Common Ink Cap

<em>Coprinopsis atramentaria</em>, commonly known as the common ink cap, is a saprotrophic fungus in the family Psathyrellaceae. It is classified as Least Concern on the IUCN Red List, with a distribution spanning Asia (including Taiwan), Europe, and North America. The species typically grows on forest floors, buried wood, stumps, and other decomposing woody substrates in temperate regions. As a saprotroph, it plays an important ecological role in breaking down organic matter. The common ink cap is notable for containing coprine, a compound that inhibits aldehyde dehydrogenase and causes unpleasant reactions when consumed with alcohol. Diet information for this species is not available in current records. Biological traits of this species remain poorly documented in the scientific literature.
