Pileus 5-45 mm broad, conical or hemispherical then slightly expanding to convex, slightly depressed to distinctly umbilicate, with involute then deflexed margin, not hygrophanous, not translucently striate; pink becoming more incarnate or ochraceous with age, often with blue tinge near margin, especially when young, entirely fÀ¬brillose or tomentose then breaking up in minute squamules, especially at centre, often radially splitting at margin with age, showing the context between the fibrils. Lamellae, L = 20-35, l = 3-7, moderately crowded, emarginate, more rarely adnate, segmentiform to subventricose, up to 5 mm broad, white or cream-colour then pink, sometimes with slight grey tinge, with fimbriate or flocculose, concolorous or blackish blue edge. Stipe 20-60 x 15 mm, cylindrical or compressed with longitudinal groove, sometimes broadened at base, creamy at apex, downwards pink, lower half grey-blue or bright blue, often fading with age, minutely pruinose at apex, white tomentose at base, rest glabrous or with scattered innate, bluish fibrils, rarely entirely minutely pruinose. Context thin, membranaceous, concolorous with surface. Smell none or slightly sweetish, like flowers. Taste not distinctive
Spores 9.0-10.5(-11.0) x 6.5-8.0 µm, Q = 1.2-1.3-1.5, irregularly 6-9-angled in side-view. Basidia 4-spored, clampless. Lamella edge entirely sterile. Cheilocystidia 25-75(-100) x 7-20 µm, cylindrical or fusiform, rarely lageniform or with appendiculate apex, colourless or with blue intracellular pigment. Pileipellis a trichoderm with transitions to hymeniderm at centre; a trichoderm with transitions to a cutis at margin, made up of inflated hyphae, 6-22 µm wide with inflated terminal elements, 12-30 µm wide. Stipitepellis a cutis with transitions to a trichoderm, made up of inflated hyphae, 6-22 µm wide with scattered or clustered caulocystidia, especially or exclusively at apex, 30-60 x 22 µm, with or without blue intracellular pigment. Pigment intracellular pink in pileipellis, blue in stipe. Clamps absent.
Habitat: In Central Europe found in subalpine habitats, like Pinus mugo-Salix retusa stands in the alps, in mixed forest with Alnus and Picea, etc., but also occurring inthe lowlands of western and northern Europe in poorly manured grasslands on calcareous soil.
Distribution: wide-spread all over Europe.
