Phylogenetic relationships ofHydnum peroxydatumsupport the synonymy ofHydnochaetewithHymenochaete(Hymenochaetaceae, Agaricomycetes)

A combined dataset of rDNA ITS and LSU sequences was used to infer the phylogenetic relationships of Hydnochaete peroxydata (≡ Hydnum peroxydatum), the type species of Hydnochaete. The species was retrieved nested within the Hymenochaete s. str. clade; therefore Hydnochaete is regarded as a synonym of Hymenochaete and the new combination Hymenochaete peroxydata is proposed.
