Pileus 15-60 mm broad, conico-campanulate or conico-convex, expanding to plano-convex usually with low, broad rarely acute umbo, rarely with slight central depression, with involute then deflexed margin, distinctly hygrophanous, when moist dark brown or red-brown, not translucently striate, pallescent on drying, adpressedly radially fibrillose with micaceous patches, glabrescent. Lamellae, L = 22-40, l = 1-3, moderately crowded, broadly adnate or slightly emarginate, segmentiform to subventricose, sometimes transvenose, pale grey then grey-pink, with brown, fimbriate edge. Stipe 25-60 x 2-7 mm, cylindrical or slightly broadened towards base, grey-brown to white, densely fibrillose-striate, often twisted, apex sometimes distinctly pruinose, base white or creamy-yellow. Context pallid. Smell farinaceous, rarely with coconut component. Taste farinaceous-rancid.
Spores (8-)9-12(-12.5) x (6-)7-8.5(-9) µm, Q = 1.2-1.6, heterodiametrical, 6-8-angled in side­view. Basidia 4-spored, clamped. Lamella edge sterile. Cheilocystidia 20-70 x 8-20 (base) x 2-97 µm (neck), clavate, lageniform, lecithiform or tibiiform, with brown, intracellular pigment. Pileipellis a cutis, rarely with transitions to a trichoderm, made up of cylindrical to inflated elements, 5-15(-20) µm wide. Pigment brown, intracellular in pileipellis. Clamps abundant.
Habitat: Solitary or in groups on peaty soil in heaths (Calluna, Empetrum) and in living Sphagnum, summer-autumn.
Distribution: Common and abundant in atlantic peat-bogs of the United Kingdom, rare in central european mountain bogs.
