The cap is 2 to 10 centimetres (34 to 4 in) across. It is convex and becomes broadly convex or almost flat. When fresh, this species is smooth and moist. It has a reddish-brown colour fading to cinnamon. [5]

The gills are either free from the stem, or narrowly attached. They range from close to crowded and are whitish. [4] Occasionally, they develop a pinkish tone as they age, and often form fine, jagged edges.

The stem is up to 10 cm long and 1 cm thick. It is normally somewhat club-shaped. [4] It can either be moist or dry.

The flesh of this species is white. There is no distinctive odor or taste.

The spores are pale yellowish, pale pinkish, or white. [5]
