Notes, outline and divergence times of Basidiomycota

Abstract

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.

A genome-scale phylogeny of Fungi; insights into early evolution, radiations, and the relationship between taxonomy and phylogeny

“…Agaricomycotina + Wallemiomycotina has proven challenging 37,39,55,56 . We too found discordant topologies between concatenation-and coalescent-based analyses (Fig.…”

Mycena genomes resolve the evolution of fungal bioluminescence

“…The genus Mycena (Pers.) Roussel, comprises approximately 600 small mushroom species widely distributed around the world 1 . Also known as bonnet mushrooms, Mycena species are usually characterised by a bell-shaped cap, a thin stem ( Fig.…”

The rise of mycology in Asia

“…Asia has been leading the way in many areas of mycology and in particular in understanding fungal classification. Some of the most significant papers are Families of Dothideomycetes [25], Taxonomy and phylogeny of hyaline-spored Coelomycetes [26], Notes for genera: Ascomycota [27], Outline of Ascomycota: 2017 [28], Notes, outline and divergence times of Basidiomycota [29], Refined families of Sordariomycetes [30], Notes for genera: basal clades of fungi (including Aphelidiomycota, Basidiobolomycota, Blastocladiomycota, Calcarisporiellomycota, Caulochytriomycota, Chytridiomycota, Entomophthoromycota, Glomeromycota, Kickxellomycota, Monoblepharomycota, Mortierellomycota) [31] and Outline of the fungi and fungi-like taxa [32]. These texts are incredibly important to students and young mycologists, providing classifications of most groups of fungi.…”

“…Other important contributions were monographs of Boletales [49] and Amanita [50] and studies on Polyporaceae [51] and advances in the genus Agaricus. However, perhaps the most important advance was the notes and an outline to all Basidiomycota [29].…”
