Polyporales is strongly supported as a clade of Agaricomycetes, but the lack of a consensus higher-level classification within the group is a barrier to further taxonomic revision. We amplified nrLSU, nrITS, and rpb1 genes across the Polyporales, with a special focus on the latter. We combined the new sequences with molecular data generated during the PolyPEET project and performed Maximum Likelihood and Bayesian phylogenetic analyses. Analyses of our final 3-gene dataset (292 Polyporales taxa) provide a phylogenetic overview of the order that we translate here into a formal family-level classification. Eighteen clades are assigned a family name, including three families described as new (Cerrenaceae fam. nov., Gelatoporiaceae fam. nov., Panaceae fam. nov.) and fifteen others (Dacryobolaceae, Fomitopsidaceae, Grifolaceae, Hyphodermataceae, Incrustoporiaceae, Irpicaceae, Ischnodermataceae, Laetiporaceae, Meripilaceae, Meruliaceae, Phanerochaetaceae, Podoscyphaceae, Polyporaceae, Sparassidaceae, Steccherinaceae). Three clades are given informal names (/hypochnicium,/climacocystis and/fibroporia + amyloporia). Four taxa (Candelabrochete africana, Mycoleptodonoides vassiljevae, Auriporia aurea, and Tyromyces merulinus) cannot be assigned to a family within the Polyporales. The classification proposed here provides a framework for further taxonomic revision and will facilitate communication among applied and basic scientists. A survey of morphological, anatomical, physiological, and genetic traits confirms the plasticity of characters previously emphasized in taxonomy of Polyporales.
