Pileus 15-20 mm broad, hemispherical to conico-convex, often truncate, with umbilicate centre or with small papilla, with deflexed or straight margin, not or weakly hygrophanous, when moist very pale gray or brown with ochraceous tinge, translucently striate at margin up to 2/3 of radius, pallescent to almost white on drying, opaque, strongly radially fibrillose, reminiscent a species of Inocybe, shiny. Lamellae, L = 15-20, l = 1-3, moderately distant adnate-emarginate sometimes with decurrent tooth, triangular to segmentiform or subventricose, pale gray or brown then grayish pink, with entire or fimbriate, concolorous edge. Stipe 25-50 x 1-3 mm, cylindrical sometimes tapering towards base, pale cream­colour or brownish gray, often with distinct ochre tinge usar base, glabrous, polished or with scattered fibrils under lens, at base white tomentose. Context concolorous with surface, very brittle. Smell and taste none.
Spores 9.0-14.0 x (6.7-)7.0-9.0 µm, average 10.0-10.9 x 7.0-7.2 µm, Q = 1.2-1.6, medium O = 1.3-1.4, irregularly nodulose-angled with 5-7 angles in side view, with basal facet. Basidia 27-45 x 10.5-14 µm, 4-spored, clamped. Lamella edge heterogeneous. Cheilocystidia 27­100 x 5-20 µm, irregular in shape, cylindrical to clavate, lageniform or lecithiform, with rounded or capitate apex, numerous. Hymenophoral trama regular, made up of narrow, cylindrical hyphae 6-18 µm wide. Pileipellis a cutis with scattered trichodermal tufts of clavate terminal elements up to 15 µm wide. Pigment pale brown, intracellular in pileipellis. Brilliant granules present in pileitrama. Clamp-connections present in hymenium, elsewhere rare.
