Taxonomy
First described as Agaricus domesticus by James Bolton in 1788, it was later known as Coprinus domesticus before it was transferred to the genus Coprinellus in 2001.[4]
Description
The cap is yellowish, thin and grooved, grows up to 5 centimetres (2 in) tall prior in a shape resembling a closed umbrella before expanding[2] to nearly flat. The gills are adnexed, close, and whitish before darkening. The stem is up to 10 cm (4 in) long and 8 millimetres (3⁄8 in) wide. The spore print is black.[5]
The firerug inkcap gets its name from the bright orange carpet of hyphae grown around the mushroom.[6] The covering is known as an ozonium, which resembles an aboveground mycelium.[6] The ozonium is not always present and can also grow in the absence of any mushrooms.[7]
Spores are 6-9 x 3.5-5 µm, elliptical, smooth, with an eccentric pore. Basidia are 4-spored; surrounded by 4-6 brachybasidia. Pleurocystidia are subglobose to subcylindric; up to 120 x 65 µm. Cheilocystidia variously shaped; up to 100 x 60 µm.[6]

Similar species
Coprinellus radians is identical in every aspect except for its larger spore size.[7] These are the only two species that are known to form this ozonium.[7]
Microscopy may be required to distinguish related species in the group.[5]
Habitat and distribution
The species is saprophyte, growing gregariously or in small clusters (occasionally alone) on decaying hardwood logs.[6]
It is present worldwide. It grows on hardwood stumps, logs, and debris in North America from May to September in the East and November to April near the West Coast.[5]
Uses
Although it is difficult to identify, it has been said to be edible.[2]
