A medium to large parasol-like agaric with a shaggy, brown-scaled cap, free gills, and a persistent ring. Flesh typically reddens or orange-browns when cut. Occurs in gardens, woodchip beds, forest edges, and other disturbed habitats.

Cap: 60-180 mm, convex to broadly convex, expanding with age. Surface white to cream, breaking into coarse, brown, shaggy scales, densest at the centre. Scales often erect or fibrillose, giving a rough texture. Flesh white, quickly reddening or orange‑browning when cut or bruised. Margin not striate, sometimes slightly uplifted in age.
Gills: Free, crowded, broad. White, sometimes becoming cream with age. Do not turn green. Edges smooth.
Stipe: 80-180 x 10-20 mm, cylindrical, sometimes slightly bulbous at base. Surface white, bruising orange‑brown. Ring thick, persistent, often double and sometimes movable. Interior soft or hollow in age.
