Pileus 15-30 mm, conico-convex, then expanding to convex or applanate, not too distinctly depressed at centre with slightly involute or straight margin, hygrophanous, when moist translucently striate up to half of radius, creamy white to pale yellowish pink or isabella (Mu. 2.5 Y 7/4, 8/4), especially at centre, pallescent on drying, glabrous, radially fibrillose, sometimes zonate when dry, shiny. Lamellae, L. = 15-22, I = (1-)3-5(-9), distant. adnate to deeply emarginate or with decurrent tooth. white, then pink with entire, concolorous edge. Stipe 20-55 x 1.5-3 mm, cylindrical or tapering downwards, white to cream or slightly pinkish-yellowish at base, hyalinous, glabrous or with fine, adpressed silvery striation, sometimes white pruinose at apex, usually narrowly fistulose. Context very thin, white-hyaline. Smell none. Taste none.
Spores 8.0-11.5 x 6.0-8.0 µm, Q = 1.1 -1.7, Q av. = 1.35, 5-6-angled in side-view. Basidia 30-47 x 10-12.5 µm, 4-, rarely also 2-spored, clamped. Lamella edge fertile. Cystidia absent. Pileipellis a cutis of entangled cylindrical hyphae 10-15 µm wide, more like a trichoderm at centre with ascending cylindrico-clavate up to 25 µm wide terminal elements. Pigment almost absent, pale intracellular. Clamp-connections present in all tissues.
