Description
The cap is 2 to 10 centimetres (3⁄4 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 flesh of this species is white. There is no distinctive odor or taste.
The spores are pale yellowish, pale pinkish, or white.[5]
