Online fungal databases are essential resources for nomenclature, classification, sequence identification, biodiversity assessment and applied mycology. 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 stu...
