摘要

A new poroid wood-inhabiting fungal species, Hyphodermella poroides, is proposed based on morphological and molecular evidences. The species is characterized by resupinate basidiocarps with cream to orange pore surface, a monomitic hyphal system with generative hyphae bearing simple septa, and broadly ellipsoid, hyaline, thin-walled, smooth, IKI-, CB-basidiospores. The phylogenetic analyses based on ITS + nLSU sequences showed that H. poroides formed a single group with a strong support and was closely related to H. corrugata and H. rosae, and then grouped with Pirex concentricus. Both morphological and molecular evidences confirmed the placement of the new species in Hyphodermella.
