Adustochaete yunnanensis sp. nov. from China

Abstract

A new wood-rotting fungal species, Adustochaete yunnanensis, is described from China on the basis of morphological and molecular data. The new fungus is characterized by annual, resupinate basidiomata with a grandinioid hymenial surface, encrusted hyphidia, and narrow cylindrical to allantoid basidiospores. ITS and nLSU rRNA sequences were generated from samples and analyzed phylogenetically using Maximum Likelihood, Maximum Parsimony, and Bayesian Inference methods. The phylogeny clustered A. yunnanensis within Adustochaete, where it formed a well-supported independent lineage sister to a clade comprising A. interrupta and A. rava. An identification key to Adustochaete species is provided.
