The butter Rübling found from June to November in coniferous and deciduous forests on poor soils. It is widely distributed in Europe and North America. Other natural resources should exist in East Africa.
System
The species was first described first in 1792 by Jean Baptiste Francois butyraceus Bulliard as Agaricus and assigned to the genus of mushrooms (Agaricus ). In 1871, Ferdinand Kummer realized that it was not a mushroom and ordered the mushroom is the genus of the Velvet foot ( Collybia ) to. Only in 1979 the way then by Joanne Williams Lennox in the genre of Rosasporrüblinge ( Rhodocollybia ) has been asked and got her today valid name Rhodocollybia butyracea.
