Pileus 15-30 mm broad, conical or campanulate then conico-convex, usually with small papilla, weakly hygrophanous, when moist not translucently striate or at margin only, olivaceous brown to olivaceous grey, slightly paler when dry, glabrous or with innate fibrillose covering, sometimes minutely squamulose at centre, shining. Lamellae, L = about 30, L = 1-3, distant, narrowly adnate to deeply emarginate, ventricose, grey then grey-brown, finally with pink tinge, with floccose, concolorous edge. Stipe 25-50 x 2-3 mm, cylindrical, sometimes slightly broadened at base, pallid at apex, downwards grey to dark grey with distinct olivaceous tinge, at base often with reddish tinges, entirely striate to floccose with silvery fibrils, base strigose with white or reddish radiating hairs. Context brown-grey with olivaceous tinge in cortex of pileus, grey-brown in upper half of stipe, blackish in lower part of stipe. Smell none or somewhat acidulous-spermatical. Tastenot recorded.
Spores (9.0-)9.5-11.5(-12.5) x 7.0-8.0(-9.0) µm, Q = 1.2-1.5, heterodiametrical, 5-8-angled in side-view. Basidia 4-spored, clampless. Lamella edge heterogeneous. Cheilocystidia (40-) 60 -110 x 10-25 µm, narrowly to broadly lageniform with broad basal part and long, tapering neck with thin, colourless walls, numerous, but always mixed with basidia. Pileipellis a transition between a cutis and a trichoderm, made up of radially arranged, cylindrical to inflated hyphae with up to 20 µm wide terminal elements. Pigment pale olivaceous-brown, intracellular in pileipellis, in addition also minutely encrusting the hyphae of lower pileipellis and upper pileitrama. Clamps absent.
Habitat: terrestrial in mixed or deciduous forest, in road-sides etc., preferably on rich, humose soils; Aug.-Nov.
