Pileus 20-32 mm, convex with depressed to umbilicate centre, with involute margin, not or weakly hygrophanous, not or only slightly translucently striate at margin, grey-brown (Mu. 10 YR 3/2-4/2), innately radially fibrillose, at centre tomentose or rugulose. Lamellae, L = 18-36, I = 1-3, moderately distant, adnate to subdecurrent, segmentiform, then ventricose, white, then pink with fimbriate, concolorous edge. Stipe 40-60 x 2-5 mm, cylindrical or attenuated towards base, concolorous with or slightly paler than pileus, flocculose to fibrillose at apex, downwards fibrillose-striate, white tomentose at base, solid or narrowly fistulose. Context concolorous with surface, paler in inner parts. Smell none. Taste not distinctive.
Spores 10.0-14.0 x 8.0-11.5 µm. Q = 1.1-1.5, Q av. = 1.2-1.3, irregularly rectangular to broadly ellipsoid, 5-9-angled in side-view. Basidia 27-55 x 8.5-14 µm, 4-spored, clamped. Lamella edge heterogeneous Cheilocystidia 35-110 x 7.5-23 µm, lageniform with long, tapering neck 3.5-6 µm wide, sometimes with acute apex, always numerous, but mixed with basidia. Pileipellis a cutis at margin, more like a trichoderm at centre, made up of radially arranged inflated 10-25 µm wide hyphae. Pigment intracellular in pileipellis. Clamp-connections present in hymenium.
Habitat & distr.- Terrestrial in deciduous and coniferous forest. Very rare (Groningen: Helpman). Rare in Europe. July-Sept. (Jan.).
