Abstract
A new polypore, Antrodia yunnanensis, collected from southwestern China, is described and illustrated based on morphological characteristics and molecular evidence. It is characterized by annual, resupinate basidiocarps with greyish blue to dark greyish blue pore surface upon drying, round to angular pores measuring 2–3 per mm, a dimitic hyphal system with clamped generative hyphae, subicular hyphae bearing fine crystals, and cylindrical, thin-walled, smooth basidiospores measuring 7–9.9 × 2.5–3.1 µm. Molecular phylogeny inferred from ITS and nLSU sequence data showed that samples of A. yunnanensis formed a distinctive lineage in Antrodia sensu lato, and it nested a sister group with A. tropica.
