Pileus 10-30 mm diam., convex to pulvinate or expanded and depressed-umbilicate at the centre, margin estriate and incurved, dark brown , densely covered by concolorous or fuliginous small squamules, especially around the umbilicus, dry, not hygrophanous. Lamellae (L 10-14, 1 -15), adnexed or adnate, not decurrent with a tooth, grey when young becoming pinkish beige, with fimbriate, brown gill edge. Stipe 10-25 x 1.5-3 mm, cylindrical, grey-beige to light brown, white towards the base, densely fibrillose, dry, fistulose, single. Context brownish. Odor and taste none.
Spores 8.5-11 x 6-7.5 µm, 5-6-angled. Basidia 30-35 x 9-11 µm, 4-spored. Cheilocystidia forming dense clusters at the edge, consisting of fasciculate hyphae, with clavate terminal cells 25-45 x 7-11 µm), membrane thin-walled, with brown, plasmatic pigment. Pleuro- and caulocystidia absent. Cuticle a palisade of erect, short, cylindrical hyphae, terminal cells (20-40 x 6-10 µm), clavate, with brown plasmatic pigment. Clamp connections lacking.

Pileus 12-20 mm diam., convex becoming campanulate with plane centre, margin not or slightly striate and incurved, beige or light brown, densely velvety, dry, not hygrophanous. Lamellae adnexed and shortly decurrent with a tooth or emarginate, at first whitish turning beige with pink tints, gill edge concolorous and not fimbriate, moderately crowded. Stipe 20-40 x 1.5-2.5 mm, cylindrical, coloured above like pileus, becoming increasingly orange or reddish below, covered by white fibrils next the base, dry, fistulose, solitary. Context beige in pileus, reddish-orange at the base of the stipe. Odor and taste not distinctive.
Spores 8.5-10 x 6.5-7.5 µm, 5-angled. Basidia 32-40 x 10 µm, 4-spored. Cystidia none. Cuticle a cutis of repent or suberect, cylindrical hyphae (8-16 µm diam.), membrane thin-walled, not gelatinized, with brown, plasmatic pigment. Clamp connections absent.
