Remarks (internal):Entoloma pseudogriseoalbum is characterized by the umbilicate pileus, cuboid basidiospores and abundant cylindrical cheilocystidia.
In the original protologue, the basidiospores were described as 12-13 x 10-12 µm, and cheilocystidia were absent (Bi et al. 1986). However, the basidiospores of the type collection are less than 10 µm in size, and the cheilocystidia are abundant, forming a sterile band on the lamellar edge. Two collections collected from Heyuan (GDGM 20485) and Yangchun (GDGM 21738) not far from the type locality are identical with the holotype of E. pseudogriseoalbum.
Entoloma talisporum Corner & E. Horak, originally described from Papua New Guinea, resembles E. pseudogriseoalbum in its small basidiomata, subumbilicate whitish pileus, subdecurrent lamellae, and cuboid basidiospores, but differs in its smaller basidiospores (6-8 µm) and absence of cheilocystidia (Horak 1976).

Revised description
Basidiomata small. Pileus 6-14 cm broad, convex to campanulate at first, expanding to plano-convex or applanate, with a slightly depressed or subumbilicate center, sometimes with a small and indistinct papillae in the depression, smooth, tomentulose to minutely squamulose in the center, whitish when young becoming pale brownish, radially striate almost to center, dry, not hygrophanous, with straight and entire margin. Lamellae subdecurrent, moderately distant, ≤2 mm broad, white at first becoming pinkish with age, thin, with concolorous and irregular edge, with 2 tiers of lamellulae. Stipe central, 20-50 x 1-2 mm, cylindrical, equal, hollow, innately fibrillose, dry, with white tomentum at base. Context white, thin. Odor not distinctive, taste mild.
Basidiospores 7.0-9.0 µm, cuboid or quadrate in profile view, relatively thin-walled. Basidia 34-47 x 10-12 µm, clavate, 4-spored, with sterigmata of 4-5 µm in length, without clamp-connections at base. Lamellar edge sterile. Cheilocystidia in clusters along the lamellar margin, cylindrical to narrowly clavate, 50-110 x 6-10 µm, hyaline, thin-walled. Pleurocystidia absent. Hymenophoral trama parallel, made up of cylindrical elements. Pileipellis a cutis with a transition to a trichoderm, terminal cells cylindrical to subclavate, 7-12 µm wide, with pale yellow brownish, intracellular pigment. Pileitrama regular of cylindrical hyphae. Stipitipellis a cutis of narrow and cylindric hyphae, 3-9 µm in diameter. Caulocystidia absent. Brilliant granules absent. Oleiferous hyphae rare. Clamp connections present in all tissues.
Habitat: Scattered or solitary, on soil in deciduous woods.
