Cap |
4 to 9cm in diameter, the cap is sepia to dark brown, usually with slightly darker radial streaks. Convex at first and then flattened, it is smooth, with a wrinkled fibrous surface. Beneath the cuticle, the cap flesh is white and firm. |
Gills |
White at first, becoming pale pink, the free gills are broad, crowded and free. |
Spores |
Pale pink. |
Stem |
The stem is 3 to 8cm long and 8 to 12mm in diameter. It is white or pale fawn and of even diameter or very slightly bulbous at the base. The stem flesh is white and firm, and it does not become hollow as it ages. |
Odour/taste |
Not distinctive. |
Habitat |
Solitary or in small groups on stumps, rotting fallen branches and other woody debris of broad-leaf trees; very occasionally on conifer stumps. This species also appears on sawdust heaps. |
Season |
Fruiting through most of the year, provided the weather is mild. Particularly prevalent during summer and autumn. |
Occurrence |
Widespread and very common. |
Similar species |
Pluteus cervinus does not have a wrinkled cap and is generally rather larger. |
