  In the present paper, we revise the taxonomy of the Auriculariales having pedunculate (stalked) basidia. In total, sixteen new species from Europe, East Asia, North and South America, and tropical Africa are described. They are classified among the genera Hydrophana , Mycostilla , Myxarium , Protoacia , Protohydnum , and Protomerulius . In addition, the generic affiliation of eleven extant species is re-established based on phylogenetic and/or morphological evidence. A new genus, Elmericium , is introduced to accommodate a crust-like fungus, E. alabastrinum , from East Asia; phylogenetic data place it in the vicinity of the anatomically similar poroid genera Elmerina and Protodaedalea (Auriculariaceae). The generic description of Protohydnum is amended; in its current scope, the genus encompasses several species formerly assigned to Bourdotia , Ductifera , and Exidiopsis . Available environmental data point to a wider distribution of some Protomerulius spp. and greater species diversity in the genus than currently surmised from physical fungal samples.

  Several species of wood-inhabiting resupinate basidiomycetes are reclassified following examination of type material and sequencing of recent collections. Grandinia ocellata is considered the correct name for Phlebia livida subsp. tuberculata and transferred to Mycoacia. Peniophora avellanea is an older name for Phlebia margaritae and the species moved into Lopharia. Radulum pendulum is identified as the oldest name for the species most commonly called Phlebia albida. Grandinia tuberculata, type species for Stereophlebia, is accepted as a synonym to Radulum pendulum and the combination Stereophlebia pendula introduced. Phlebia canadensis is accepted as an older name for Quasiphlebia densa and the combination Quasiphlebia canadensis proposed. Other new combinations proposed are Cytidiella pallidolivens, Hydnophlebia flavicans, Hyphodermella pallidovirens, Meruliopsis rubicunda, Parvodontia gloeocystidiata, Phaeophlebiopsis roumeguerei, and Rhizochaete galactites. Hyphodermella albostraminea is considered to be a synonym of Hyphodermella pallidovirens. Ceriporia pseudocystidiata is considered to be a synonym of Meruliopsis rubicunda. Meruliopsis faginea is considered to be a synonym of Meruliopsis albostraminea. Typifications are suggested for Corticium seriale subsp. pallidolivens, Kneiffia avellanea, Corticium roumeguerei, Peniophora moelleriana, Grandinia ocellata, Corticium lividum, Thelephora viscosa var. uvida, and Radulum pendulum.

  During studies on the taxonomical delimitation of some species of Funalia, some inconsistencies were observed in the genus. Based on morphological and phylogenetic analyses, Fomitella supina was positioned within the Funalia clade, thus the synonymization of the genus and the new combination of F. supina are proposed. Funalia glabrorigens is also combinated in the genus, while Coriolopsis hainanensis is suggested as a synonym of F. floccosa and F. rigida is assumed as a distinct species from F. floccosa. A table with morphological comparison of the 10 Funalia species confirmed by molecular analyses is also presented.

  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 andFomitopsis. 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.

  Wood-inhabiting fungi (WIF), such as polypores, are extremely species-rich and play vital roles in the functioning of forest ecosystems as decomposers. Despite the importance of polypores, our knowledge of the diversity and distribution of these fungi is still poor in general and especially for West Africa. To advance our knowledge we here summarise results from field collections between 2017 and 2021 and present (i) a taxonomic overview, (ii) phylogenetic placements and (iii) an illustrated catalogue of wood-inhabiting polypore fungi with colour pictures. During the field sampling campaigns, we collected 647 specimens. Based on morphological characteristics and molecular barcode data, 76 polypore species belonging to six orders, 15 families and 39 genera were identified. Of the 76 species, 30 are new to the West Africa, 69 new to Benin, and two new combinations Fuscoporia beninensis and Megasporia minuta are proposed. With this summary, we provide new data for further research.

  Several resupinate poroid Polyporaceae with dextrinoid skeletal hyphae and cylindrical, thin-walled basidiospores have been placed in Dichomitus and Megasporoporia. With the inclusion of DNA sequences, mostly from Chinese material, in the phylogeny of the genera, new genera were recognized, i.e., Megasporoporiella and Megasporia. In the current study, Jorgewrightia and Mariorajchenbergia are described as new genera in the Polyporaceae based on phylogenetic analyses of four gene regions: nuc rDNA ITS1-5.8S-ITS (ITS) and partial Large Subunit (28S), Translation Elongation Factor 1-alpha (TEF1), and RNA polymerase II second largest subunit (RPB2), mostly from Brazilian material. These new genera currently accommodate species formerly placed in Cerioporus, Dichomitus, Megasporia, Megasporoporiella and Pachykytospora. Dichomitus, Jorgewrightia, Mariorajchenbergia, Megasporia and Megasporoporia have mostly resupinate pale-colored basidiomata, poroid hymenophore, usually dextrinoid branched skeletal hyphae, and cylindrical basidiospores. These genera are difficult to differentiate on morphology alone and analyses based on sequences from at least two regions (ITS and 28S), as well as information about geographical distribution, are needed to separate them. Megasporia variabilicolor and Megasporoporia neosetulosa are described as new species, and one neotype and 20 new combinations are proposed. Synoptic tables including characteristics for 27 species from the five genera is presented.

  Taxonomy of Basidiodendron caesiocinereum complex is revised based on morphological and molecular methods (with the use of nc LSU rDNA, ITS and TEF1 regions). The basidiospore ornamentation is justified as a key morphological character for the species recognition in the group. As redefined here, B. caesiocinereum is an angiosperm-dwelling species with smooth basidiospores. Bourdotia cinerella and B. cinerella var. trachyspora are proved to represent separate species with warted basidiospores; they are reintroduced as Basidiodendron cinerellum and B. trachysporum. Additionally, eight new species related to B. caesiocinereum are described based on material from Eurasia, North America and Africa, and identity of B. spinosum from Oceania is discussed.

  Piptoporellus baudonii is proposed as a new combination for Laetiporus baudonii in the Polyporales (Basidiomycota) based on morphological and molecular features. This parasitic macrofungus attacks cashew trees, Eucalyptus, cassava, Tectona, and some indigenous trees in southern regions of Tanzania and poses a serious threat to agroforestry and livelihood conditions in the area. Phylogenetic trees were produced from partial sequences of three rDNA gene regions and a portion of translation elongation factor 1-alpha (TEF1) gene of Laetiporus baudonii for comparisons with samples from the antrodia clade. Our results reveal a strongly supported group of L. baudonii with Piptoporellus in Fomitopsidaceae. Piptoporellus baudonii shares many morphological features with other members of Piptoporellus but differs from them in having broadly ellipsoid or rarely ovoid basidiospores. Both morphological and phylogenetic evidence justify the placement of L. baudonii in Piptoporellus together with the three other known species in the genus.

  The taxonomy of Protomerulius and Heterochaetella is revised based on DNA data and morphological evidence, and their type species, P. brasiliensis and H. dubia, are proved to be congeneric. As a consequence, H. dubia and related species, of which four are described as new, are placed in Protomerulius. Heterochaete microspora is also combined in Protomerulius, and the genus concept is redefined to encompass effused species with smooth or spiny hymenophore and monomitic hyphal structure. Psilochaete multifora, gen. and spec. nov. is a distant relative of Protomerulius spp. found in Norway. Heterochaetella cystidiophora is re-collected in Brazil and placed in the synonyms of Heterochaete sanctae-catharinae. This species does not belong to the Protomerulius–Heterochaetella lineage, and it is transferred to Metulochaete, gen. nov.

Global consortium for the classification of fungi and fungus-like taxa. Mycosphere. ISSN 2077-7000. 14(1), p. 1960–2012. doi: 10.5943/mycosphere/14/1/23. Full text in Research Archive Show summary

  The Global Consortium for the Classification of Fungi and fungus-like taxa is an international initiative of more than 550 mycologists to develop an electronic structure for the classification of these organisms. The members of the Consortium originate from 55 countries/regions worldwide, from a wide range of disciplines, and include senior, mid-career and early-career mycologists and plant pathologists. The Consortium will publish a biannual update of the <i>Outline of Fungi and funguslike taxa</i>, to act as an international scheme for other scientists. Notes on all newly published taxa at or above the level of species will be prepared and published online on the <i>Outline of Fungi</i> website (<a href=https://www.outlineoffungi.org/>https://www.outlineoffungi.org/</a>), and these will be finally published in the biannual edition of the <i>Outline of Fungi and fungus-like taxa</i>. Comments on recent important taxonomic opinions on controversial topics will be included in the biannual outline. For example, ‘to promote a more stable taxonomy in <i>Fusarium</i> given the divergences over its generic delimitation’, or ‘are there too many genera in the <i>Boletales</i>?’ and even more importantly, ‘what should be done with the tremendously diverse ‘dark fungal taxa?’ There are undeniable differences in mycologists’ perceptions and opinions regarding species classification as well as the establishment of new species. Given the pluralistic nature of fungal taxonomy and its implications for species concepts and the nature of species, this consortium aims to provide a platform to better refine and stabilise fungal classification, taking into consideration views from different parties. In the future, a confidential voting system will be set up to gauge the opinions of all mycologists in the Consortium on important topics. The results of such surveys will be presented to the International Commission on the Taxonomy of Fungi (ICTF) and the Nomenclature Committee for Fungi (NCF) with opinions and percentages of votes for and against. Criticisms based on scientific evidence with regards to nomenclature, classifications, and taxonomic concepts will be welcomed, and any recommendations on specific taxonomic issues will also be encouraged; however, we will encourage professionally and ethically responsible criticisms of others’ work. This biannual ongoing project will provide an outlet for advances in various topics of fungal classification, nomenclature, and taxonomic concepts and lead to a community-agreed classification scheme for the fungi and fungus-like taxa. Interested parties should contact the lead author if they would like to be involved in future outlines.
