Coprinus comatus is a typically saprophytic species, that is, it grows and nourishes of decomposing organic matter, both animal and vegetal.

The phenomenon is called deliquescence, according to which a fruiting body, maturing, does not rot like all mushrooms normally do, but transforms into a blackish slurry; this phenomenon always starts from the gills and then extends to the whole cap. Only later on, it will affect also the stem.

This feature makes the mushroom easily identifiable.

Other details are: the numerous scales on the cap, the slender size, the slightly larger stipe at the base and the quick passage from the edible phase to the culinary inconsistency.

The species with the largest size in the genus Coprinus is the Coprinus picaceus, which can reach dimensions even up to 40 cm of length. It is not edible and the smell, which is often repellent, discourages its consumption.
