New national and regional bryophyte records, 75
... Herein an additional amblystegialean species, Drepanocladus capillifolius, is reported for the first time from two localities on the North Island. This is a panholarctic species which was recently recorded at stations in south-eastern Australia and Tasmania (Ellis et al. 2021(Ellis et al. , 2023Ellis, Afonina, et al. 2022). Although it is a distinct species (Ochyra 1989;Ochyra and Matteri 2001), some confusion arose around it because it was amalgamated with D. longifolius (Mitt.) ...
... Since its initial discovery, Ptychostomum touwii has been reported from only one locality in East Cornwall, in the UK (Ellis et al. 2021), and from two regions in northeastern and central France (Tinguy 2022;Ellis et al. 2023). Callaghan and Bijlsma (in Ellis et al. 2021) envisaged that the species is unlikely to be rare, and therefore the absence of further records may be due to the reluctance of some bryologists to deal with the difficult Bryum s.l. ...

Sie erhebt dabei keinen Anspruch auf Vollständigkeit. Zusätzlich sind außereuropäische Arbeiten aufgelistet, die aufgrund der behandelten Arten oder Methoden von Interesse sind. Für aktuelle Veröffentlichungen mit Fokus auf Taxonomie und Systematik sei auf den Beitrag „Taxonomische und nomenklatorische Neuerungen – Moose, von Markus K. Meier in diesem Herzogiella-Heft verwiesen. Für Hinweise auf entsprechende Publikationen für kommende Folge dieser Serie sind wir dankbar.
Background and aim: Bryophytes are an important group of plants in forest ecosystems that act as primary colonizers, moisture regulators and nutrient fixers. Due to their sensitivity to disturbance, they are used as bioindicators in impact studies. Nevertheless, there are extensive areas poorly studied that currently are undergoing significant changes due to agricultural and livestock practices, as is the case in Chaco. As part of a major project which aims to determine the impact on land-use change on the bryophyte diversity in Chaco, samples collected in the region have been analyzed with the aim of updating knowledge of the bryophyte flora in the province. M&M: Samples from preserved and non-preserved areas from Chaco were studied according to the traditional techniques for bryophytes and mounted in water-glycerin-phenol or Hoyer´s solution. Results: As a result, 26 species distributed in 19 genera and 13 families, are newly recorded to Chaco province. Conclusions: The results improved our understanding of a poorly explored flora in a region with unique characteristics. These findings reinforce the value of floristic studies to collect data about poorly known species and their distribution, and to provide a basis for applied studies. In Argentina, despite efforts made in recent decades, there is still a lack of understanding regarding bryophyte diversity. This, combined with rapid changes in land use, may lead to the alteration or disappearance of bryophyte communities before they are even studied.
Cheilolejeunea is the third largest genus of the family Lejeuneaceae (Marchantiophyta) comprising approximately 130 species described globally; approximately 55 have been recorded for the Neotropics. We present here a synopsis of 31 species and four varieties of Cheilolejeunea that occur in the Pacific dominion and Páramo province of tropical America, representing 56% of the Neotropical diversity and ca. 19% of the global diversity of the genus. Most taxa (30 species and four varieties) occur in the Pacific dominion, with Cheilolejeunea schiavoneana being endemic to this dominion; Cheilolejeunea erostrata is endemic to the Páramo province, that registers 10 species and one variety. The highest diversity (26 taxa) is in the Magdalena province. In terms of ecology, Cheilolejeunea is most speciose in the lower montane rainforest (700–2400 m), with 77% of taxa (27) occurring in this ecosystem. We consider Cheilolejeunea erostrata to be Critically Endangered (CR-B1a). The synopsis of the genus includes descriptions of the species, notes on their distributions and habitats, illustrations, and an identification key.
This paper presents the information on the distribution of the moss Bryum gemmiferum R. Wilczek & Demaret in Poland. The first species site from southern Poland was published, but further research and revision of the herbarium materials provided information about its occurrence in different parts of the country. Currently, this species is known in 20 locations. A brief discussion about its ecology, taxonomy, and geographical distribution is given.
An updated checklist of the liverworts and hornworts of Malaysia accepts 773 species and 31 infraspecific taxa of liverworts, in 120 genera and 40 families, and 7 species of hornworts (6 genera, 3 families). The largest family is Lejeuneaceae with 312 species in 30 genera, accounting for 40% of the total number of species. The largest genera are Cololejeunea , Bazzania and Frullania with 90, 61 and 55 species, respectively. The greatest number of species has been recorded from Sabah with 568 species, followed by Pahang and Sarawak with 338 and 265 species, respectively.
On the southern periphery of Badzhal Mountain Range on, an area of about 25 sq. km, we found 313 species of mosses, listed here with distribution along with the altitudinal belts, ecotopes, and substrates. Among them, 73 species are newly recorded for the middle part of Khabarovsk Territory, and 39 of them are new to the whole Khabarovsk Territory, including rare species with no or few previously known records in Russia such as Campylopus gracilis, Sematophyllum substrumulosum, Anomodon solovjovii, Bryoerythrophyllum chenii, Dicranum setifolium, Ditrichum macrorhynchum, Haplohymenium longinerve, Okamurea hakkoniensis, Orthotrichum rogeri, Sphagnum miyabeanum, S. subnitens; identity of several species needs in specially focused taxonomic studies. Studied flora is compared with ones of Zeysky State Nature Reserve, Upper Bureya, and a combined list of mosses of Botchinsky Nature Reserve and Tordoki-Yani Mt. Among all these floras, the proportion of Eastern species in Badzhal is the highest. Main types of vegetation and bryophyte ecotopes are briefly characterized; distribution of species along an altitudinal gradient among considered types of habitats and substrates, is discussed.
New findings of bryophytes are presented
This handbook provides keys, descriptions and illustrations for the 850 species of liverworts and hornworts recorded from Colombia and Ecuador (148 genera, 47 families). The largest genera are Lejeunea (66 spp.), Plagiochila (65), Frullania (54), Radula (33), Metzgeria (33), Cololejeunea (32), Cheilolejeunea (30), Bazzania (26), Drepanolejeunea (25), Ceratolejeunea (18), Diplasiolejeunea (18), and Syzygiella (18). Species descriptions include discussion of characters necessary for identification and taxonomic relationships, worldwide distribution as well as distribution and habitat in Colombia and Ecuador. Descriptions and keys to genera, families, orders and classes are also provided, and their recognition and relationships are briefly discussed. The introduction of the book includes chapters on the history of floristic exploration, diversity, endemism and classification. A glossary, bibliography and index to scientific names are also provided. Since Colombia and Ecuador harbour a large part of the neotropical bryophyte flora, the book may be useful as an identification manual for many parts of tropical America.

The list of species annotated with occurrences in the steppe shrublands, meadow steppes, genuine dry steppes and stony (petrophytic) steppes is provided. Results of the ecological analysis of bryophyte flora are discussed.
New records of 48 species of mosses and liverworts are presented, with detailed notes on their taxonomy, distribution, and ecological characteristics. These findings provide valuable insights for advancing research in biogeography, ecology, and conservation.
Erzberger, P. & Papp, B. (2020): Th e checklist of Hungarian bryophytes-second update.-Studia bot. hung. 51(2): 11-76. Abstract: According to the checklist presented here, the bryophyte fl ora of Hungary consists of 2 species in 2 genera and 2 families of hornworts, 146 species and 3 additional infraspecifi c taxa (1 subspecies and 2 varieties) in 60 genera and 34 families of liverworts, and 521 species and 17 additional infraspecifi c taxa (5 subspecies and 12 varieties) in 186 genera and 64 families of mosses, in total 669 species, 6 subspecies and 14 varieties or 689 taxa. During the last decade, 40 bryophyte taxa (6 liverworts and 34 mosses) were added to the Hungarian bryophyte fl ora (Appendix 1.1), and an additional 19 taxa (4 liverworts and 15 mosses) that were already part of the Hungarian fl ora but not recognised in the previous checklist, are now incorporated in the list (Appendix 1.2). On the other hand, 29 taxa (7 liverworts and 22 mosses) must be excluded according to our present state of knowledge (Appendix 2). Another 13 taxa (2 liverworts and 11 mosses) that are at present not considered members of the Hungarian bryofl ora are annotated in Appendix 3. Th ey were not recognised in the previous checklist (with one exception), but are reported from Hungary in some literature and with fi ve exceptions are also recognised in the European checklist. In many cases we have insuffi cient information to defi nitely decide upon their status. Annotations to all taxa listed in the three appendices provide additional information. In Appendix 4 to all names of bryophyte taxa that appeared in the previous checklist (except excluded taxa) the presently accepted names are assigned.
La especie Pleurozia paradoxa es una hepática de hábitat generalmente paramuno que se encuentra en estado vulnerable según el libro rojo de briófitas de Colombia debido a su poca presencia y su minúscula área de ocupación en el país. Mediante la aplicación de modelos de distribución de especies podemos estimar áreas de idoneidad que dan cuenta de la presencia probable de una especie. En este caso se usó un algoritmo de aprendizaje de máquinas denominado máxima entropía y el software Maxent, con el fin de obtener mapas de distribución potencial. Se emplearon varios registros de presencia y distintos juegos de variables climáticas para el modelamiento, además de un umbral de maximización de la especificidad y sensibilidad en el mapeo. Como resultado, la distribución potencial de P. paradoxa en Colombia se concentró en los departamentos del Cauca, Huila y Nariño a lo largo de la cordillera Central, extendiéndose levemente hacia el Valle del Cauca y Tolima, y en marcada relación con la altitud y el clima de dichas zonas.
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.
Cheilolejeunea is one of the largest genera of Lejeuneaceae and is widely distributed in tropical and subtropical regions. We present a taxonomic revision of the genus in Tropical America. Fifty-four species and six varieties are recognized, in seven sections; the number of accepted neotropical species is reduced about 20 percent. A key to neotropical taxa of Cheilolejeunea is provided and each species and variety is briefly described with data on differentiating characters, distribution and published illustrations. Sixteen new synonyms, two new lectotypifications, and several new taxa are proposed
Gradstein, S.R. (2020): Checklist of the Liverworts and Hornworts of Ecuador. Frahmia 17:1-40. 706 species of liverworts and 16 of hornworts are reported from Ecuador; twenty species are listed as doubtful. Endemism in the country is about 6%. For each accepted species, distribution within the country (by province) and elevational range is given. The disproportionate numbers of provincial records indicate that exploration of the country is still incomplete, with exception perhaps of the Galápagos Islands.
The morphological data of Malesian Lejeunea is described in detail based on examination of about 600 fresh specimens and 1500 herbarium specimens of Lejeunea from other herbaria. Scanning electron microscopy (SEM) images and photographs illustrating the characters of Lejeunea are presented.
Bipolar moss species, extreme examples of large and disjunctive geographical ranges, belong to the most important components of the vegetation cover in Antarctica. Their appropriate taxonomic interpretations are essential for fine-scale biogeographical considerations but our knowledge on their phylogenetic affinities still remains limited. Here, we address the history of the Antarctic populations of Drepanocladus longifolius, a moss species widely considered a bipolar taxon. First, based on a worldwide sampling, we verify its assumed bipolar status. Then, we ask whether its current Antarctic populations have persisted throughout at least the last major glaciation in situ or, alternatively, are they a recent, postglacial element. Phylogenetic analyses together with investigation of morphological characters were used to infer relationships among accessions representing the whole distribution range of the taxon. Morphological and phylogenetic data strictly segregated specimens from the Southern and the Northern Hemisphere, with an exception of Australian populations that were included in the latter group. The Antarctic, sub-Antarctic and South American populations belong to a single clade and are treated as D. longifolius s. str., which consequently is not a bipolar taxon. All Northern Hemisphere populations and the ones from Australia represent D. capillifolius, a lately neglected taxon, which thus displays a true bipolar distribution pattern but not comprising the Antarctic and South American populations. These results provide a sound example of key importance of a detailed taxonomical and phylogenetic treatment as a basis for biogeographical studies. In D. longifolius s. str., a homogeneity in all non-coding nuclear and plastid regions was observed throughout the whole range. It contrasted with the presence of one missense mutation in the rps4 gene in all examined Antarctic populations, which correlated with their distinct ecological situation. While identity of non-coding sequences in D. longifolius populations indicates a postglacial recruitment of extant Antarctic populations from extra-regional locations rather than a long-term in situ survival, the mutation in the rps4 gene may be hypothesised to reflect an adaptive response of plants to the Antarctic environment.
Sphagnum magellanicum has been viewed as being a predominantly circumpolar species in the northern hemisphere, but it occurs in the southern hemisphere and was originally described from the southern parts of Chile. It is an ecologically important species in mire ecosystems and has been extensively used as a model to study processes of growth, carbon sequestration and peat decomposition. Molecular and experimental studies have, however, revealed genetic structure within S. magellanicum, and morphological differences associated with these genetic groups. Here we describe Sphagnum divinum in Sphagnum subgenus Sphagnum (Sphagnaceae, Bryophyta) as a new species, based on molecular and morphological evidence. Sphagnum medium is reinstated as a distinct species and is epitypified. Consequently, a new species concept of S. magellanicum is presented including an epitypification. Important morphological characters to separate these three species in the field and under the microscope are presented. Ecology and distribution differ among the species; S. divinium has a wide habitat range including mire margin, forested peatlands and moist heaths, and a circumpolar distribution around the northern hemisphere. Sphagnum medium seems to be more restricted to ombrotrophic mire expanse habitats and shows an amphi-Atlantic distribution in the northern hemisphere. Sphagnum magellanicum has a very broad ecological niche in peatlands and is found in most mire habitats in Tierra del Fuego on the southern tip of South America.
Lejeunea streimannii, a new species from Papua New Guinea, is described and illustrated. The new species is characterized by the dioicous plants, robust stem with 18‒21 rows of cortical cells and a ventral merophyte 4‒6 cells wide, ovate leaves with a rounded, strongly incurved leaf apex, small lobules with unicelluar first tooth and blunt second tooth, large underleaves with a cordate base, inflated perianths with 5(or 6) crenate, slightly winged keels.

New to Macaronesia are Aneura pseudopinguis, Didymodon brachyphyllus, Diplophyllum obtusifolium, Distichium capillaceum, and Schizymenium pontevedrense. First archipelago reports concern Brachythecium albicans (Canary Islands), Bryum dichotomum (Cape Verde), B. kunzei (Canary Islands), Homalothecium aureum (Cape Verde), Hydrogonium bolleanum (Madeira), Isopterygiopsis pulchella (Canary Islands), Pohlia cruda (Madeira), Pterygoneurum ovatum (Canary Islands), Schistidium flaccidum (Madeira), and Tortella fasciculata (Madeira). First single island reports are given for 42 species.
This paper reports the mosses from Crocker Range Park (CRP) in Sabah, Malaysian Borneo. In total, 293 species, three subspecies and eight varieties belonging to 118 genera and 36 families are reported. This represents about 40% and 47% of the species and infra-specific taxa reported from Borneo and Sabah, respectively. Out of these, six species are new records for Borneo, namely Barbella horridula, Chaetomitrium lancifolium, Distichophyllum leiopogon, Rhaphidostichum luzonense, Rosulabryum capillare and Taxiphyllum taxirameum and 12 species and one variety are new to Sabah. With these additions, the current number of mosses in Sabah and Borneo are 651 and 766, respectively. The largest family of mosses is Calymperaceae with 35 species and one subspecies, followed by Sematophyllaceae with 32 species and two varieties and Pylaisiadelphaceae with 21 species and one variety. In conclusion, CRP has a very high species richness of mosses which is the second highest in Borneo, after Mount Kinabalu.

Based on floristic data and applied taxonomy there are currently 813 species and subspecies in Slovenia - 638 mosses, 173 liverworts and 2 hornworts. Based on the IUCN 3.1 criteria, which we applied to bryophytes following Hallingbäck et al. (1998), there are 164 species (20.17%) listed under threatened categories, of which 121 (18.97%) are mosses and 43 (24.57%) are liverworts; 7 of them (0.86%) are in the CR category, 83 (10.21%) in the EN category and 74 (9.10%) are listed under the VU category. There are 23 species (2.83%) in the near threatened (NT) category, while 163 species (20.05%) are data deficient (DD). The Least Concern (LC) category currently comprises 463 (56.95%) species.
We investigated whether the European near-endemic moss Drepanocladus lycopodioides has declined in its core distribution area in the southern Baltic Sea region and explored potential explanations for this. First, we re-visited sites with documented records from 1854 to 1957 in the Stockholm archipelago and nearby mainland in southern Sweden. Second, we compared the numbers and distributions of Swedish occurrences, their habitats, and substrates up to 1950 (289 herbarium records), and from 1951 onwards (347) using different map layers. Third, we explored whether inter-annual variation in reproductive performance was related to moisture conditions at five sites on an island in the Stockholm archipelago during nine years. We estimated moisture conditions based on precipitation data and dry days during the time when fertilization occurs in the year prior to sporophyte maturation. Drepanocladus lycopodioides has strongly decreased in intensively managed agricultural landscapes but remains frequent in natural or semi-natural habitats on limestone. Sporophyte development varied between years and depended on the weather condition during the fertilization period. Climate forecasts for the study area predict longer dry spells during late spring to late summer, which coincides with the timing of sexual branch initiation and fertilization in the species. We expect that sporophyte production will likely decrease in the future, which will affect the species’ abilities to re-colonize spots where it vanishes during years with poor growth conditions.
Guide to the species of the moss family Bryaceae in Western & Central Europe and Macaronesia
Three new additions to the knowledge of Lejeunea species in the Paleotropical bryoflora with their distributional ranges are presented. A new species, Lejeunea konratii G.E.Lee & Pócs, from Fiji (Central Viti Levu) is described and illustrated. It is characterized by the peculiar (1)–2 cells long first tooth of leaf lobules, the robust stem with 16–24 epidermal cells and ventral merophytes 4–8 cells wide, the reniform underleaves, the smooth cuticle, the leaf cells without well-developed trigones and intermediate thickenings, and the 2-winged, auriculate and undulate keels of the perianth. All Asian and Pacific species of Lejeunea with pluricellular lobule teeth are compared and discussed.
Molecular sequence data provide convincing evidence that Tortella bambergeri (Schimp.) Broth., as understood over the last three decades, consists of two species. On the other hand, a careful investigation of the holotype of Trichostomum bambergeri Schimp. revealed its synonymy with Tortella tortuosa (Hedw.) Limpr. (in its current broad sense), which was confirmed by the molecular sequences of two plants from the Alps that were morphologically similar to the T. bambergeri type and that proved to be unrelated to the European plants currently so named. For T. bambergeri auct., two validly described names were located, T. fasciculata (Culm.) Culm., a suboceanic-submediterranean floristic element, and T. pseudofragilis (Thér.) Köckinger & Hedenäs, comb. nov., a boreo-montane element. Lectotypes for these two names are designated. Beside molecular differences, the two species can be distinguished mainly by having differently shaped cells on the upper leaf margin and by differences in the orientation of the dry leaves. Distribution and ecology of these two taxa are discussed. A key to Tortella (Müll.Hal.) Limpr. species with quadrate superficial cells on the dorsal, upper costa is provided. Hybrid sporophytes in T. pseudofragilis, with T. tortuosa (Hedw.) Limpr. as the male parent, are discussed in the light of other observations, including an apparent hybrid T. pseudofragilis × inclinata from Sweden, suggesting that hybridisation may be important in the evolution within Tortella.
Sphagnum magellanicum Brid. is a worldwide distributed peat moss and an ecosystem-engineer in temperate and boreal bog ecosystems suggesting a great adaptive potential to different environmental conditions. Phenotypes of S. magellanicum have been described as one species so far, although this has been questioned by the detection of several genetic groups in a recent global study. Concordant with morphological uniformity, our analyses of Mid- to Northern European plants revealed only minimal variation in nuclear nrITS and plastid rps4 sequences. However, we detected two distinct genetic groups within Europe by analyzing microsatellite data of 298 individuals from 27 populations. Plants formed an Eastern and a Western European cluster, with overlapping areas in northern Germany and southern Sweden where plants of both clusters coexist within populations but show no signs of admixture. These two cryptic taxa seem therefore to be reproductively isolated. Bayesian analyses indicated that reproductive isolation occurred before the end of the late Pleistocene glaciations. After the meltdown of the glaciers, both clusters colonized northern and central Europe from glacial refugia in the West and possibly from Euro-Siberian populations.
To test for divergent adaptation to environmental conditions, we exposed plants of both clusters to experimental climate warming treatments at two different plant-diversity levels (monocultures vs. mixtures) for two years. Despite their different evolutionary history, plants of both genetic clusters responded equally to climate treatments in our southern common garden near Potsdam, Germany. However, only eastern cluster populations benefited from plant-community diversity and increased their biomass in mixtures. These differences in their ecological niche match the diverging microhabitat preferences observed in situ and may effectively hamper genetic exchange if distances between microhabitats are too large for Sphagnum sperm movement.
