After taking into account morphological diversity in the family, we argue in favour of distinguishing three genera only, &lt;i&gt;viz&lt;/i&gt;. &lt;i&gt;Anthoporia&lt;/i&gt;, &lt;i&gt;Antrodia&lt;/i&gt; and &lt;i&gt;Fomitopsis&lt;/i&gt;. &lt;i&gt;Fomitopsis&lt;/i&gt; becomes a large genus with 128 accepted species, containing almost all former &lt;i&gt;Fomitopsis&lt;/i&gt; spp. and most species formerly placed in &lt;i&gt;Antrodia&lt;/i&gt;, &lt;i&gt;Daedalea&lt;/i&gt; and &lt;i&gt;Laccocephalum&lt;/i&gt;. Genera &lt;i&gt;Buglossoporus&lt;/i&gt;, &lt;i&gt;Cartilosoma&lt;/i&gt;, &lt;i&gt;Daedalea&lt;/i&gt;, &lt;i&gt;Melanoporia&lt;/i&gt;, &lt;i&gt;Neolentiporus&lt;/i&gt;, alongside twenty others, are treated as synonyms of &lt;i&gt;Fomitopsis&lt;/i&gt;. This generic scheme allows for morphologically distinct genera in &lt;i&gt;Fomitopsidaceae&lt;/i&gt;, unlike other schemes we considered. We provide arguments for retaining &lt;i&gt;Fomitopsis&lt;/i&gt; and suppressing earlier (&lt;i&gt;Daedalea&lt;/i&gt;, &lt;i&gt;Caloporus&lt;/i&gt;) or simultaneously published generic names (&lt;i&gt;Piptoporus&lt;/i&gt;) considered here as its synonyms. Taxonomy of nine species complexes in the genus is revised based on ITS, ITS + &lt;i&gt;TEF1&lt;/i&gt;, ITS + &lt;i&gt;TEF1&lt;/i&gt; + &lt;i&gt;RPB1&lt;/i&gt; and ITS + &lt;i&gt;TEF1&lt;/i&gt; + &lt;i&gt;RPB2&lt;/i&gt; 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. &lt;b&gt;Taxonomic novelties: New species:&lt;/b&gt; &lt;i&gt;Fomitopsis algumicola&lt;/i&gt; Grebenc & Spirin, &lt;i&gt;F. caseosa&lt;/i&gt; Vlasák & Spirin, &lt;i&gt;F. cupressicola&lt;/i&gt; Vlasák, J.

In the past, its taxonomy was difficult due to morphological similarities, which made accurate identification of species difficult. This situation improved and stabilised with recent taxonomic and nomenclatural revisions that modernised &lt;jats:italic&gt;Aspergillus&lt;/jats:italic&gt;, &lt;jats:italic&gt;Penicillium&lt;/jats:italic&gt; and &lt;jats:italic&gt;Talaromyces&lt;/jats:italic&gt;. This was mainly due to the availability of curated accepted species lists and the publication of comprehensive DNA sequence reference datasets. This has also led to a sharp increase in the number of new species described each year with the accepted species lists in turn also needing regular updates. The focus of this study was to review the 160 species described between the last list of accepted species published in 2020 until 31 December 2022. To review these species, single-gene phylogenies were constructed and GCPSR (Genealogical Concordance Phylogenetic Species Recognition) was applied. Multi-gene phylogenetic analyses were performed to further determine the relationships of the newly introduced species. As a result, we accepted 133 species (37 &lt;jats:italic&gt;Aspergillus&lt;/jats:italic&gt;, two &lt;jats:italic&gt;Paecilomyces&lt;/jats:italic&gt;, 59 &lt;jats:italic&gt;Penicillium&lt;/jats:italic&gt;, two &lt;jats:italic&gt;Rasamsonia&lt;/jats:italic&gt;, 32 &lt;jats:italic&gt;Talaromyces&lt;/jats:italic&gt; and one &lt;jats:italic&gt;Xerochrysium&lt;/jats:italic&gt;), synonymised 22, classified four as doubtful and created a new combination for &lt;jats:italic&gt;Paraxerochrysium coryli&lt;/jats:italic&gt;, which is classified in &lt;jats:italic&gt;Xerochrysium&lt;/jats:italic&gt;.

These species do not conform to the revised generic concept and thus necessitate a re-evaluation in terms of taxonomy and phylogeny. The family &lt;i&gt;Chaetosphaeriaceae&lt;/i&gt; (&lt;i&gt;Chaetosphaeriales&lt;/i&gt;) encompasses a wide range of asexual morphotypes, and among them, the simplest form is represented by &lt;i&gt;Chloridium&lt;/i&gt; sect. &lt;i&gt;Chloridium&lt;/i&gt;. The morphological simplicity of the &lt;i&gt;Chloridium&lt;/i&gt; morphotype has historically led to the amalgamation of numerous unrelated species, thereby creating a heterogeneous genus. By conducting phylogenetic reconstruction of four DNA loci and examining a set of 71 strains, including all available ex-type and other non-type strains as well as holotypes and other herbarium material, we were able to gain new insights into the relationships between these taxa. Phylogenetic analyses revealed that the studied species are distantly related to &lt;i&gt;Chloridium&lt;/i&gt; &lt;i&gt;sensu stricto&lt;/i&gt; and can be grouped into two orders in the &lt;i&gt;Sordariomycetes&lt;/i&gt;. Within the &lt;i&gt;Chaetosphaeriales&lt;/i&gt;, they formed nine well-separated genera in four clades, such as &lt;i&gt;Cacumisporium&lt;/i&gt;, &lt;i&gt;Caliciastrum gen. nov.&lt;/i&gt;, &lt;i&gt;Caligospora gen. nov.&lt;/i&gt;, &lt;i&gt;Capillisphaeria gen. nov.&lt;/i&gt;, &lt;i&gt;Curvichaeta&lt;/i&gt;, &lt;i&gt;Fusichloridium&lt;/i&gt;, &lt;i&gt;Geniculoseta gen. nov.&lt;/i&gt;, &lt;i&gt;Papillospora gen. nov.&lt;/i&gt;, and &lt;i&gt;Spicatispora gen. nov.&lt;/i&gt; We also established &lt;i&gt;Chloridiopsiella gen. nov.&lt;/i&gt; and &lt;i&gt;Chloridiopsis gen. nov.&lt;/i&gt; in &lt;i&gt;Vermiculariopsiellales&lt;/i&gt;. Four new species and eight new combinations are proposed in these genera.

They interact with their hosts through either fusion-interaction or colacosome-interaction. Colacosomes are subcellular structures formed by the mycoparasite at the host-parasite interface, which penetrate the parasite and host cell walls. Previously, these structures were detected in 19 fungal species, usually by means of transmission electron microscopy. Most colacosome-forming species have been assigned to &lt;i&gt;Microbotryomycetes&lt;/i&gt; (&lt;i&gt;Pucciniomycotina&lt;/i&gt;, &lt;i&gt;Basidiomycota&lt;/i&gt;), a highly diverse class, comprising saprobic yeasts, mycoparasites, and phytoparasites. In general, these myco- and phytoparasites are dimorphic organisms, with a parasitic filamentous morph and saprobic yeast morph. We investigated colacosome-forming mycoparasites based on fungarium material, freshly collected specimens, and cultures of yeast morphs. We characterised the micromorphology of filamentous morphs, the physiological characteristics of yeast morphs, and inferred phylogenetic relationships based on DNA sequence data from seven loci. We outline and employ an epifluorescence-based microscopic method to assess the presence and organisation of colacosomes. We describe five new species in the genus &lt;i&gt;Colacogloea&lt;/i&gt;, the novel dimorphic mycoparasite &lt;i&gt;Mycogloiocolax gerardii&lt;/i&gt;, and provide the first report of a sexual, mycoparasitic morph in &lt;i&gt;Colacogloea philyla&lt;/i&gt; and in the genus &lt;i&gt;Slooffia&lt;/i&gt;.

Most of these Japanese <i>Claviceps</i> taxa are based on lost specimens or have invalid names, which means many species practically exist only in the scientific literature. The ambiguous identities of these species have hindered taxonomic resolution of the genus <i>Claviceps</i>.

Multilocus phylogenetic analyses based on DNA sequences from LSU, <i>TEF-1α</i>, <i>TUB2</i>, <i>Mcm7</i>, and <i>RPB2</i> revealed the phylogenetic relationships between the Japanese specimens and known <i>Claviceps</i> spp., as well as the presence of biogeographic patterns. Based on the phylogenetic analysis, host range and morphology, we re-evaluated Japanese <i>Claviceps</i> and recognised at least 21 species in Japan.

In this study, we used a citizen science initiative to investigate diseased cereal crops (maize, rice, wheat) from 250 locations, covering the major cereal-growing regions in China. A total of 2 020 <i>Fusarium</i> strains were isolated from 315 diseased samples. Employing multi-locus phylogeny and morphological features, the above strains were identified to 43 species, including eight novel species that are described in this paper. A world checklist of cereal-associated <i>Fusarium</i> species is provided, with 39 and 52 new records updated for the world and China, respectively. Notably, 56 % of samples collected in this study were observed to have co-infections of more than one <i>Fusarium</i> species, and the detailed associations are discussed. Following Koch's postulates, 18 species were first confirmed as pathogens of maize stalk rot in this study. Furthermore, a high-confidence species tree was constructed in this study based on 1 001 homologous loci of 228 assembled genomes (40 genomes were sequenced and provided in this study), which supported the \"narrow\" generic concept of <i>Fusarium</i> (= <i>Gibberella</i>). This study represents one of the most comprehensive surveys of cereal <i>Fusarium</i> diseases to date.

Unlike vegetative hyphae, fruiting bodies grow determinately and follow a genetically encoded developmental program that orchestrates their growth, tissue differentiation and sexual sporulation. In spite of more than a century of research, our understanding of the molecular details of fruiting body morphogenesis is still limited and a general synthesis on the genetics of this complex process is lacking. In this paper, we aim at a comprehensive identification of conserved genes related to fruiting body morphogenesis and distil novel functional hypotheses for functionally poorly characterised ones. As a result of this analysis, we report 921 conserved developmentally expressed gene families, only a few dozens of which have previously been reported to be involved in fruiting body development. Based on literature data, conserved expression patterns and functional annotations, we provide hypotheses on the potential role of these gene families in fruiting body development, yielding the most complete description of molecular processes in fruiting body morphogenesis to date. We discuss genes related to the initiation of fruiting, differentiation, growth, cell surface and cell wall, defence, transcriptional regulation as well as signal transduction. Based on these data we derive a general model of fruiting body development, which includes an early, proliferative phase that is mostly concerned with laying out the mushroom body plan (via cell division and differentiation), and a second phase of growth via cell expansion as well as meiotic events and sporulation. Altogether, our discussions cover 1 480 genes of &lt;i&gt;Coprinopsis cinerea&lt;/i&gt;, and their orthologs in &lt;i&gt;Agaricus bisporus, Cyclocybe aegerita, Armillaria ostoyae, Auriculariopsis ampla, Laccaria bicolor, Lentinula edodes, Lentinus tigrinus, Mycena kentingensis, Phanerochaete chrysosporium, Pleurotus ostreatus&lt;/i&gt;, and &lt;i&gt;Schizophyllum commune&lt;/i&gt;, providing functional hypotheses for ~10 % of genes in the genomes of these species. Although experimental evidence for the role of these genes will need to be established in the future, our data provide a roadmap for guiding functional analyses of fruiting related genes in the &lt;i&gt;Agaricomycetes&lt;/i&gt;. We anticipate that the gene compendium presented here, combined with developments in functional genomics approaches will contribute to uncovering the genetic bases of one of the most spectacular multicellular developmental processes in fungi. &lt;b&gt;Citation:&lt;/b&gt; Nagy LG, Vonk PJ, Künzler M, Földi C, Virágh M, Ohm RA, Hennicke F, Bálint B, Csernetics Á, Hegedüs B, Hou Z, Liu XB, Nan S, M.

The &lt;i&gt;Saccharomycotina&lt;/i&gt; consist of more than 1 200 known species currently divided into 16 families, one order, and one class. Species in this subphylum are ecologically and metabolically diverse and include important opportunistic human pathogens, as well as species important in biotechnological applications. Many traits of biotechnological interest are found in closely related species and often restricted to single phylogenetic clades. However, the biotechnological potential of most yeast species remains unexplored. Although the subphylum &lt;i&gt;Saccharomycotina&lt;/i&gt; has much higher rates of genome sequence evolution than its sister subphylum, &lt;i&gt;Pezizomycotina&lt;/i&gt;, it contains only one class compared to the 16 classes in &lt;i&gt;Pezizomycotina&lt;/i&gt;. The third subphylum of &lt;i&gt;Ascomycota&lt;/i&gt;, the &lt;i&gt;Taphrinomycotina&lt;/i&gt;, consists of six classes and has approximately 10 times fewer species than the &lt;i&gt;Saccharomycotina&lt;/i&gt;. These data indicate that the current classification of all these yeasts into a single class and a single order is an underappreciation of their diversity. Our previous genome-scale phylogenetic analyses showed that the &lt;i&gt;Saccharomycotina&lt;/i&gt; contains 12 major and robustly supported phylogenetic clades; seven of these are current families (&lt;i&gt;Lipomycetaceae, Trigonopsidaceae, Alloascoideaceae, Pichiaceae, Phaffomycetaceae, Saccharomycodaceae&lt;/i&gt;, and &lt;i&gt;Saccharomycetaceae&lt;/i&gt;), one comprises two current families (&lt;i&gt;Dipodascaceae&lt;/i&gt; and &lt;i&gt;Trichomonascaceae&lt;/i&gt;), one represents the genus &lt;i&gt;Sporopachydermia&lt;/i&gt;, and three represent lineages that differ in their translation of the CUG codon (CUG-Ala, CUG-Ser1, and CUG-Ser2). Using these analyses in combination with relative evolutionary divergence and genome content analyses, we propose an updated classification for the &lt;i&gt;Saccharomycotina&lt;/i&gt;, including seven classes and 12 orders that can be diagnosed by genome content. This updated classification is consistent with the high levels of genomic diversity within this subphylum and is necessary to make the higher rank classification of the &lt;i&gt;Saccharomycotina&lt;/i&gt; more comparable to that of other fungi, as well as to communicate efficiently on lineages that are not yet formally named. &lt;b&gt;Taxonomic novelties: New classes:&lt;/b&gt; &lt;i&gt;Alloascoideomycetes&lt;/i&gt; M.
