ABSTRACT=<p>Two new species of <italic>Antrodia</italic>, <italic>A. aridula</italic> and <italic>A. variispora</italic>, are described from western China. Phylogeny based on a six-gene dataset (ITS + nLSU + nSSU + mtSSU + TEF1 + RPB2) demonstrates that samples of the two species form two independent lineages within the clade of <italic>Antrodia s.s.</italic> and are different in morphology from the existing species of <italic>Antrodia</italic>. <italic>Antrodia aridula</italic> is characterized by its annual and resupinate basidiocarps with angular to irregular pores of 2–3 mm each and oblong ellipsoid to cylindrical basidiospores measuring 9–12 × 4.2–5.3 μm, growing on gymnosperm wood in a dry environment. <italic>Antrodia variispora</italic> is characterized by its annual and resupinate basidiocarps with sinuous or dentate pores with a size of 1–1.5 mm each and oblong ellipsoid, fusiform, pyriform, or cylindrical basidiospores measuring 11.5–16 × 4.5–5.5 μm, growing on the wood of <italic>Picea</italic>. The differences between the new species and morphologically similar species are discussed in this article.</p>
