Pileus 10-50 mm. broad, conical, campanulate or hemispherical, expanding to convex, with slightly depressed centre or not, rarely with minute papilla in central depression, with involute then deflexed, sometimes sulcate margin, not hygrophanous, not or hardly translucently striate, blue-black or indigo, sometimes almost black at centre, slightly paler towards margin, changing to violaceous-brown when old, entirely tomentose or velutinous, breaking up in minute squamules with age, sometimes glabrescent with age. Lamellae, L = 20-40, l = 3-7, moderately distant, emarginate-adnate or almost free, segmentiform to ventricose, up to 5 mm broad, pale to dark blue, grey-violaceous at first then sordid grey­pink with blue tinge, with entire, concolorous or (partly) brown edge. Stipe 20-50 x 2-4 mm, cylindrical or compressed with longitudinal groove, with slightly to distinctly broadened base, dark blue or blue-grey, usually more intensely blue and less dark coloured than pileus, smooth or with pruinose apex, glabrous and polished below, white tomentose at base. Context blue in cortex of pileus and stipe, greyish-blue or whitish in inner parts. Smell none. Taste mild or slightly bitter.
Spores 8.5-12.5 x 6.0-8.5 µm, Q = 1.2-1.7, heterodiametrical, 5-9-angled in side-view. Basidia 4-spored, clampless. Lamella edge sterile. Cheilocystidia 35-75 x 5-25 µm, slenderly to broadly clavate, often with brown, intracellular pigment. Pileipellis a cutis with transitions to a trichoderm at margin, a trichoderm or with transitions to a hymeniderm at centre, made up of inflated terminal elements, 6-22 µm wide. Pigment blue, intracellular in pileipellis. Clamps absent.
Habitat: in grassland, pastures and meadows, from the lowlands up into the alpine zone; july-nov.
Distribution: wide-spread all over Europe, relatively rare.
