A new wood-inhabiting fungal species, Eichleriella xinpingensis, is described based on a combination of morphological features and molecular evidence. The species is characterized by an annual, resupinate basidiocarps with soft leathery to ceraceous hymenial surface covered by blunt-pointed spines, a dimitic hyphal system with clamp generative hyphae, two-celled, narrowly ovoid to obconical basidia and broadly cylindrical, hyaline, thin-walled, smooth, basidiospores measuring as 6.5–10 ×3.5–4.5 µm. Sequences of ITS and LSU nrDNA regions of the studied samples were generated, and phylogenetic analyses were performed with maximum likelihood, maximum parsimony and Bayesian inference methods. The phylogenetic analyses showed that E. xinpingensis belonged to the Auriculariaceae and was closely related to E. tenuicula.
