Yellow fieldcap can be found across Europe and North America, with dung patties or heavily-manured fields being its favorite fruiting habitat. The species sometimes goes by the common name Yellow Fieldcap because its young cap sports a bold yellow or golden hue (that color often fades as the mushroom cap matures and flattens). Yellow fieldcap is not know to be edible.
