1. The genus Fomitopsis (Polyporales, Basidiomycota) reconsideredViacheslav Spirin, K. Runnel, J. Vlasák, I. Viner, M.D. Barrett, L. Ryvarden, Annarosa Bernicchia, B. Rivoire, A.M. Ainsworth, Tine Grebenc, 2024, izvirni znanstveni članek Povzetek: Based on seven- and three-gene datasets, we discuss four alternative approaches for a reclassification of Fomitopsidaceae (Polyporales, Basidiomycota). After taking into account morphological diversity in the family, we argue in favour of distinguishing three genera only, viz. Anthoporia, Antrodia and Fomitopsis. Fomitopsis becomes a large genus with 128 accepted species, containing almost all former Fomitopsis spp. and most species formerly placed in Antrodia, Daedalea and Laccocephalum. Genera Buglossoporus, Cartilosoma, Daedalea, Melanoporia, Neolentiporus, alongside twenty others, are treated as synonyms of Fomitopsis. This generic scheme allows for morphologically distinct genera in Fomitopsidaceae, unlike other schemes we considered. We provide arguments for retaining Fomitopsis and suppressing earlier (Daedalea, Caloporus) or simultaneously published generic names (Piptoporus) considered here as its synonyms. Taxonomy of nine species complexes in the genus is revised based on ITS, ITS + TEF1, ITS + TEF1 + RPB1 and ITS + TEF1 + RPB2 datasets. In total, 17 species are described as new to science, 26 older species are reinstated and 26 currently accepted species names are relegated to synonymy. A condensed identification key for all accepted species in the genus is provided.

2. Taxonomy and multigene phylogeny of Pseudohydnum (Auriculariales, Basidiomycota)Viacheslav Spirin, Vera Malysheva, Ilya Vine, Vasiliy Dudka, Tine Grebenc, Otto Miettinen, 2023, izvirni znanstveni članek Povzetek: Taxonomy of Pseudohydnum gelatinosum and its sister taxa is revised via morphological data and a four-gene dataset (ITS, nc LSU rDNA, TEF1, RPB1). Identity of P. gelatinosum and Tremellodon pusillus is re-established based on newly collected and sequenced material from their type localities. Pseudohydnum alienum from Europe; P. umbrosum from temperate East Asia; P. cystidiatum, P. meridianum, and P. placibile from Vietnam; and P. omnipavum from North America are described as new to science; P. translucens and P. brunneiceps from East Asia are redescribed. Most Pseudohydnum collections from North America belong to P. gelatinosum ssp. pusillum. A significant divergence of TEF1 sequences in P. gelatinosum is discussed.
