This fungal family comprises many important decomposers which survive on dead wood, mulch, leaf litter, and logs. More often than not, these fungi can be seen growing in grassy areas or fields and are generally feeding off of surrounding plant roots and debris. The mushrooms in this group generally have dark/black spore prints. The overall shapes and sizes of mushrooms in this family can vary widely and can range from round puffball type mushrooms to a standard cap and stem type mushroom.
The fungi in the genus Coprinus are most commonly seen growing in grassy parks or in mulched areas. They have black spore prints and the mushroom bodies will melt away (deliquesce) rapidly. This deliquescing process allows the fungus to spread its spores as they are exposed to the air and released. These often grow in groups and are predominant in the summer and fall seasons. The overall mushroom shape includes a stem with a tall white (sometimes flecked with brown) concave cap which covers the stem until it is mature.

DO NOT EAT WILD MUSHROOMS WITHOUT IDENTIFICATION BY AN EXPERT. THESE ARE ONLY IDENTIFIED TO THE LEVEL OF GENUS AND ARE THEREFORE INADEQUATE TO DETERMINE EDIBILITY. EATING WILD MUSHROOMS CAN KILL.
