Coprinopsis variegata, commonly known as the scaly ink cap or the feltscale inky cap, is a species of fungus in the family Psathyrellaceae. Coprinus ebulbosus and Coprinus quadrifidus are names assigned by Charles Horton Peck to what he believed were species distinct from C. variegata; they were later shown to represent the same species, and are now synonyms.

It has a medium-sized, bell-shaped to flattened cap up to 7.5 cm (3.0 in) in diameter, with felt-like, patchy scales. The gills, initially white, turn black in maturity and eventually dissolve into a black "ink". Fruit bodies grow in clusters or groups on leaf litter or rotted hardwood, although the wood may be buried, giving the appearance of growing in the soil. The fungus is found in eastern North America. It is not recommended for consumption, and has been shown to cause allergic reactions in susceptible individuals.
