Two new lamellar species, Camarophyllopsis olivaceogrisea and Hodophilus glaberripes, of the family Clavariaceae were discovered in the subtropical zone of China. Camarophyllopsis olivaceogrisea is morphologically characterized by its hygrophanous basidiomata, greenish gray to dull green pileus, shortly decurrent lamellae, broadly elliptic basidiospores 4–5.5 × 3.5–4.5 μm in size, and cutis-like pileipellis composed of cylindrical cells. Hodophilus glaberripes is mainly characterized by its white to brownish pileus, glabrous stipe, slight yam bean smell, broadly elliptic basidiospores 5–6.5 × 4–5 μm in size, and epithelium-like pileipellis composed of inflated cells. Phylogenetic placement of the two species was determined by the combined analyses of a DNA data matrix containing ITS and LSU, and showed that collections of the two species formed two independent lineages in the Camarophyllopsis and Hodophilus clades respectively. The delimitation of C. olivaceogrisea and H. glaberripes were evaluated using molecular, morphological, and ecological methods. This is the first report of the genera Camarophyllopsis and Hodophilus in China.
