Lignomyces, a new genus of pleurotoid Agaricomycetes

Collections of a pleurotoid fungus from dead aspen in eastern Russia were initially identified as Lentinus sp., then as Phyllotopsis nidulans. DNA sequencing of cultures derived from these specimens using the nuclear ribosomal 28S (nrLSU) and nuclear ribosomal ITS1-5.8S-ITS2 regions (nrITS) showed t...

Zusammenfassung:Collections of a pleurotoid fungus from dead aspen in eastern Russia were initially identified as Lentinus sp., then as Phyllotopsis nidulans. DNA sequencing of cultures derived from these specimens using the nuclear ribosomal 28S (nrLSU) and nuclear ribosomal ITS1-5.8S-ITS2 regions (nrITS) showed that they were neither Lentinus nor Phyllotopsis and were not related to other pleurotoid genera Hohenbuehelia and Pleurotus. Subsequent investigation showed that the Russian fungus was the same as Pleurotus vetlinianus described from Poland. A new genus, Lignomyces, is described and characterized and L. vetlinianus comb. nov. is proposed.
