Pileus 35-145 mm, conical at first then slightly to distinctly expanding to convex with distinct umbo, finally more or less applanate with conical umbo, with margin involute when young, later more or less straight, not hygrophanous, not translucently striate, lilac brown or purple brown fading with age to brown with slight purple tinge, slightly paler towards margin or not, innately radially fibrillose or rugulose, offen with micaceous patches, usually fairly regular, sometimes, however, irregularly fibrillose costate, becoming tomentose or subsquamulose when dry, shiny. Lamellae, L = 35-75, l = 1-7, fairly distant to moderately crowded, free or deeply emarginate, segmentiform then ventricose up to 20 mm broad, white or cream colar when young, then with pink tinge finally brown pink, with irregular, dentate or eroded, concolorous edge. Stipe 40-175 x 4-20 mm, cylindrical, offen more or less fusiform, tapering towards apex and base, apex white or pallid, downwards with purple brown fibrillose to almost flocculose or squamulose covering on paler background, sometimes with yellowish tinge at base, solid or narrowly fistulose with age. Context fairly thick and tough, concolorous with surface in cortex of pileus and stipe, in inner parts white. Smell none or sweetish. Taste mild or slightly unpleasant, sometimes more like nuts or somewhat sweet.
Spores 8.0-12.0 x (5.5-)6.0-8.0 µm, Q = 1.2-1.7, irregularly many angled in side view. Basidia 2- or 4-spored, clamped. Lamella edge heterogeneous, rarely sterile. Cheilocystidia 20-60 x 7-20 (at base) x 2.5-7 (neck) x 3-15 (capitulum) µm, lageniform to lecithiform with broad base, rostrate or capitate, rarely moniliform neck. Pileipellis a cutis with transitions to a trichoderm, made up of up to 25 m wide, inflated hyphae, with clavate or lusiform terminal elements, 50-140 x 5-25 µm. Pigment brownish, intracellular in pileipellis and stipitispellis. Brilliant granules absent. Vascular hyphae present or absent. Clamps present and abundant in all tissues.
Habitat: In poorly manured, semi-natural grasslands and haylields, or in ape n woodland, dwarl-shrub vegetations (Salix repens, and various other dwarl willows in boreal, subarctic or subalpine habitats. Summer-Autumn.
Distribution: Wide spread and fairly common in boreal and temperate Europe.
