is poorly known. Megriss Mountain is one of the most important ecosystems in this region. The examination of Orthotrichaceae samples collected during bryophytes diversity investigations in the northern part of Megriss resulted in the identification of the epiphytic species; Orthotrichum macrocephalum F. Lara, Garilleti & Mazimpaka. The identification was made based on its leaves with rounded or obtuse apices, recurved margins, pluripapillose laminal cells, the presence of propagules, emergent capsule with eight longitudinal orange ribs and star-shaped mouth when dry, scarcely constricted below the mouth, immersed stomata in the capsule wall and the papillose endostome segments. This acrocarpous moss with a marked affinity for the Mediterranean climate has never been recorded in the Algerian bryoflora. A comprehensive description, microphotographs, and distribution map in Algeria of this species are provided. Moreover, its ecology is also discussed.
... Bryophyte specimens for the present study were collected from various habitats and substrates at 35 localities of the study area, in different vegetation periods between March 2019 and December 2021 ( Table 1). Localities of bryophyte specimens are given in Fig. 4. Bryophyte specimens were identified using various floras, revisions and monograph studies (Frey & Kürschner 1991;Lewinsky 1993;Zander 1993;Sharp & al. 1994;Frey & al. 1995;Bloom 1996;Paton 1999;Muñoz & Pando 2000;Erdağ & Kürschner 2002;Smith 2004;Cortini Pedrotti 2001Ignatova & Muñoz 2004;Guerra & al. 2006;Brugués & al. 2007;Allen 1994Allen , 2004Allen , 2010Allen , 2018Lara & al. 2009;Erdağ & Kürschner 2009a, 2009bLara & al. 2010;Erdağ & Kürschner 2011;Orgaz & al. 2011Orgaz & al. , 2012Orgaz & al. , 2013Plášek & al. 2015;Lara & al. 2016;Fedosov & al. 2017;Özenoğlu & al. 2019;Kürschner & Frey 2020).

Orthotrichoideae aggregates epiphytic mosses widespread throughout temperate regions and high tropical mountains of the world. Recently, important advances have been made in elucidating its phylogenetic relationships and evolutionary patterns. Fourteen genera are currently recognized within the subfamily, which are spread over two main tribes: Orthotricheae, comprising Orthotrichinae and Lewinskyinae, and Zygodonteae. Despite the progress, some groups have received little attention, as is the case of genus Codonoblepharon. Recent studies have suggested that this genus may represent a separate lineage from Zygodonteae, in which it traditionally has been considered. Although, none of the studies were conclusive as they did not include a representative sampling of the Codonoblepharon species. This work aims to evaluate the taxonomic position of Codonoblepharon and its phylogenetic relationships within Orthotrichoideae. For this purpose, we present an updated phylogenetic tree based on four different loci, one belonging to the nuclear genome (ITS2) and the rest to the plastid genome (rps4, trnG and trnL-F). The phylogenetic reconstruction recovers all samples of Codonoblepharon in a monophyletic group, sister to the rest of the subfamily, constituting a lineage independent of the two currently recognized tribes. For this reason, we propose the new tribe Codonoblepharonteae to accommodate Codonoblepharon.
... Orthotrichoideae is, in turn, divided into two tribes, Orthotricheae Engler and Zygodonteae Engler (Goffinet and Vitt, 1998;Draper et al., 2021). Of these, Orthotricheae stands out as one of the main components of the epiphytic communities in temperate areas, both in dry (Draper et al., 2006;Lara et al., 2009) and in oceanic or hyperoceanic conditions (Garilleti et al., 2015;Lara et al., 2016). Species within Orthotricheae are acrocarpous mosses, whose gametophores grow erect or rarely decumbent and form cushions or tufts. ...

Pimpinella species are annual, biennial, and perennial semibushy aromatic plants cultivated for folk medicine, pharmaceuticals, food, and spices. The karyology and genome size of 17 populations of 16 different Pimpinella species collected from different locations in Iran were analyzed for inter-specific karyotypic and genome size variations. For karyological studies, root tips were squashed and painted with a DAPI solution (1 mg/ml). For flow cytometric measurements, fresh leaves of the standard reference (Solanum lycopersicum cv. Stupick, 2C DNA = 1.96 pg) and the Pimpinella samples were stained with propidium iodide. We identified two ploidy levels: diploid (2x) and tetraploid (4x), as well as five metaphase chromosomal counts of 18, 20, 22, 24, and 40. 2n = 24 is reported for the first time in the Pimpinella genus, and the presence of a B-chromosome is reported for one species. The nuclear DNA content ranged from 2C = 2.48 to 2C = 5.50 pg, along with a wide range of genome sizes between 1212.72 and 2689.50 Mbp. The average monoploid genome size and the average value of 2C DNA/chromosome were not proportional to ploidy. There were considerable positive correlations between 2C DNA and total chromatin length and total chromosomal volume. The present study results enable us to classify the genus Pimpinella with a high degree of morphological variation in Iran. In addition, cytological studies demonstrate karyotypic differences between P. anthriscoides and other species of Pimpinella, which may be utilized as a novel identification key to affiliate into a distinct, new genus – Pseudopimpinella.

Phylogenomic data increase the possibilities of resolving the evolutionary and systematic relationships among taxa. This is especially valuable in groups with few and homoplasious morphological characters, in which systematic and taxonomical delimitations have been traditionally difficult. Such is the case of several lineages within Bryophyta, like Orthotrichaceae, the second most diverse family of mosses. Members of tribe Orthotricheae are common in temperate and cold regions, as well as in high tropical mountains. In extratropical areas, they represent one of the main components of epiphytic communities, both in dry and oceanic or hyperoceanic conditions. The epiphytic environment is considered a hostile one for plant development, mainly due to its low capacity of moisture retention. Thus, the diversification of the Orthotrichaceae in this environment could be seen as striking. Over the last two decades, great taxonomic and systematic progresses have led to a rearrangement at the generic level in this tribe, providing a new framework to link environment to patterns of diversification. Here, we use nuclear loci targeted with the GoFlag 408 enrichment probe set to generate a well-sampled phylogeny with well-supported suprageneric taxa and increasing the phylogenetic resolution within the two recognized subtribes. Specifically, we show that several genera with Ulota-like morphology jointly constitute an independent lineage. Within this lineage, the recently described Atlantichella from Macaronesia and Western Europe appears as the sister group of Ulota bellii from Zealandia. This latter species is here segregated in the new genus Rehubryum. Assessment of the ecological and biogeographical affinities of the species within the phylogenetic framework suggests that niche adaptation (including climate and substrate) may be a key evolutionary driver that shaped the high diversification of Orthotricheae.
... In the past and in the first decade of the present century, Orthotrichum pumilum and O. schimperi were usually treated as a single species (e.g., Corley et al., 1981;Lewinsky-Haapasaari, 1998;Meinunger & Schröder, 2007;Nyholm, 1960;Smith, 2004), although sometimes they were retained as separate species (e.g., Smith, 1978;Szafran, 1961). However, in the past two decades, the distinctness of these two species is increasingly accepted (Cortini Pedrotti & Lara, 2001;Hill et al., 2006;Hodgetts et al., 2020;Lara & Garilleti, 2014;Lara et al., 2009;Ros et al., 2013).

The occurrence of two epiphytic moss species, Orthotrichum alpestre Bruch & Schimp. and O. schimperi Hammar, in the moss flora of Poland is discussed. The former represents an entirely new country record based on a specimen collected from the Polish Eastern Carpathians, whereas the latter is reinstated as a member of the Polish moss flora. The complex and entangled taxonomic and nomenclatural history of O. schimperi is outlined, sources of its confusion are discussed, and two correctly determined specimens from Poland are cited. The two species are briefly characterized and illustrated, and a key to the genera and species of Polish orthotrichaceous mosses is presented.

... A morphological analysis was conducted on the 30 selected specimens to assess the differences between the Californian plants attributed to either O. shevockii or O. kellmanii, and those from Tenerife. A set of morphological characters, both qualitative and quantitative, was selected and studied according to our previous experience with Orthotrichaceae [32,33,[43][44][45]. Qualitative traits of the gametophyte included plant habit and several leaf characters such as leaf shape, leaf margin, lamina bistratosity, and cell papillosity. ...

Biogeography, systematics and taxonomy are complementary scientific disciplines. To understand a species’ origin, migration routes, distribution and evolutionary history, it is first necessary to establish its taxonomic boundaries. Here, we use an integrative approach that takes advantage of complementary disciplines to resolve an intriguing scientific question. Populations of an unknown moss found in the Canary Islands (Tenerife Island) resembled two different Californian endemic species: Orthotrichum shevockii and O. kellmanii. To determine whether this moss belongs to either of these species and, if so, to explain its presence on this distant oceanic island, we combined the evaluation of morphological qualitative characters, statistical morphometric analyses of quantitative traits, and molecular phylogenetic inferences. Our results suggest that the two Californian mosses are conspecific, and that the Canarian populations belong to this putative species, with only one taxon thus involved. Orthotrichum shevockii (the priority name) is therefore recognized as a morphologically variable species that exhibits a transcontinental disjunction between western North America and the Canary Islands. Within its distribution range, the area of occupancy is limited, a notable feature among bryophytes at the intraspecific level. To explain this disjunction, divergence time and ancestral area estimation analyses are carried out and further support the hypothesis of a long-distance dispersal event from California to Tenerife Island.
... In addition, ecological (moisture, light etc.) and statistical (tree diameter, height, coverage etc.) data were recorded for each relevébased on the field observations. Bryophyte specimens were identifed by consulting keys (Paton, 1999;Mazimpaka et al., 2000;Cortini Pedrotti, 2001;Smith, 2004;Kürschner & Frey, 2011;Lara & Garilleti, 2014;Plášek et al., 2015;Lara et al., 2009;2010;.

In this study, epiphytic bryophyte flora and vegetation were investigated of Boraboy and Destek forests in Amasya province (Turkey). A total of 22 bryophyte taxa (19 mosses, 3 liverworts) were recorded in the research site. As a result of the investigation of 32 sampling releves taken from the trunks by the Braun-Blanquet method, two epiphytic bryophyte associations (Orthotrichetum pallentisand Orthotrichetum striati) belonging to the Ulotion crispaealliance were detected. Among these syntaxa Orthotrichetum pallentiswas recorded for the first time from Turkey. Furthermore, the life forms and life strategies spectrum in syntaxa were analyzed. Analysis result indicates a distinct correlation between life forms, strategies and ecological conditions of the area. Weft and cushion are dominant life forms, Perennial stayers with high sexual reproductive effort is dominant life strategy in the syntaxa. In addition, the ecological characteristics of bryophyte taxa were evaluated. According to these results the largest number of epiphytic bryophytes in the area are mesophytic, sciophyte and subneutrophyte.

Bryological research carried out from 2008 in Tajikistan and Kyrgyzstan brought interesting data on the occurrence of epiphytic bryophytes which have not been recorded yet there. One of the species was recently described as a new ( Orthotrichum pamiricum ) and some of the other newly recorded species are considered as rare or endangered in the region of Middle Asia. To make detailed field monitoring of the species with the aim of mapping their distribution in a wild and complex mountainous terrain, it was necessary in the first instance to identify the area with suitable conditions for the occurrence of these species. We present an innovative modeling program MaxEnt (maximum entropy modeling), which have not previously been used for modeling either epiphytic bryophytes or in the Middle Asia region. Using 205 samples (presence-only data), percent tree cover, and seven uncorrelated bioclimatic variables, regions suitable for the occurrence of the studied species were identified. Distribution models for eight most interesting species of Orthotrichum are presented here ( O. affine , O. anomalum , O. crenulatum , O. cupulatum , O. pallens , O. pamiricum , O. pumilum , and O. speciosum ). They indicated appropriate areas for the most probable occurrence of the species in western Tajikistan, and southwestern and northeastern Kyrgyzstan. These results could serve as guides for future survey expeditions, and aid in the conservation of target species and our understanding of their ecology. Different environmental variables for various species were selected as the most important for modeling. However, for most species higher minimum temperatures and higher precipitation in the wettest month and mean diurnal range were the variables with the greatest contribution to the models.
... In O. dentatum, the segments of the endostome are variably uni-to biseriate with variably thickened walls and the broad base is usually less pronounced. When using determination keys for Europe (Lewinsky-Haapasaari, 1995;Lara et al., 2009), O. dentatum might be mistaken for O. philibertii due to the similarly hairy calyptra. The most striking differences between the two species are the shape of the leaf apex and the calyptra. ...

A new species of Orthotrichum, O. dentatum T.Kiebacher & Luth, is described from the European Alps. The new species belongs to the subgenus Pulchella (Schimp.) Vitt, section Diaphana Vent. Orthotrichum dentatum is similar to O. schimperi Hammar but differs from the latter in that it features a hairy calyptra, denticulate to dentate leaf apices and strongly keeled leaves. Orthotrichum dentatum grows as an epiphyte on a variety of deciduous trees. So far, the new species has only been found in Italy and Switzerland.

Kaufmann, S. & Berg, C. 2014. Bryophyte ecology and conservation in the Troodos Mountains, Cyprus. — Herzogia 27: 165–187. In comparison with other Mediterranean islands, only little is known about the bryophyte flora of Cyprus. Based on data from about 1000 bryophyte samples in the Troodos National Forest Park in spring 2010, we attempt to determine (1) the main characteristics and importance of the bryophyte flora of the Troodos Mountains, (2) the ecological variables responsible for the occurrence of bryophytes, (3) the contribution of the bryophyte flora to nature conservation concepts and, (4) current and future threats to the bryophyte flora of the area. The Troodos National Forest Park contains a substantial proportion of the primary Mediterranean coniferous forests. We collected bryophyte presence and ecological data in 172 ten square meter data plots. We found 113 bryophyte species; most of them were slightly basiophytic, mesophile to slightly drought resistant and moderate thermophilous. Some species, like Fissidens kosaninii, Grimmia ungeri, Oncophorus dendrophilus, Orthotrichum ibericum, Orthotrichum tortidontium, Syntrichia handelii or Zygodon catarinoi are biogeographically interesting, because they can be considered as European endemics. The species number per plot depends on the structural diversity of the plots, and shows some correlation with altitude and slope inclination. Species composition is mainly explained by altitude and the macro-exposition of the habitat. Mean annual precipitation and the Aridity Index are important as well, but collinear with altitude. It is evident that the bryophytes in the Troodos Mountains prefer northerly expositions and locations of higher humidity. Sheltered microclimates enable the bryophytes to colonize areas with lower humidity. The Troodos Mountains represent a highly isolated, extraordinary hotspot for bryophytes, with importance for the whole eastern Mediterranean basin. All habitats in the Troodos National Forest Park belong to protected habitats of the EU Habitats Directive. Our results contribute to the characterization of these habitats. We could not find any substantial anthropogenic threat for the bryophyte flora in the Troodos Mountains. Forest fires and global warming are the most important threat for the bryophyte flora. An upward shift of the species can be assumed, but our results further suggest the possibility that bryophytes move to cooler, north-exposed microhabitats. This underlines the importance of relief, habitat diversity and structural variety for bryophyte conservation strategies.

Işık Mountain is located in the north-east of Ankara in the Central Anatolia region, at the same time it is in the climatic transition zone between the Western Black Sea and Central Anatolia regions. Unfortunately, any studies have not been carried out yet to find out all bryofloristic composition of this region, which is very rich in terms of floristics because of its climatic features and unique topographic structure. In this study, approximately 450 bryophyte samples were collected from 29 different localities of Işık Mountain in June and October 2019. As a result of the examination of these samples 18 liverwort taxa from 10 families and 11 genera, 144 moss taxa from 32 families and 73 genera, and a sum of 162 bryophyte taxa were identified in this region. From these taxa, Dicranella staphylina H. Whitehouse was reported for the second time from Turkey. Moreover, Tortella inflexa (Bruch) Broth. and Weissia rutilans species (Hedw.) Lindb. are new for A2 square. Moreover, 18 taxa for Çankırı province and 49 taxa for Ankara province, for the first time, are given in this bryofloristic list.

We provide an example of ecological vicariance among two epilithic, high mountain taxa of mosses. Phylogenetic analyses using plastid (rps4-trnS, atpB-rbcL, trnL-trnF) and nuclear (EST-115, EST-317, ITS region) markers and morphological data revealed the distinctiveness of the neglected Orthotrichum killiasii, here resurrected from the synonymy of Lewinskya speciosa and newly combined in Lewinskya. Furthermore, our data indicate a speciation process within O. killiasii related to the rock type inhabited (silicate vs. carbonate). We translate this into the recognition of two subspecies, corresponding to O. killiasii s.s. and the recently described O. simonyi. The incongruence between nuclear and plastid markers in some accessions and the partial but rare incongruence between ITS ribotypes and the morphological manifestation in phenotypes indicate incomplete lineage sorting with respect to rather recent segregation and possible gene flow between the two entities.

Abstract: Zechmeister, H. G., Kropik, M., Schachner, H. & Hagel, H. 2020. Notable records of bryophytes in Lower Austria and two first records for Austria. – Herzogia 33: 207–224. Lower Austria is the largest federal province in Austria. Being part of three biogeographical regions, it harbours a highly diverse bryophyte flora, which was well documented in historical reports. However, several places had been neglected. Bryological research has intensified during the last two decades. In this study, we present notable records of bryophytes made between 2017 and 2019: two taxa new to Austria (Cryphaea heteromalla, Orthodontium lineare); records of two species (Orthotrichum urnigerum, Riccia frostii), which have not been found for almost 150 years in Austria; seven more taxa, which are new to Lower Austria (Calliergon richardsonii, Dicranella grevilleana, Obtusifolium obtusum, Orthotrichum dentatum, Orthotrichum rogeri, Schljakovia kunzeana, Syntrichia subpapillosissima); and five species, supposedly extinct in Lower Austria, which have been reconfirmed. Furthermore, new localities for 28 species assessed as endangered or very rare in the Red Data list of Lower Austria are reported, many of which are new for one of the biogeographical regions of the federal province.

A recently presented taxonomical arrangement of the moss genus Orthotrichum Hedw. s.l. substantially changed the traditional view of the taxon that had been accepted throughout the twentieth century. This paper provides the results of mitogenomic studies that strongly support the new taxonomical concept. Comparative analyses presented in this study confirmed the stable structure of moss mitogenomes. Moreover, 17 complete mitogenome sequences were used to identify the major evolutionary groups, including 11 newly sequenced ones, for this study. The analysis of mitochondrial hotspots revealed intron 4 of the cox1 gene to be the most variable non-coding region. The most variable protein-coding genes in the tribe Orthotricheae were ccmFC and tatC. The intergenic and intronic hotspots of Orthotrichum s.l. identified in the present study do not correspond to those described in vascular plant mitogenomes.

The bryoflora of the Gorges de l'Ardèche has been bryoflostically investigated. The previously published records, corresponding to 27 taxa, have been taken into account. Today, 216 bryophyte taxa are confidently recorded in the Gorges de l'Ardèche site. It is considered as a local hot-spot of bryological diversity in a south-eastern France context. Several genera are of special ecological interest: Didymodon, Orthotrichum, Bryum, Fissidens and Riccia. More than 20 remarkable species are additionally recorded: Acaulon triquetrum, Aleniella besseri, Barbula bolleana, Bryum canariense, Cheilothela chloropus, Cinclidotus danubicus, Didymodon nicholsonii, Ephemerum recurvifolium, Fissidens fontanus, Grimmia tergestina, Homalia lusitanica, Homalothecium aureum, Mannia californica, Marchantia paleacea, Orthotrichum philibertii, Orthotrichum sprucei, R. trabutiana, Radula lindenbergiana, Riccia cavernosa, Scorpiurium sendtneri, Timmiella anomala and Tortella inflexa. A significant number of species is largely dependant upon the natural functioning of the Ardèche river, with an intense alluvial activity and remodelling of river banks. Most forest stands are young ones, originating from forest recolonization of ancient pastoral areas. The conservation of the bryophyte communities is very simple and shall be based upon the principle of minimum intervention. An improvement of the waste water disposal systems of many campsites is needed.

Intercontinental disjunct distributions are a main issue in current biogeography. Bryophytes usually have broad distribution ranges and therefore constitute an interesting subject of study in this context. During recent fieldwork in western North America and eastern Africa, we found new populations of a moss morphologically similar to Orthotrichum acuminatum. So far this species has been considered to be one of the most typical epiphytic mosses of the Mediterranean Basin. The new findings raise some puzzling questions. Do these new populations belong to cryptic species or do they belong to O. acuminatum, a species which then has a multiple-continent disjunct range? In the latter case, how could such an intercontinental disjunction be explained? To answer these questions, an integrative study involving morphological and molecular approaches was conducted. Morphological results reveal that Californian and Ethiopian samples fall within the variability of those from the Mediterranean Basin. Similarly, phylogenetic analyses confirm the monophyly of these populations, showing that O. acuminatum is one of the few moss species with a distribution comprising the western Nearctic, the western Palaearctic and Palaeotropical eastern Africa. Pending a further genetic and phylogeographical study to support or reject the hypothesis, a process of long-distance dispersal (LDD) is hypothesized to explain this distribution and the origin of the species is suggested to be the Mediterranean Basin, from where diaspores of the species may have migrated to California and Ethiopia. The spore release process in O. acuminatum is revisited to support the LDD hypothesis, 2015, 180, 30–49.

The conservation of rare and endangered species like Orthotrichum rogeri Brid. requires a precise knowledge of their ecology and distribution. However, the scarcity of financial resources and the inadequacy of chorological data difficult the design of efficient conservation policies. In this context, species distribution models (SDM) can provide useful information to apply conservation measures over large areas like Auvergne region, France (26,000 km 2). Unfortunately, the use of SDM to assist the introduction of conservation measures is uncommon in bryology. O. rogeri is a rare and poorly known moss at the national scale which is well represented in Auvergne. The European Union through the " Habitats and Species Directive " made its protection compulsory. The aim of this work is to use SDM to improve our current knowledge on O. rogeri distribution in order to provide guidance for designing conservation measures. To do so, we first designed a survey to gather presence/absence data and then fit logistic regression model. Model accuracy was assessed using previous knowledge on species occurrences (which have not been used in SDM). The output of the SDM leads us to an improved understanding of the chorology of O. rogeri. Our results showed that this species is clearly too scarcely represented in the Natura 2000 regional network and pointed to the need of targeted surveys. Natura 2000 sites are either too severely fragmented and/or too small to allow efficient conservation of O. rogeri and the suite of related remarkable epiphytes. We suggest that slight modifications of current outline of Natura 2000 sites to allow the integration of several known populations. O. rogeri shows some paradoxical habitat requirements, in some areas it is strongly linked to anthropogenic habitats while in others it is linked to ancient woodlands without anthropogenic activities. Disturbance regime is identified as of prime relevance for the conservation of appropriate habitats. Due to the contrasted requirements of the species diverging conservation strategies could be adopted. Besides, taking into account the various scenarios offers the possibility to anticipate environmental changes caused by global warming and its likely effect for the successful implementation of conservation measures.

Seven species, Orthotrichum alpestre, O. hispanicum, O. pallens, O. patens, O. rivulare, O. scanicum and O. shawii are reported for the first time from the Netherlands. Some taxonomical problems with related taxa are discussed. The sub-alpine, sub-arctic O. alpestre was found at sea level and the plants had rhizoidal gemmae. An old record of O. patens is reinstated, and since 1990 new locations of this species have been found. Orthotrichum rivulare was found epiphytic in a dry plantation of Populus. Orthotrichum scanicum seems to spread in the southern half of the country; O. lewinskyae is probably conspecific. Orthotrichum shawii occurs as a very small local population. Orthotrichum alpestre, O. hispanicum, O. shawii and O. scanicum may have spread long distances from their nearest known localities in Germany, Spain, and Italy. These new findings mostly add to the trend of southern species extending their range into the Netherlands.

A new epiphytic Orthotrichum (O. tortidontium) is described from Mid- Atlas Mountains of Morocco and Betic Sierras of southern Spain. The new species is in subgenus Gymnoporus (Braithw.) Limpr., section Affinia Schimp. and shows the following differential features: long lanceolate, acute or acuminate leaves; emergent, slightly striate capsule; and a peculiar radiate ornamentation of the 16 exostome teeth resulting from the splitting of the original 8-teeth bigeminate exostome. Description and data on the ecology and distribution of the new taxon are provided, as well as S.E.M. micrographs and drawings of the most significant characters.

A new epiphytic moss, Orthotrichum casasianum F. Lara, Garilleti & Mazimpaka, is described, which is characterized by leaves slightly flexuose when dry, linear lanceolate or linear-oblong, with margins recurved and apices obtuse to rounded, frequently concave and mucronate; upper cells with low papillae or almost smooth; capsules emergent, uniformly brown, cylindric-urceolate and strongly ribbed when dry except at base, stomata hemicryptoporous; exostome of 16 teeth fused into 8 pairs, reticulate on the external side and almost smooth on the internal one; endostome of 16 linear, smooth and markedly incurved segments; calyptra naked. The new species is only known from two well preserved riparian woods in Northern Spain, beyond the Mediterranean area. The new moss is taxonomically close to the complex group of holarctic taxa related with O. scanicum Grönv., but is also similar to O. pallens Brid. Characters discriminating the new moss from these species are discussed.

During the last three decades, Orthotrichum shawii Wilson has been considered to be conspecific with O. striatum Hedw. The discovery of new populations of this moss in Southern Europe (N. W. Iberian Peninsula and Sicily) after more than seventy years allowed the re-evaluation of its taxonomical status and relationships. It is concluded that O. shawii is a distinct species, easily distinguished from related species by sporophytic characters: capsule scarcely or not ribbed, exostome of 16 whitish and opaque teeth recurved to the theca when dry, and endostome absent or consisting of eight vestigial segments; additionally, the areolation of the exothecium cells as well as the peristome ornamentation represent significant differences from O. striatum Hedw. that support the specific status of this moss. It is redescribed and keys for its discrimination from closely related species as well as information on its ecology and distribution are provided.

SUMMARY The moss flora of Europe and Macaronesia comprises 278 genera, 1292 species, 46 subspecies and 118 varieties. Of the total 1292 species, 53 are confined to Macaronesia and 21 are thought to be non-native. The checklist was derived from those for the various component countries and regions. It is based on results published up to the end of 2005. Subspecies and varieties are included; hybrids are omitted. The taxonomic hierarchy is based on one published by Goffinet & Buck in 2004. While it has been strongly influenced by results of modern molecular methods, there are still many remaining uncertainties, even at family level. Because of these uncertainties, taxonomic innovation has generally been avoided. There are four new combinations and one change of status.

Based on collections made by the authors in mainland Greece, including the Peloponnese and the island of Evvia, several Orthotrichum records of interest are documented. Orthotrichum acuminatum, O. philibertii, O. tortidontium, O . hispanicum, O. macrocephalum and O. shawii are reported for the first time from Greece, the last three also being new to the eastern Mediterranean. O. rivulare, O. scanicum, and O. alpestre, hitherto doubtfully recorded, are confirmed for Greece and new localities are given for O. stramineum, for which there are few previous records.

The epiphytic bryoflora of the Atlas and Antiatlas Mountains is catalogued, resulting in a list of 65 taxa (63 mosses and 2 liverworts). Twenty-eight new records are reported: four are new to northern Africa, one is new to Morocco and 23 are regional novelties. In addition, a synthesis of the distribution of epiphytes in Morocco is presented, with distributional maps for the main taxa. Five groups of taxa have been established on the basis of their distribution: widely distributed taxa, Rif taxa, Rif and Middle Atlas taxa, Atlas taxa and taxa with localized occurrences. From these distributional patterns, it can be inferred that the occurrence of epiphytic bryophytes is mostly influenced by climatic conditions.

Gametangia distribution, leaf dimorphism and endostome ornamentation and position when dry are new characters that are proposed for a safer discrimination of Orthotrichum rogeri from related species. Additionally, an updated description is given, and, since the holotype is an incomplete specimen, a complementary epitype is designated. In addition, O. stramineum. var. defluens, basionym of O. rogeri var. defluens, is typified, and both names are synonymized with O. stramineum. Finally, the presence of O. rogeri in Spain is discussed, and while the former record of this species in Spain is rejected, several new ones are reported, all of them from the Central Pyrenees.

The discovery of several species known to be rare or very rare in France made it possible to clarify their distribution and ecological affinities at the national level, as well as on the regional scale of the Massif Central. Eight species are concerned: Encalypta longicollis Bruch, Hypnum sauteri Schimp., Orthotrichum hispanicum F. Lara, Garilleti & Mazimpaka, Orthotrichum scanicum Grönv., Orthotrichum shawii Wilson ex Schimp., Orthotrichum stellatum Brid., Seligeria donniana (Sm.) Müll.Hal. and Seligeria recurvata (Hedw.) Bruch., Schimp & W. Gümbel, which were recorded for the first or the second time only on mainland France or in the Massif Central.

Orthotrichum consimile Mitt., earlier regarded as extinct in Europe, is recorded from two new localities: Fuente Urona, Navarra, Spain, and Brilon, Westphalia, Germany. Apart from being smaller, the plants agree well with North American populations. The European specimens are illustrated and the distribution is mapped. Orthotrichum pulchellum Brunt. is excluded from the Spanish moss flora.
Article
The occurrence of Orthotrichum philibertii Vent. in the Iberian Peninsula, Balearic islands and northern Morocco is reported, extending its area to the westernmost Mediterranean basin. The new populations supply some new elements that enlarge the variability range of this species.
Article
Orthotrichum sprucei is reported for the first time from the Mediterranean area of central Spain. Although these populations have the differential characters of O. sprucei, they show interesting morphological variations: much smaller size, bulging leaf cells, and propagules on leaf margins.
Article
After a revision of Orthotrichum specimens kept at LISU and COI, four species (O. urnigerum, O. consimile, O. stramineum and O. scanicum) are reported as new for Portugal, and additional records of two species (O. ibericum, O. speciosum) that had previously been recorded only once in the country, are reported.
Article
Orthotrichum gymnostomum Brid. is first reported from Calabria (Southern Italy); this is the first record of the species in the Mediterranean Area. In addition, six other species are reported as new to the Calabria region (Orthotrichum acuminatum H. Philib., O. alpestre Hornsch. ex Bruch, Schimp. & Gümbel, O. philibertii Venturi, O. scanicum Grönvall, O. stramineum Hornsch., and O. schimperi Hammar), while new localities are given for Orthotrichum anomalum Hedw., O. shawii Wilson, O. speciosum Nees, O. tenellum Brid., and Ulota crispa (Hedw.) Brid., most of which had not been reported for this area after 1950.
Article
Orthotrichum patens Bruch & Brid., considered to be a rare moss in the Iberian Peninsula, is reported from two localities in Northern Spain (Asturias and Navarra). After revision of the herbarium material corresponding to previous records of this species in the Iberian Peninsula, we conclude that most of them (Asturias, Álava, León and La Rioja provinces) are erroneous. However, two early records (Sierra Nevada and Sierra de Ancares) remain uncertain since the corresponding herbarium material has not been found. We also provide details of two new localities of Orthotrichum patens in Romania and two in Turkey, where the species has been poorly recorded. Finally, we discuss the characters that allow the discrimination of Orthotrichum patens from related species, especially from O. stramineum Hornsch., the moss that has most often been confused with it in Spain.
Article
Orthotrichum leblebicii, spec. nov., is described and illustrated. It is compared with O. diaphanum and O. vittii, two Mediterranean species with hyaline hair-points. Two more species, O. macrocephalum and O. scanicum, are for the first time reported from Turkey.
Article
Orthotrichum rivulare, a hygrophytic species, known previously from North America and Europe, is reported from western Turkey. It belongs to subgenus Rivularium (Schimp.) Vitt and shows the following differential features: ovate-lanceolate, obtuse leaves, irregularly dentate leaf apex, and plicate, smooth calyptra. A short description and drawings of the species are provided. In addition, a key to the hitherto known 27 Orthotrichum specimens from Turkey is presented.
