Hydnaceous fungi of China 7. Morphological and molecular characterization of Phellodon subconfluens sp. nov. from temperate, deciduous forests

A new hydnaceous fungus, Phellodon subconfluens, from northeast China, is described and illustrated based on morphological characteristics and rDNA ITS sequences. The new species is characterized by circular to flabelliforin basidiocarps, a greyish buff, brownish orange to reddish brown and obscurely zonate pileal surface with white, incurved margins, a monomitic hyphal system with simple-septate, generative hyphae, and broadly ellipsoid to subglobose, thin-walled basidiospores with echinulatc ornamentation. Molecular analysis confirms the phylogenetic position of the new species in Phellodon. The discriminating characters of the new species and closely related species are discussed.
