Description:Basidiocarps gregarious. Pileus 4–8 mm broad, hemispherical, later hemispherical to convex with plane centre and involute then inflexed margin, finely tomentose, smooth or shallowly rugulose and/or shortly striate-sulcate at margin, dark (grey-)brown with paler margin when young, then brownish at centre and paler, beige to pale brown at margin. Lamellae moderately close to distant, L = 10–16, l = 2, adnate or with a very small tooth, white to pale cream also in old basidiocarps, with concolorous, finely pubescent edge. Stipe long and slender, up to 40 × 0.5 mm long, filiform, insititious, smooth, glabrous, dark brown to black-brown with paler, at first ± concolorous with lamellae, then brownish apex. Context membranaceous, with bitter taste. Basidiospores (7.7–)8.5–9.5(–10) × 4.0–5.0 μm, average 8.8 × 4.4 μm, E = 1.88–2.25, Q = 2.0, ellipsoid, ellipsoid-fusoid, smooth, hyaline, thin-walled. Basidia 26–27 × 8.0 μm, 2-spored, clavate. Basidioles up to 31 × 4.0–8.0 μm, clavate or fusoid. Cheilocystidia 20–31 × 11–13 μm, broadly clavate or pyriform, smooth, thin-walled. Pleurocystidia absent. Pileipellis a cutis composed of cylindrical, slightly thick-walled, ± smooth or diverticulate, smooth or incrusted (zebroid), up to 8.0 μm wide hyphae mixed with scattered, clavate or irregular, coralloid or broom cells of the Siccus-type. Pileocystidia absent. Stipitipellis a cutis of cylindrical, parallel, slightly thick-walled, incrusted, up to 4.0 μm wide hyphae. Caulocystidia absent. Clamp connections absent in all tissues. Chemical reactions. Stipitipellis and stipe medulla hyphae dextrinoid, other tissues and basidiospores non-dextrinoid.
