Description:Entoloma triste (Velen.) Noordel.
Icon.: Noordel. & Wölfel in À–sterr. Z. Pilzk. 6: pl. IIa. 1997.
Bibl.: Noordel. & Wölfel in À–sterr. Z. Pilzk. 6: 27-28. 1997.
Pileus 10-35 mm broad, conical at first, then expanding to conico-convex or convex to almost applanate, always with small umbo, when old also concave with reflexed margin, hygrophanous, not or rarely slightly translucently striate at margin only, very dark grey-brown to blackish brown, pallescent along radial streaks to mouse-grey or brownish grey, glabrous or finely plush-tomentose at centre. Lamellae normally distant to distant, deeply emarginate-adnate, ventricose, dark beige-grey when young, then with pink tinge, often transvenose with concolourous, entire edge. Stipe 10-45 x 1-4 (-5) mm, cylindrical or with broadened base, rarely compressed with groove, dark horn-grey with paler, browner apex, glabrous or slightly striate with fine, longitudinal fibrils, fistulose; white with abundant white tomentum. Smell and taste weak to farinaceous, quickly disappearing.
Spores 8.5-11 (-13.5) x 6.0-8.0 (-9.0), Q = 1.2-1.9, very variably shaped, heterodiametrical, from 5-7 angled to 6-10 angled in side-view. Basidia 27-52 x 9-13 µm, 4-spored, clamped. Lamella edge fertile. Cystidia absent. Hymenophoral trama regular, made up of thin-walled, cylindrical to fusiform elements, 8-25 µm wide. Pileipellis a cutis at margin of 4-8 µm wide, cylindrical hyphae, at centre often passing into a trichoderm of inflated terminal elements, up to 25 µm wide, rarely the entire pileus is a simple cutis. Pigment dark brown, purely intracellular. Clamp-connections restricted to the hymenium.
Habitat and distribution: terrestrial, usually in mossy places in heaths, edges of woods and paths, on light, acid to neutral rarely slightly calcareous soil, May-Oct. Widespread all over Europe but rare.
