Rhodocollybia butyracea, common name Buttery Collybia,[2][3] is a species of fungus in the mushroom family Omphalotaceae. It has a number of subspecies.[4]
The cap of this mushroom is 2 to 10 cm 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]
This species is saprobic. It decomposes litter from conifers, usually that of the genus Pinus,[5] and occasionally hardwoods.[6]
Rhodocollybia butyracea is quite widely distributed in North America.[5]
This mushroom is edible, but unsubstantial.[7]
Similar species include Gymnopus dryophilus.[4]
