Description: Coprinopsis atramentaria, is commonly known as the common ink cap, inky cap or alcohol inky cap. It is a medium-sized conical agaric, that is greyish-brownish, later blackening and dissolves itself in a black ink-like liquid at maturity. It grows generally in tufts, in fields, gardens and waste ground, near broad-leaf tree stumps or buried wood.

Cap egg-shaped when young, expanding to become conical-convex with age. The colour is grey to grey-brown. The flesh is white in young specimens but soon discolours and deliquesces slowly from the margin, fairly thin in relation to size and fragile. Gills attached to the stem or free from it, crowded, whitish, becoming black. Stem white and smooth, with fine reddish-brown fibrils at the base and hollow inside. Spore print black.
