A species of Coprinellus, Also known as Trooping inkcap
The whimsically-titled firerug inkcap is named for one of its more distinctive features. This species usually grows alongside an above-ground, mycelial mat called an "ozonium". With Coprinellus domesticus, the ozonium takes on a fuzzy, orange appearance - thus, "firerug". The species can be found in temperate habitats across much of Europe and parts of North America.
