In this study, L. medogensis and L. xinjiangensis are described as new species from western China, based on morphological and molecular evidence. L. medo- gensis has only been found on gymnosperms so far and is distinguished by pinkish-buff to clay-buff pileal surface and buff-yellow pore surface, azonate to faintly zonate pileus and ellipsoid to ovoid basidiospores (5–6.2 × 4.2–5.2 μm).
