Tipizzazione - Holotypus: non esiste; località di raccolta del tipo: Francia.
Pileus 20-70 mm broad, conico-convex or hemispherical then convex finally applanate, with or without small papilla, but also frequently not papillate or slightly to distinctly depressed at centre, with margin involute at first then straight, in old specimens often with undulating marginal zone, hygrophanous, when moist translucently striate up to centre, dark sepia, red­brown, grey-brown or horn-brown, slightly paler towards margin, strongly pallescent along radial streaks on drying, smooth, glabrous, becoming strongly silky-shining when dry. Lamellae, L = 2-5, l = 1-7, moderately crowded, variably inserted from almost free to deeply emarginate, adnate or even with slight decurrent tooth, pale brown then brown-pink finally red-brown with concolorous, entire or irregularly eroded edge. Stipe 20-80 x 2-7 mm, cylindrical or broadened towards base, sometimes compressed with longitudinal groove, concolorous with pileus or slightly paler, strongly silvery striate lengthwise, apex pruinose, base white tomentose. Context concolorous with surface in cortex, in inner parts distinctly paler, hygrophanous, brittle. Smell and taste farinaceous-rancid.
Spores 7-10.5 x 6.5-9.5 µm, Q= 1.0-1.2, isodiametrical, rounded 5-angled in side-view. Basidia 4-spored, clamped. Lamella edge fertile. Cystidia absent. Pileipellis a thin cutis of narrow, cylindrical hyphae, 2.5-12 µm wide. Pigment moderately to coarsely encrusting the hyphae of pileipellis, pileitrama and hymenophoral trama. Clamps present in hymenium, elsewhere rare.
Habitat: in various types of grassland from poor, semi-natural grasslands to fat, manured pastures, lawns, and sportfields; but also in grassy road-sides in forest etc., summer and autumn.
Distribution: Very common all over Europe.
