Description:Basidiomata clitocyboid or collybioid in stature. Pileus white, several with slight yellowish ochre hues over disc, 17-33 mm diam, convex when young, becoming broadly convex, glabrous; context 2-2.5 mm thick, white. Lamellae buff when young, pink at maturity, adnate, close, 3-4 mm diam, edges fimbriate, becoming eroded with age; lamellulae in numerous tiers. Stipe grayish white, 15-35 mm long, 2-4 mm thick, equal, surface frosted with pubescence, white mycelioid at base. Odor and taste farinaceous.
Macrochemical reactions: 3% KOH no reaction.
Basidiospores 6.6-8.9 x 5.7-7.3 µm (n = 32, Lm = 8 ± 0.54, Wm = 6.7 ± 0.42, Q = 1.0-1.4, Qm = 1.21 ± 0.09), heterodiametric, 5-7 angled in profile view, 4-5 angled in polar view, inamyloid, walls cyanophilic. Basidia (2-) 4-sterigmate, clavate, 25-36 x 8-12 µm. Cheilocystidia hyaline, cylindrical or narrowly ventricose and mostly with a strongly capitate head, 61-101 x 5.6-7.2 µm, capitulum 7-11.3 µm diam. Pleurocystidia absent. Lamellar trama hyaline, hyphae parallel, with inflated and cylindrical cells, 4-40 µm diam. Pileus context hyaline, of radially arranged, inflated or cylindric hyphae, 6-22 µm diam. Pileipellis hyaline, a loosely entangled layer (40-140 µm deep or less than 20 µm in some areas) of cylindrical hyphae, 2-4 µm diam, producing scattered projecting subdiverticulate end cells, repent hyphae making a transition into the context, 4-7.2 µm diam. Stipitipellis a layer of repent cylindric hyphae, 3.2-5.6 µm diam, with slightly thickened walls. Clamp connections present.
