ornamented mushroom

A small Agaricus described by Elias Fries in 1838, recorded widely across Europe, especially Britain, Sweden and Belgium. Like its larger relatives it lives on humus-rich soil and litter; the fruiting conditions here come from the measured climate and general Agaricus cultivation.
