With the change to one scientific name for fungal taxa, generic names representing sexual and asexual morphs are being evaluated to determine which names represent the same genus and thus compete for use. In this paper generic names of the Agaricomycotina (Basidiomycota), were evaluated to determine synonymy based on their type species. Forty-four sets of sexually and asexually typified names were determined to be congeneric and recommendations are made for which generic name to use. In most cases the principle of priority is followed. However, fifteen generic names are recommended for use that do not have priority and thus need to be protected, specifically: Aleurocystis over Matula; Armillaria over Rhizomorpha; Asterophora over Ugola; Botryobasidium over Acladium, Allescheriella, Alysidium, Haplotrichum, Physospora, and Sporocephalium; Coprinellus over Ozonium; Coprinopsis over Rhacophyllus; Craterocolla over Ditangium and Poroidea; Dendrocollybia over Sclerostilbum and Tilachlidiopsis; Diacanthodes over Bornetina; Echinoporia over Echinodia; Postia over Ptychogaster; Riopa over Sporotrichum; Scytinostroma over Michenera and Stereofomes; Typhula over Sclerotium; and Wolfiporia over Pachyma. Six specific names are proposed for protection: Botryobasidium conspersum, B. croceum, Phanerochaete chrysosporium, Polyporus metamorphosus (Riopa metamorphosa), P. mylittae (Laccocephalum mylittae) and P. ptychogaster (Postia ptychogaster). Twenty-two new combinations are made and three new species are described.
