Agarics (gilled mushrooms) and the order Agaricales include some of the best‐known and most charismatic fungi. However, neither group has had its constituent genera exhaustively compiled in a modern phylogenetic context. To provide that framework, we identified and analyzed 1383 names of genera of agarics (regardless of taxonomic placement) and the Agaricales (regardless of morphology), compiling various data for each name. Including 590 accepted names, the other 793 listed with reasons explaining their disuse, this compendium is intended to be comprehensive at present and phylogenetically up‐to‐date. Data we gathered included type species, continents from which type species were described, accepted synonyms of those species, current family placements, gross macromorphological categories, and sequenced loci (for type specimens, type species, and each genus as a whole). Index Fungorum provided a basis for the data, but much was manually confirmed, augmented, or corrected based on recent literature. Among accepted gilled genera, 82% belonged to the Agaricales; among accepted genera of Agaricales, 67% were gilled. Based on automated searches of GenBank and MycoCosm, 7% of generic names had DNA sequences of their type specimens, 68% had sequences of their type species, and 87% had sequences representing their genus. This leaves an estimated 103 accepted genera entirely lacking molecular data. Some subsets of genera have been sequenced relatively thoroughly (e.g., nidularioid genera and genera described from Europe); others relatively poorly (e.g., cyphelloid genera and genera described from Africa and tropical Asia). We also list nomenclaturally threatened and taxonomically doubtful genus and family names.

The Basidiomycota constitutes a major phylum of the kingdom Fungi and is second in species numbers to the Ascomycota. The present work provides an overview of all validly published, currently used basidiomycete genera to date in a single document. An outline of all genera of Basidiomycota is provided, which includes 1928 currently used genera names, with 1263 synonyms, which are distributed in 241 families, 68 orders, 18 classes and four subphyla. We provide brief notes for each accepted genus including information on classification, number of accepted species, type species, life mode, habitat, distribution, and sequence information. Furthermore, three phylogenetic analyses with combined LSU, SSU, 5.8s, rpb1, rpb2, and ef1 datasets for the subphyla Agaricomycotina, Pucciniomycotina and Ustilaginomycotina are conducted, respectively. Divergence time estimates are provided to the family level with 632 species from 62 orders, 168 families and 605 genera. Our study indicates that the divergence times of the subphyla in Basidiomycota are 406–430 Mya, classes are 211–383 Mya, and orders are 99–323 Mya, which are largely consistent with previous studies. In this study, all phylogenetically supported families were dated, with the families of Agaricomycotina diverging from 27–178 Mya, Pucciniomycotina from 85–222 Mya, and Ustilaginomycotina from 79–177 Mya. Divergence times as additional criterion in ranking provide additional evidence to resolve taxonomic problems in the Basidiomycota taxonomic system, and also provide a better understanding of their phylogeny and evolution.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
