Genus revisions and new combinations of some North European polypores

Abstract

Two new genera of polypores (Basidiomycota) are described, Erastia Niemelä & Kinnunen, and Rhodonia Niemelä & K.H. Larsson. The following new combinations are presented: Antrodiella canadensis (Overh.) Niemelä, Erastia salmonicolor (Berk. & M.A. Curtis) Niemelä & Kinnunen, Oligoporus balsaminus(Niemelä & Y.C. Dai) Niemelä, Oligoporus immitis (Peck) Niemelä, Oligoporus persicinus (Niemelä & Y.C. Dai) Niemelä, Porodaedalea laricis (Jacz. ex Pilát) Niemelä, and Rhodonia placenta (Fr.) Niemelä, K.H. Larsson & Schigel. Porodaedalea niemelaei M. Fischer is considered to be synonymous with P. laricis, and Sarcoporia polyspora P. Karst. was found to be an older name for the species commonly known as Parmastomyces transmutans (Overh.) Ryvarden & Gilb. or P. mollissimus(Maire) Pouzar.
