Niskanen et al. Agaricineae data files

Genomic-level data have enabled us to create better resolved phylogenies and revolutionized our views on fungal relationships. Agaricineae is the largest suborder of Agaricales and mainly comprises the brown- and dark-spored Agaricales with thick-walled and pigmented basidiospores. Our study is the most extensive phylogenomic study of the suborder Agaricineae to date including 54 genera and 86 species. For 21 of them shallow whole genome sequence data were produced in this study from dried fungarium specimens. A total of 24 families is recognized including five that are proposed as new: Agrocybaceae, Galerinaceae, Hemipholiotaceae, Kuehneromycetaceae, and Phaeocollybiaceae. In addition, Battarreaceae is accepted at family level based on previous phylogenetic studies bringing the total number of accepted families in the suborder Agaricineae to 25. The families are further grouped into eight informal “superfamilies”: Agaricacea, Bolbitiacea, Cortinariacea, Galeropsidacea, Inocybacea, Nidulariacea, Psathyrellacea and Strophariacea. Several families have been emended based on the current study and recent phylogenetic studies and as a result, a total of 184 genera is listed as accepted in suborder Agaricineae. Based on our analysis, most of the families are estimated to have originated and/or diversified in the mid to late Cretaceous or early Paleogene.
