The genus Peniophora (Russulales, Basidiomycota) from Patagonia revisited

Abstract

The identity of Peniophora specimens from Patagonia is examined based on morphological, cultural, and biological features as well as phylogenetic analyses of nuclear ribosomal ITS and 28S sequences. Three new species are described from Patagonia: Peniophora patagonica, P. pitrae, and P. revoluta. In total, five species are known in the area, growing on endemic trees in Southern Argentina. Peniophora cinerea and P. rufomarginata are excluded from the Patagonian records, and the presence of P. incarnata and P. lycii is confirmed by molecular methods. A key to Peniophora species from Patagonia is presented.
