General Description:

Coprinus comatus is a well-known and relatively easily recognized mushroom with gills that “deliquesce” or turn into a black “ink” with age. Found growing alone, scattered, in lines, or in clusters or fairy rings. Saprobic. Pileus 5-14 cm long, 3-5 cm wide; oval to cylindrical when young, becoming broadly conic (5-8 cm) to nearly plane with age. White to whitish with a brownish central disc at apex. Large shaggy scales. Flesh thin; white; soft; fibrous. Gills free; very crowded; very narrow; white, becoming pinkish and eventually black, then turning into a black “ink” from the margin upward. Stipe 5-20 cm long; 1-2 cm thick; smooth; white; hollow; slightly bulbose base.

Basidiospores 9-13 × 7-9 micrometers in size; ellipitcal; smooth with an apical pore. Spore print black.

Diagnostic Description:

DNA studies show that Coprinus comatus is a fairly close relative of Agaricus and Lepiota.


Distribution:

Coprinus comatus is widely distributed in North America and is also found in Europe. Found in the Rocky Mountains.


Habitat:

Saprobic, growing alone, scattered, or in clusters, lines or fairy rings. Found in grassy areas, lawns, on soil, in wood chips, or on hard-packed ground such as along roadsides and other urban sites. Found in areas where the soil has been disturbed. Fruits during the spring,summer, and fall, typically


Look Alikes:

Other Coprinus species, which include Coprinus colosseus and Coprinopsis atramentaria. C. colosseus is found in the Pacific Northwest and has a stem up to 50 cm in length. C. atramentaria is a related inky cap that is similar looking, but has a smooth cap instead of scales, and also lacks the elongated shape.


Uses:

Considered to be a delicious edible when young in the button stage. One of Clyde Christensen’s “Foolproof Four,” four species of mushrooms that can’t be confused with poisonous ones.
