Remarks (internal):Entoloma lepidissimum is distinctive on account of its very dark blue fruitbodies, smooth, polished stipe, bluish lamellae, and scattered cheilocystidia. Entoloma coelestinum has much smaller spores, and white lamellae when young.

Pileus 5-25(-30) mm broad, conical, campanulate, hemispherical or convex, sometimes with small papilla, never distinctly depressed, with involute then straight margin, not hygrophanous, not translucently striate or at margin only when moist, deep blackish blue, radially fibrillose, rarely squamulose at centre, not or very slightly pallescent on drying, shining. Lamellae, L = 15-25, l = 0-3, moderately distant to distant, adnate sometimes adnexed or deeply emarginate, sometimes almost free, segmentiform to ventricose, pale blue-grey when young then pink, often retaining its blue colour for a long time, with concolorous or slightly paler edge. Stipe 25-60 x 1-3(-4) mm, cylindrical or compressed, dark blue, concolorous with pileus or slightly paler, smooth, polished or with some scattered fibrils. Smell and taste not distinctive.
Spores 7.5-11 (-12) x 6-8 µm, Q = 1.2-1.6, heterodiametrical, irregularly 6-8-angled in side­view. Basidia 4-spored, clamped. Lamella edge heterogeneous, rarely fertile. Cheilocystidia 20-60 x 5-20 µm, cylindrical, protruding from hymenium, rare to fairly abundant, rarely absent, always mixed with basidia. Pileipellis a cutis with transitions to a trichoderm, made up of cylindrical to inflated hyphae, 5-20 µm wide with slightly to distinctly inflated terminal elements, 30-110 x 5-30 µm. Pigment blue, intracellular in pileipellis. Clamps present.
Habitat: Solitary or in small groups, terrestrial in humus or on fallen branches etc. in deciduous and coniferous forest; also found in Juniperus heaths; Aug.-Nov.
Distribution: Rare but wide-spread all over Europe, from the lowlands up iuta the subalpine zone (-1500 m alt).
