Cap 10-30 mm across, conical to convex-campanulate, translucent-striate near the margin, pruinose, glabrescent, cream to somewhat yellowish white, the margin usually purer white, but also said to be more yellow. Odour none when fresh, of iodoform on drying out. Gills 18-34 reaching the stem, ascending, narrowly adnate, decurrent with a short tooth, white, turning yellowish pink in the herbarium. Stem 30-70 x 1.5-2.2 mm, hollow, equal, straight, curved below, smooth, glabrous, watery white, at the base covered with fibrils. Basidia 25-29 x 6-8 µm, clavate, 4-spored. Spores 8-9(-10) x 4.5-5.2 µm, Q=1.5-2, Qav ˜ 1.7, pip-shaped, smooth, amyloid. Cheilocystidia 15-35 x 7-19.5 µm wide, forming a sterile band, clavate to obpyriform, covered with comparatively few, fairly evenly spaced, straight or somewhat curved, cylindrical excrescences, some of which are apically capitate, 1-6 x 1-1.5 µm. Pleurocystidia absent. Lamellar trama dextrinoid. Hyphae of the pileipellis 2-3.5 µm wide, somewhat gelatinized and forming dense masses, densely diverticulate, excrescences 1-2 x 0.5-1 µm, frequently also covered by small, almost globose cells 4-9 µm wide. Hyphae of the cortical layer of the stem 1.5-5 µm wide, not very densely covered with short, fine excrescences. Clamps present in all tissues.
