Taxonomic studies in Chrysoderma, Corneromyces, Dendrophsellum, Hyphoradulum, and Mycobonia

Abstract

Eight poorly known or unusual crustose and pileate basidiomycete species were studied. These included the type specimens of three monotypic genera: Chrysoderma alboluteum from Réunion is conspecific with Cerocorticium molle; Dendrophysellum amurense from the Russian Far East is a species of Vararia; and Hyphoradulum conspicuum belongs in Pseudolagarobasidium and is the first representative of the genus from Europe. Corticium murrillii, from Mexico, is congeneric with Corneromyces kinabalui. New combinations Vararia amurensis, Pseudolagarobasidium conspicuum, and Corneromyces murrillii are proposed. Mycobonia flava and M. brunneoleuca are macroscopically similar species with diagnostically distinct basidiospore shape and size. Mycobonia disciformis is accepted in Mycothele, and Mycobonia winkleri represents a species of unknown affinities. Recent molecular phylogenetic studies indicate that Mycobonia is embedded in Polyporus sensu stricto and is a synonym of Polyporus. Transferring M. brunneoleuca and M. flava to Polyporus requires the creation of the replacement names, P. polyacanthophorus and P. epitheloides.
