Pileus 17-60 mm, truncate-conical or campanulate, conico-convex, expanding to plano-convex, always with low, broad umbo, with slightly involute margin when young, hygrophanous, when moist dark grey-brown or sepia, sometimes with slight reddish flush (Mu. 10 YR 2-4/2-3, 513; 7.5 YR 3/2), paler at margin (10 YR 3-4/4, 5-6/3, 7/6) translucently striate up to half of radius, sub viscid, strongly pallescent on drying to pale grey-brown, in centre often remaining darker (centre 10 YR 4/3, 4/2, 5/2, rest 10 YR 6/3, 7/3, 8/3), dry, subtomentose at centre (under lens). Lamellae, L = 30-45, l = (1-) 3-7, fairly crowded, deeply emarginate to almost free, rarely narrowly adnexed, ventricose, grey then grey-brown, finally with slight pink tinge (10 YR 7/2, 7/3, 5/2, 5/3, 6/2., 7.5 YR 4-8/2-4) with entire or slightly irregular concolorous or slightly paler edge. Stipe (25-)30-70(-110) x (3-) 4-8(-12) mm, cylindrical, often somewhat flexuose with broadened or attenuated base, pale greyish brown with dense, oppressed, silvery white striation, general appearance whitish, at base often with distinct yellow tinge, particularly when bruised (10 YR 7/3, 7/4, 6/2, 6/3, 5/2, at base 5 Y 8/6, 8/8; 2.5 Y 8/2, 8/4), solid then fistulose. Context pale grey-brown or yellow-brown, firm. Smell weak, sweetish, rarely weakly farinaceous. "Taste indistinct, sometimes unpleasantly rancid with bitterish aftertaste.
Spores 6.5-8.5 (-9.0) x 6.0-7.0 (-7.5)11m, Q = 1.0-1.2 (-1.25), Qav = 1.1, very thin-walled, subglobose in outline, many-angled. Basidia 25-45 x 8-11 µm, 4-spored, clamped. Lamella edge fertile. Cystidia absent. Pileipellis a cutis or ixocutis of radially arranged, cylindrical hyphae, 2.5-5(-7) µm wide with easily disintegrating walls, at centre with ascending, clavate terminal elements; subpellis well-developed, made up of inflated elements, 26-78 x 8-23 µm. Pigment abundant, brown, intracellular in pileipellis (subpellis). Clamp-connections abundant in all tissues.
Habitat & distr. - In groups in moist, mossy, coniferous forest and in moist Calluna-heaths on acid soils. Not uncommon. Rather common in N. and W. Europe. Aug.-Dec.
