Pileus-35 mm diam., conico-convex, campanulate to umbonate-expanded; grey-brown, hazel-brown to dark brown, yellow tints absent; umbo smooth later squamose, fibrillose to rimose towards the margin, often splitting; subviscid when wet, veil remnants absent. Lamellae adnate, adnexed to almost free, crowded (1-7), ventricose; whitish or grey when young turning beige-grey, with white fimbriate edges. Stipe 25-50 x 3-5 mm, cylindrical with marginate bulb (-11 mm diam.); whitish soon turning pink or reddish brown, bulb white outside; pruinate, no veil remnants dry, solid, single in groups. Context brownish in pileus, reddish brown in stipe. Odour not distinctive.
Spores 8-10 x 6-8 µm, nodulose, knobs conspicuous. Basidia 22-30 x 6-8 µm, 4-spored. Cheilo-cystidia 30-45 x 12-18 µm, ovate to subfusoid, metuloid (membrane -4 µm diam.), encrusted, hyaline.

This species is common under Leptospermum scoparium (and probably also L. ericoides) under different ecological conditions. The most distinctive characters are the rather small, metuloid and crystal-bearing cheilo- and pleurocystidia.
