Saprobic. Found along roadsides, grass, disturbed ground. Cultivated in China. Coprine, which has unpleasant consequences if consumed with alcohol, is found in Coprinopsis atramentaria, but not Coprinus comatus. Coprinus comatus has also been found to kill two different nematode species! Coprinus comatus is more closely related to Agaricus and Lepiota than it is to the other dark-spored, ink producing, deliquesing mushrooms like Coprinopsis atramentaria and Coprinellus micaeus! 032-001
