The Dung-Loving Bolbitius (Bolbitius coprophilus) is a widespread gilled mushroom that grows on... (you guessed it) dung! It can also be found on compost, and other nitrogen-rich organic substrates. It grows alone or in groups (singular or gregarious). Its gills are slightly attached to the stem (acutely adnexed). B. coprophilus has a brownish spore print (dull cinnamon brown).
