Pileus 5-15 mm diam., subglobose to convex finally expanded with a reflexed margin; surface initially cinnamon becoming paler towards the apex but retaining numerous small, innate, brown squamules, somewhat viscid. Lamellae adnexed, pale yellowish-brown, narrow, up to 2 mm wide, moderately crowded, with lamellulae of three lengths; edge concolorous. Stipe 8-15 x 1-3 mm, short, cylindric, fistulose, white, smooth, glabrous. Veil cortinoid, present only in the early stages, brown. Context up to 1-5 mm thick at the disk, whitish, firm fleshy, of thin-walled hyaline hyphae, 2-6 Mm diam., with clamp-connexions. Spores 6-8.5 x 4.2-5.2 (7 +/- 0.58 x 4.7 +/- 0.35) um, Q= 1.51, ovoid to ellipsoid, smooth, with a ferruginous, thickened wall, and a small germpore which scarcely truncates the apex. Basidia 15-18 x 5-6 um, short clavate, bearing four sterigmata, up to 3.5 um long. Lamella-edge sterile, with crowded cheilocystidia. Cheilocystidia 23-28 x 8-12 um, ovoid, short fusoid to inflated utriform, hyaline, thin-walled. Pleurocystidia 38-45 x 8-11 um, lageniform, with a cylindric neck, 4.5-6 thin-walled. Hymenophoral trama regular, hyaline to pale brown, with parallel hyphae similar to those of the context. Pileipellis a disrupted epicutis, of repent, parallel hyphae, uninflated, 4-9 um diam., loosely arranged, heavily encrusted with a brown pigment, embedded in a gelatinous matrix. Fig. 17A-E, p. 879.
