Even more fibre-caps (2): Thirteen new species of the family Inocybaceae.

Summary: We here present thirteen new species of the family Inocybaceae: three species of genusInosperma, Is. dodonae, Is. ismeneanum und Is. monastichum, three species of genus as well as seven species of genus Inocybe, I. audens, I. dvaliniana, I. gandalfiana, I. jucunda, I. pipilikae, I. prisca und I. timpetuana. The two latter named species and I. gandalfiana are nodulose-spored. All species are described in detail, macro- and micro-photographs and micro-drawings are presented. They are compared to 57 types of molecularly related or in some way morphologically similar species, of which 36 were studied. Sequences (ITS and LSU) of the holotypes of the new species are available in GenBank. The infrageneric placement of the new species is discussed. Detailed descriptions of the new species in English are available on Mycobank.Pseudosperma, P. emberizanum, P. huginii und P. solare

Contribution to the family Psathyrellaceae III: Britzelmayria multipedata, Psathyrella psammophila (= P. obtusata s.l.), Psathyrella rostellata.

Summary: Britzelmayria multipedata, Psathyrella psammophila and Psathyrella rostellata, three species of the family of the Psathyrellaceae, are described in detail macro- and microscopically. Their ecological demands and the current distribution in Bavaria are discussed. The determination as Psathyrella psammophila is confirmed by comparison with the type sequences of Psathyrella angusticystis and P. psammophila. The identity with Psathyrella angusticystis is confirmed. Since the species conception of Psathyrella obtusata has not been clarified due to a lack of typification and more than one taxon can be hidden under this name in the broader sense, the name Psathyrella psammophila is used for the presented Bavarian collections of Psathyrella obtusata s.l.

Clitocybula familia and Clitocybula lacerata in Bavaria.

Summary: Clitocybula familia, collected in the Bavarian Limestone Alps (Ester-Mountains), is presented and discussed in detail as first record for Bavaria. A remarkable feature of the collection is a pronounced heterosporism. Nonetheless the determination as Clitocybula familia is based upon sequence data (ITS-region) and on macro- and microscopical features. The circumscription of the species is emended by the possible heterosporism. Additionally two macro- and microscopical distinctly different Upper Bavarian collections of Clitocybula lacerata, are described in detail, depicted, and discussed. Sequence data (ITS-region) confirm the conspecifity with the neotype of Clitocybula lacerata.

Gloiodon strigosus – a second Bavarian and Germanrecord after more than 40 years.

Summary: A recent Upper Bavarian find of Gloiodon strigosus, which is very rare in Central Europe and has previously been missing in Germany for over 40 years, is presented. The macroscopic and anatomical features are described in detail and represented by micro and macro photos. A detailed comparison of the habitat of the presented collection with the location conditions of three earlier records from Austria reveals as common features permanently high humidity, a relative high protection value of the habitat and a moderate to warm microclimate. The high humidity and the preference for near-natural site conditions are confirmed by the evaluation of publications of finds of G. strigosus in Scandinavia and Poland as important factors for the occurrence of this species. Occurrences of G. strigosus therefore have an extremely high nature conservation value. Due to the rarity, the high habitat requirements and the strong decline (also missing in Austria for almost 40 years), a very high classification is strongly recommended for future revisions of the Red Lists of the endangered Macrofungi of Bavaria respectively of Germany.

Lorenz S (2021) Dicranophora fulva recorded again in Germany after more than 80 years.

Summary: A Bavarian collection of the so far rarely observed, fungicolous species Dicranophora fulva is presented on Suillus variegatus. The description of the find circumstances with emphasis of the weather conditions shall contribute to its knowledge. Longer lasting, dry conditions and low occurrences of potential host fruiting bodies do not seem to have a decisive effect on fructification. The appearance only after damage of the host confirms the low pathogenic potential of Dicranophora fulva.
