A very variable and common woodland mushroom, which is a shame as although edible it has a poor taste.
|Common Names||Butter Cap, Buttery Collybia (US)|
|Scientific Name||Rhodocollybia butyraceae.|
|Average Mushroom height (CM)||6|
|Average Cap width (CM)||5|
The cap varies greatly in shape and colour as the mushroom matures. It starts convex with an umbo and can be almost black and as it matures the cap generally gets lighter from the edges but always maintaining an darker umbo, when very mature the edges of the cap can turn upwards. The cap has a buttery or greasy feel to it.
White, sometimes off white, crowded and usually free of the stem, sometimes joined narrowly or adnexed.
The stem tapers towards the top and can be off white to cream sometimes with a red to brown base.
Taste / Smell
White to off white to pale pink. Ellipsoid.
An almost annoying mushroom to find as they are very common throughout late summer onwards and aren’t a particularly good edible.
Until recently, it was often referred as Greasy Toughshank (Collybia butyracea).
