Brief Description: [See More | Edit]

The stipe-colour of Entoloma griseocyaneum is usually rather pale blue, especially when old, and not as intensely coloured as Bresadola’s illustration suggests. Although this is a rare species, because suitable habitats are rare, it is rather frequently found in suitable habitats, and among the more common species of poorly managed grassland and hayfields. Entoloma griseocyaneum differs from E. anatinum and E. viaregale in having more fleshy basidiocarps, paler colour, and stipe covering. Entoloma coeruleoflocculosum is a smaller taxon with darker colours, simple spore type, blue flocculose stipe, and sterile lamella edge.

Pileus 15-50 mm, conical, campanulate or hemispherical, slightly expanding to convex, with involute then deflexed or straight margin, with subumbonate or blunt, rarely very slightly depressed centre, not hygrophanous, not translucently striate, pale yellow-brown to moderately dark sepia or red-brown, entirely rimose-subtomentose or rimed when young then more distinctly radially fibrillose-squamulose, at centre offen squarrose in old specimens. Lamellae, L = 20-50, l = 3-7, moderately distant to fairly crowded, deeply emarginate to almost free, rarely adnate, segmentiform to ventricose, white then pink with entire, concolorous edge. Stipe (20-)40-120 x (1-)2-6(-8) mm, cylindrical or compressed with groove, often distinctly broadened towards base, pale sky-blue, blue-grey or violaceous, densely silvery striate lengthwise, white or yellow tomentose at base. Context concolorous in cortex, pallid in inner parts. Smell and taste not distinctive.
Spores 9.0-13.5(-14.0) x 6.5-8.0(-9.0) µm, Q = 1.2-1.7, average Q = 1.4-1.5, heterodiametrical, rather irregularly 5-9 angled in side-view. Basidia 4-spored, clampless. Lamella edge fertile. Pileipellis a trichoderm at margin, atrue trichoderm to almost a hymeniderm at centre, made up of inflated terminal elements, 20-80(-120) x 15-40 µm. Pigment intracellular in pileipellis. Clamps absent.
Habitat: in grasslands, preferably on slightly to distinctly calcareous soil, but also frequently found on neutral to acid soil-types, from lowlands up into alpine and arctic environments; summer-autumn.
Distribution: Wide-spread in Europe, rare.
