Sel. descr. & figs. - Kühner in Kühn. & Romagn. in Rev. Mycol. 19: 42-43, figs. 10, 11. 1954 (Comps. Fl. anal. 1).
Pileus 8-30 mm, truncately conical or hemispherical, then expanding to convex, slightly to distinctly depressed at centre with slightly inflexed, then straight margin, not hygrophanous, not translucently striate, dark blackish blue or indigo, becoming more brownish when expanded, entirely velutinous to tomentose when young, then pellis breaking up in small adpressed to reflexed squamules, becoming radially fibrillose- subsquamulose at margin, shiny. Lamellae, L = 25-30, 1 = 3-5, moderately crowded, broadly adnate, often slightly emarginate or with decurrent tooth, segmentiform to subventricose, white, then pink with concolorous, entire or fimbriate edge. Stipe 30-60 x l,5-3 (-4) mm, cylindrical or compressed, concolorous with pileus at first, then pallescent to pale blue-grey sometimes with slight violaceous tinge (K. & W. 16E2 then more like 14C2, B2-3) with minute fibrillose-striate covering of darker fibrils, white tomentose at base. Context concolorous with surface in cortex, paler in inner parts. Smell none. Taste none.
Spores 8.0-11.0(-11.5) x 6.0-7.5(-8.0) µm, Q= 1.1-1.6, Q av. = 1.3-1.4, ellipsoid in outline, with 5-7 angles in side-view. Basidia 30-48 x 7.5-14 pm. 4-spored, clampless. Lamella edge sterile. Cheilocystidia 20-60 x 5-12 µm. cylindrical to clavate. Pileipellis a trichoderm at centre. towards margin a cutis, made up of radially arranged 10-18 µm wide, cylindrical to inflated hyphae with clavate, up to 20 µm wide terminal elements. Pigment brownish blue, intracellular in pileipellis. Brilliant granules abundant in pileitrama. Clamp-connections absent.
Habitat & distr. - In small groups among grass in poorly manured semi-natural grassland in coastal dunes and in the 'Fluviatiel district' (Voorne; Drongelens kanaal). Rare in W., N. and C. Europe, from lowlands up into subalpine zone.
