... Friebes 2011). The present specimen fits quite well the decription in Sherwood (1977) and additional notes in Friebes (2011) in overall habitus, and ascospore and excipular characters. It deviates by the presence of crystals non-soluble in KOH, forming a surficial layer of epihymenium, resulting in a faint pruina of largely hidden disc, and by slightly coloured, distinctly delimited subhymenium, intensifying yellow-orange after adding KOH. ...
Biodiversity is a key criterion in nature protection and often indicates habitats and
localities rich in endangered species. Our research, using 48 one-man one-day field trips,
located an exceptional lichen diversity hotspot and refugium for rare species, the Týřov
National Nature Reserve (Czech Republic, central Bohemia). Within its 410 hectares, we
detected 787 species of lichens and related taxa (675 lichens, 35 semilichens, 58 lichenicolous
fungi and 19 bark microfungi). This is more species of these organisms than has ever been
recorded from such a small area, up to 10 km2
, anywhere in Europe (and probably anywhere in
the world). The species richness is positively correlated with the habitat heterogeneity within
Týřov, which is very far from uniform. In most of the reserve, the species richness is fairly typi�cal for the broader region, and only three sites, with an overall area of a mere 80 hectares, have
distinctly higher species richnesses. The most species-rich site, with 502 species, is only about
25 hectares and is distinctly more diverse in habitats than other sites. The enormous importance
of Týřov for biodiversity protection is emphasized by the nine species described as new to sci�ence: Acarospora fissa, Bacidia hyalina, Buellia microcarpa, Micarea substipitata, Micro�calicium minutum, Rufoplaca griseomarginata, Verrucaria substerilis, V. tenuispora and
V. teyrzowensis. Three species are new to Europe, 55 to the Czech Republic and 191 species are
included in the national Red-list.
... Orbilia flavidorosella resembles O. carpoboloides. The latter was recently described and illustrated by Friebes (2011), and differs in ascospore (*8.5-12.3 × 2-2.3 µm) and ascus measurements (*74-83 × 5.5-6.2 ...
Based on field work and herbarium studies, a taxonomic revision of the genus Orbilia in the Canary Islands was carried out. Eighteen species of the genus are recognized in the present study. Eight of these are new records for the archipelago (Orbilia cejpii, O. euonymi, O. flavida, O. flavidorosella, O. hesperidea, O. scolecospora, O. vinosa and O. vitalbae). Three of them are here described in detail (O. cejpii, O. flavida and O. vitalbae), because they were not reported again since their first publication. Corrections and clarifications about the identity of four previously reported species (O. alnea, O. auricolor, O. delicatula and O. epipora) are provided, being renamed to O. eucalypti, O. tenuissima, O. xanthostigma, and O. dryadum, respectively, the last one being a new combination for O. alnea var. dryadum. Two species with a rather short original diagnoses reported for the Canary Islands are redescribed in detail (O. corculispora and O. gambelii), and those being endemic for the archipelago are illustrated and briefly discussed (Orbilia adenocarpi, O. asomatica, O. pisciformis and O. succulenticola). A key for the identification of these species, a discussion about closely related taxa, notes on their global distribution,
and ecological data are provided.

Within a few decades, the family Orbiliaceae Nannf. has undergone important changes. Being earlier placed in the Helotiales Nannf., the family was transferred in 2003 to a new order (Orbiliales Baral, O.E. Erikss., G. Marson & E. Weber) and a new class (Orbiliomycetes O.E. Erikss. & Baral). The major part of the species generally studied have been reported from humid ecosystems (Liu et al. 2006, Zhang et al. 2009), but the diversity of Orbiliaceae is in fact more important in arid to semiarid ecosystems (Baral et al. ined.). The Macaronesian Region is characterized by its high biodiversity and endemism, and the Canary Islands play a key role within this region (Médail & Quézel 1977, 1999). While Korf (1992) listed 8 species of Orbiliaceae for Macaronesia, in the present research the family turned out as one of the most diverse families in the Canary Islands (~ 60 spp.). Until now, this group has mainly been studied in a taxonomical or descriptive way, but, what do we know about it from an ecological point of view? Tenerife is placed in the middle of the Canary Islands, and it is the perfect place to test out how different climatic or biotic parameters influence the diversity of fungi. During three years, the two larger genera Hyalorbilia and Orbilia were monitored in four types of vegetation from sea–level up to the mountains. Here we show the changes in diversity and abundances of species in different levels of complexity: substrate,
vegetation, altitude, and slope exposition.

by macro- and microscopic photographs, and their host bryophytes are given.
The following species are reported: Arrhenia lobata, Bryocentria brongniartii, B. metzgeriae, Bryoscyphus rhytidiadelphi, Lamprospora benkertii, L. dicranellae, L. esterlechnerae, L. retispora, L. sylvatica, L. tortulae-ruralis, L. tuberculatella, Mniaecia albida, M. jungermanniae, Neottiella ricciae, Octospora affinis, O. bicarpa, O. erzbergeri, O. guestfaliensis, O. gyalectoides agg., O. hygrohypnophila, O. leucoloma var. leucoloma, O. lilacina, O. mnii, O. musci-muralis var. neglecta, O. phagospora, Octosporella erythrostigma, O. jungermanniarum and O. ornithocephala. Three new host bryophytes are given: Lewinskya speciosa for O. affinis, Schistidium trichodon for O. musci-muralis var. neglecta and Syntrichia norvegica for L. retispora. 15 taxa are reported for the first time for Austria and two taxa are reported for the first time for Styria. Octospora guestfaliensis and O. mnii were so far only known from their type localities.
A collection of Nemania aureolutea, a rarely recorded species with a rather north temperate known distribution, is reported for the first time, to our knowledge, from a mediterranean region. the identification of the fungus is based on its morphological characterization, culture characteristics and comparison of the its sequence with those of the type collection. the slight morphological differences encountered in this collection
are discussed and the peculiar environmental characteristics of the region it comes from are outlined.
Im Jahr 2016 wurden die Pilze eines Naturwaldrestes und dreier naturnaher Waldbereiche am Osthang des Ferlacher Horns (Waidisch bei Ferlach, Kärnten, Österreich) erfasst. Die ausgewählten Gebiete zeichnen sich insbesondere durch natürliche, abwechslungsreiche Baumbestände und großen Totholzreichtum aus. Der Schwerpunkt der Untersuchungen lag auf lignicolen und Ektomykorrhiza bildenden Pilzarten. In die Kartierungsliste flossen auch die Ergebnisse einiger Exkursionen in den vorangegangenen Jahren ein. Insgesamt konnten im Gebiet 400 Arten (inkl. Varietäten und Formen) registriert werden. Eine bislang noch unbeschriebene Orbilia-Art ist weltweit nur aus dem Naturschutzgebiet Karlschütt (Steiermark) und dem Untersuchungsgebiet in Waidisch bekannt. Ebenfalls neu für die Wissenschaft ist eine Acremonium-Art, die auf morschem Laubholz gefunden wurde und zu einem späteren Zeitpunkt neu beschrieben werden soll. Die festgestellten Arten werden aufgelistet und einige interessante Funde kurz besprochen. Das Vorkommen mehrerer Arten, die bevorzugt in naturnahen Wäldern wachsen (z. B. Callistosporium pinicola, Ceriporiopsis gilvescens, Dentipellis fragilis, Flammulaster limulatus, Ischnoderma resinosum, Panellus violaceofulvus, Phlebia mellea), unterstreicht die wichtige Bedeutung des Gebietes als Lebensraum für seltene und schützenswerte Pilze.
In 2016 an inventory of the fungal diversity of a virgin forest and three natural forests located on the eastern slope of the Ferlacher Horn (Waidisch near Ferlach, Carinthia, Austria) was carried out. The selected forests are characterized mainly by natural, diverse tree compositions and richness in dead wood. The focus of the study was on lignicolous and ectomycorrhizal fungi. The results of a few field trips in previous years were added, resulting in a total of 400 species (including varieties and forms). A hitherto undescribed Orbilia species is so far only known from the nature reserve Karlschütt (Styria) and the present area. An Acremonium species found on rotten hardwood is new to science and will be published at a later occasion. A list of all recorded taxa is given and several interesting species are briefly discussed. The occurrence of several species that prefer old-growth forests (e. g. Callistosporium pinicola, Ceriporiopsis gilvescens, Dentipellis fragilis, Flammulaster limulatus, Ischnoderma resinosum, Panellus violaceofulvus, Phlebia mellea) emphasizes the importance of the studied locations as habitats of rare fungi worthy of protection.
Im Zeitraum von Anfang 2014 bis Herbst 2015 wurde der westlich von Graz gelegene Jägerberg intensiv auf die dort vorkommenden Ascomycota untersucht. Eine Auswahl der gefundenen Arten wird in dieser Arbeit aufgelistet und kommentiert. Von den insgesamt 53 angeführten Arten sind 10 neu für Österreich (Acanthostigma revocatum, Anteaglonium globosum, Arnium apiculatum, Ceratostomella pyrenaica, Helminthosphaeria stuppea, Phaeotrichosphaeria britannica, Rodwayella citrinula, Stomiopeltis betulae, Synaptospora setosa, Unguicularia incarnatina). Zehn weitere Arten sind Neufunde für die Steiermark (Barbatosphaeria barbirostris, Capronia pulcherrima, Capronia semi-immersa, Daldinia childiae, Lophiotrema boreale s. Holm & Holm p. p., Nectriella halonata, Orbilia comma, Plectania melastoma, Protounguicularia transiens , Trichoderma citrinoviride). Die Ergebnisse dieser und vorangegangener Arbeiten verdeutlichen, dass bei genauerer Suche selbst in einem kleinräumigen Gebiet noch viele bisher selten aus der Steiermark bzw. aus Österreich berichtete (tatsächlich aber wohl häufiger vorkommende) Schlauchpilze zu finden sind.
The Ascomycota occuring on Jägerberg in the west of Graz were studied intensively from early 2014 to fall of 2015. In this paper an annotated selection of the recorded species is provided. Fifty-three species are listed, 10 of which are new to Austria (Acanthostigma revocatum, Anteaglonium globosum, Arnium apiculatum, Ceratostomella pyrenaica, Helminthosphaeria stuppea, Phaeotrichosphaeria britannica, Rodwayella citrinula, Stomiopeltis betulae, Synaptospora setosa, Unguicularia incarnatina). A further ten species are new to Styria (Barbatosphaeria barbirostris, Capronia pulcherrima , Capronia semi-immersa, Daldinia childiae, Lophiotrema boreale s. Holm & Holm p. p., Nectriella halonata, Orbilia comma, Plectania melastoma, Protounguicularia transiens , Trichoderma citrinoviride). The results of this publication, as well as previous studies, illustrate that numerous seldomly reported but probably not so rare ascomycetes in Styria (and Austria) are still to be collected in many more locations upon further field work.
