Two new corticioid species,Hyphoderma sinense and H.floccosum(Hyphodermataceae,Polyporales),from southern China
Two new corticioid fungal species,Hyphoderma sinense and H.floccosum from Yunnan Province,southwestern China,are proposed based on a combination of morphological features and molecular evidence.Hyphoderma sinense is characterized by the resupinate basidiomata with smooth hymenial surface,presence of encrusted and moniliform cystidia,and cylindrical to allantoid basidiospores(8-11.5×3-5μm).Hyphoderma floccosum is characterized by the farinaceous hymenial surface,tubular cystidia and leptocystidia,and ellipsoid to allantoid basidiospores.Sequences of ITS+nLSU nrRNA gene regions of the studied samples were generated and phylogenetic analyses were performed with maximum likelihood,maximum parsimony and Bayesian inference methods.The phylogenetic analysis based on molecular data of ITS+nLSU sequences showed that two new species clustered into the genus Hyphoderma,in which H.sinense grouped with H.transiens,and H.floccosum grouped with a clade comprising H.pinicola,H.setigerum and H.subsetigerum.The new taxa are described,illustrated and compared with morphologically similar species.An identification key to 23 accepted species in China is provided.
