Cap initially convex with inrolled margins, then becoming broadly convex or nearly flat. The colour ranges from ochre-brown to red-brown, usually somewhat darker near the centre. Fine brown scales with darker tips cover the cap surfaces. The cap flesh is white and firm. Gills run down the stem or nearly so, closely spaced with frequent short gills. They are whitish, with a tendency to discolour pinkish to brownish. Stem typically club-shaped, often with a swollen base. It is finely lined near the apex and may have a yellow ring zone or occasionally a flimsy white ring with a yellow edge. Above the level of the ring, the stem is pale orange to brown, while below it is whitish or pale pink, becoming greyish-brown at the base. Spore print white.
