However, because these databases are curated independently and updated at different times, inconsistencies in taxonomic placement can occur across platforms. In this study, we compared 10,693 genus-level records from the 2024 Outline of Fungi and fungus-like taxa with corresponding classifications in Species Fungorum, MycoBank, Fungal Names, GenBank and UNITE to evaluate the extent and nature of classification discrepancies among major fungal databases. Classifications were compared at the ranks of family, order, subclass, class, subphylum and phylum. Disagreements were detected at all examined ranks, with the highest number of conflicts occurring at the family level, followed by order, subclass, class, subphylum and phylum. Of the 10,693 genera included, 6,127 (57.29%) had differences between the 2024 Outline of Fungi and fungus-like taxa with corresponding classifications in Species Fungorum, MycoBank, Fungal Names, GenBank and UNITE. To provide biological context for these database-level patterns, selected case studies were examined from major fungal groups (in different ranks), including Agaricales, Diaporthales (Orders), Xylariomycetidae (Sub Class), Dothi¬deomycetes, Eurotiomycetes, Sordariomycetes (Classes), Basidiomycota (Phylum), lichenized fungi, plant pathogens, yeasts, and non-Dikarya (Sub Kingdom). These case studies illustrate how inconsistencies arise from rapid phylogenetic revision, unstable family boundaries, asynchronous database updates, incomplete adoption of recent classifications, inconsistent treatment of incertae sedis taxa, historical classification concepts, and cross-code homonyms. Particularly problematic were cases in which fungal generic names were linked to plant, algal and protist (Microsporidia and Rozellomycota) classifications in broader biological databases. Such inconsistencies have important consequences for fungal taxonomy, biodiversity inventories, ecological studies, sequence annotation, metabarcoding, plant pathology, medical mycology, biotechnology, and conservation research. The purpose of this paper is to show the inconsistencies across the main fungal databases in order to promote a move towards standardization and is not a criticism of any database, which requires huge resources to maintain. We, however, recommend improved synchronization among major fungal databases, the use of stable and kingdom-aware taxon identifiers, clearer treatment of homonyms and uncertain placements, complete hierarchical classifications, versioned updates, and links to supporting literature. This study highlights the need for a standardized, transparent and interoperable fungal classification framework to improve the reliability and reproducibility of fungal research.","PeriodicalId":12471,"journal":{"name":"Fungal Diversity","volume":"20 1","pages":"1"},"PeriodicalIF":20.3,"publicationDate":"2026-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148932499","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Understanding the distribution of phytopathogenic fungi in the major agricultural zones of Qinghai-Xizang Plateau is crucial for the agricultural management of major crops (e.g., highland barley) in the region. The genus <i>Fusarium</i> and its relatives in the family Nectriaceae (Ascomycota, Hypocreales) encompass a diverse array of species with pathogenic and ecological significance, but previous studies to the region have been very limited. This study aims to investigate the diversity and distribution of species belonging to <i>Fusarium</i> and allied genera in Xizang. A hitherto most intensive collection of diseased crops and samples of sediments, soils, and water from adjacent environments of cropland was carried out at 56 sites in Xizang, resulting in the isolation of 916 strains of fusarioid fungi.

In this study, a comprehensive outline for hyaline-spored hyphomycetes is provided and includes 1237 genera with 151 synonyms, which are distributed among six phyla, 27 classes, 97 orders, and 239 families. At the phylum level, <i>Ascomycota</i> (1157 genera) is the dominant group of hyaline-spored hyphomycetes, with <i>Sordariomycetes</i> (506 genera) as the dominant class and <i>Hypocreales</i> (216 genera) as the dominant order in <i>Ascomycota</i>. In <i>Basidiomycota</i>, <i>Agaricomycetes</i> (46 genera) is the dominant class and <i>Agaricales</i> (11 genera) stands as the dominant order. For each accepted genus, notes including sexual morphs, synasexual morph, DNA sequence data and morphology are provided. Based on both morphology and phylogeny, the taxonomic position for 38 genera is re-organized, 22 of which were previously located in <i>Ascomycota</i> genera <i>incertae sedis</i>. DNA sequence data is one of the key components for each genus in our notes. This study represents the most comprehensive analysis to date of hyaline-spored hyphomycetes subjected to multi-gene phylogenetic analysis with combined LSU, SSU and <i>rpb2</i> DNA sequence data. This analysis encompasses 754 hyaline-spored hyphomycetous genera, and recognized three phyla clades, 25 classes and class-level clades, 107 orders and order-level clades, as well as 264 families and family-level clades. Thirty-eight taxa from 30 genera were documented based on fresh collections, utilizing both morphological characteristics and multi-gene phylogeny, resulting in one new genus <i>Parapleurothecium</i>, with one new combination <i>P. obovoideum</i>; 14 new species, viz<i>.

They are a source of organic matter, act as a protective layer in forest soils, and provide a nurturing habitat for micro- and macro-organisms. Through their successional occurrence, litter-inhabiting microfungi play a key role in litter decomposition and nutrient recycling. Despite their importance in terrestrial ecosystems, host tree species and phylogenies’ effect on saprobic fungal dominance and diversity are poorly understood. The present study aims to elucidate saprobic leaf-litter fungal taxonomy, phylogeny and diversity in six phylogenetically related host species in Thailand, using morphological characters and multi locus phylogeny. The host species are &lt;i&gt;Dipterocarpus alatus&lt;/i&gt; (DA) (&lt;i&gt;Dipterocarpaceae&lt;/i&gt;), &lt;i&gt;Nayariophyton zizyphifolium&lt;/i&gt; (NZ) and &lt;i&gt;Microcos paniculata&lt;/i&gt; (MP) (&lt;i&gt;Malvaceae&lt;/i&gt;), &lt;i&gt;Afzelia xylocarpa&lt;/i&gt; (AZ), &lt;i&gt;Dalbergia cana&lt;/i&gt; (DC), and &lt;i&gt;Dalbergia cultrata&lt;/i&gt; (DCul) (&lt;i&gt;Fabaceae&lt;/i&gt;), located in Doi Tung, Chiang Rai Province, Thailand. The selected host species are mostly native to the East Asian region. We hypothesized that tree host phylogeny significantly influences the diversity of fungal communities, and that each community is unique across phylogenetically distantly related hosts. The study revealed one family, two new genera, 15 new species, 13 new host records, and 11 new geographical records with two new combinations of fungi which are treated in detail. Additional taxa identified, mostly to the genus level, were considered for the statistical analysis. In cases where different taxa within the same genus were found but could not be identified to species, they were treated as distinct taxa (e.g., sp. 1 and sp. 2). The statistical analysis was performed to estimate the diversity and relative abundance of each taxon visualized in heatmaps and cluster analysis. The study evidenced multiple levels of diversity and host-preference existing within leaf litter fungi. The reported taxa belonged to the &lt;i&gt;Dothideomycetes&lt;/i&gt; and &lt;i&gt;Sordariomycetes,&lt;/i&gt; 25 families and 31 genera. Most of the saprobic fungi exhibited host-exclusivity, meaning they were observed and recorded exclusively on specific host species and not on others. This resulted in a lower occurrence and overlap of fungi among the other host species. Therefore, the saprobic fungi indicated specialization on particular hosts, and the term \"specialists\" referred to the saprobic fungal taxa that are adapted to thrive on specific host species, rather than generalists that can inhabit multiple host species. Host family level harboured a higher number of unique saprobic taxa than host species level, as evidenced by the statistical analysis. Moreover, the saprobic fungal communities were influenced by seasonal effects during the collecting period. A core group of fungi could be identified as “generalists” observed in all the host species.
