Abstract

A new wood-inhabiting fungal species, Fulvoderma yunnanense , is proposed based on a combination of morphological features and molecular data . Fulvoderma yunnanense is characterized by annual, laterally stipitate basidiomata with greyish brown pore surface , a monomitic hyphal system with simple septate generative hyphae , tubular cystidia and broad ellipsoid to subglobose , thin-walled, smooth basidiospores measuring as 4.0– 5.4 × 3.3– 4.8 µm . Sequences of ITS and nLSU rRNA gene regions of the specimens were generated, and phylogenetic analyses were carried out with methods of maximum parsimony, maximum likelihood, and Bayesian inference. The phylogenetic analyses inferred from ITS+nLSU indicated that F. yunnanense nested in Fulvoderma within Hymenochaetaceae. Furthermore, the phylogenetic analysis based on the ITS dataset revealed that the new species formed a well-supported monophyletic lineage with F. australe. Full description, photo plates and a phylogenetic tree to show the placement of the new species are given.
