Abstract: During a field survey of macrofungal resources in Enshi City, Hubei Province, one specimen belonging to the genus Entoloma was collected. The basidiome was medium-sized. The pileus was light brown to dirty white, glabrous, dry, non-viscid, infundibuliform, with an even margin and no striations. The context was white, thin, and without a distinctive odor. The lamellae were relatively dense, decurrent, of unequal lengths, and similar in color to the pileus. The stipe was central, cylindrical, white, solid, fleshy, slightly swollen at the base, and covered with white mycelium. Basidiospores were polygonal to irregular, containing oil droplets. Basidia were ellipsoid to subclavate, with 2-4 sterigmata. Cheilocystidia were elliptical to subelongate and smooth. Clamp connections were present. Based on morphological and molecular phylogenetic evidence, the specimen was identified as Entoloma ammophilum, which was confirmed as a new record species for China.
