The fungal genus Polyporus is an assemblage of white‐rotting lignicolous basidiomycetes. It has undergone considerable expansion and contraction over a period of two and three quarter centuries. Current generic circumscription of Polyporus has kept the genus non‐monophyletic. Species of Polyporus infrageneric group Polyporellus are closely related to some species of Lentinus . We introduce data for ITS2 spacer rRNA secondary structure evolution by quasi‐independent comparison with large subunit rRNA phylogeny, and suggest a fraction of primary nuclear rDNA ITS sequence data as novel taxonomic character. A major taxonomic shift is suggested, supported by molecular and morphological characters, and allowing inclusion of species with gilled hymenophores in Polyporus . Two new names are proposed: Polyporus phyllostipes D. Krüger , nom. nov. and Polyporus gerdai D. Krüger , nom. nov. (© 2004 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
