Rhodocollybia butyracea, common name Buttery Collybia,[2][3] is a species of fungus in the Marasmiaceae family of mushrooms.

Description[edit]

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.[4]

The gills are either free from the stem, or narrowly attached. They range from close to crowded and are whitish. 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. 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.[4]

Ecology[edit]

This species is saprobic. It decomposes litter from conifers, usually that of the Pinus genus,[4] and occasionally hardwoods.[5]

Habitat[edit]

Rhodocollybia butyracea is quite widely distributed in North America.[4]

Edibility[edit]

This mushroom is edible, but unsubstantial.
