Lamellae, adnate, ventricose, moderately crowded, moderately thick, up to 3 mm broad, white becoming purely pink, with pale pinkish brown or more rarely concolorous edge, with 3 tiers of lamellulae. Stipe 40–60 — 1–2 mm, equal, cylindrical, fragile, hyaline, paler than pileus, whitish to very pale brown, glabrous, polished, with white basal mycelium. Context thin, submembranous. Odour not distinct. Taste not distinct.
Spores 9.5–13 — 7.5–9 µm, heterodiametric, mostly 6–9-angled in side-view with pronounced angles, thick-walled. Basidia 28–35 — 9–10 µm, clavate, 2–4-spored, rarely 1 or 4-spored, sterigma up to 2 µm wide, clampless. Lamellar trama regular of cylindrical elements. Lamellar edge sterile or heterogeneous. Cheilocystidia 40–70 — 7–10 µm, clavate, hyaline, nearly colorless, thin-walled. Pleurocystidia absent. Pileipellis a cutis with a transition to a trichoderm at center, terminal elements up to 15 µm wide. Pileitrama regular, made up of cylindrical hyphae to 20 µm wide.
