Abstract: Two specimens of Porodaedalea (Phellinus pini group, Basidiomycetes), collected from Larix sibirica in Finland, were compared with the European-based species P. pini and P. chrysoloma, and other taxa originating from North America, Russia, and China. While differentiation based on fruiting-body characters was difficult, pairing tests and sequence data of the nuclear ribosomal ITS region (ITS-1, 5.8S, ITS-2) showed the collections from Larix sibirica to be distinct and they are suggested as a new species, Porodaedalea niemelaei M.
