Coprinopsis radiata, formerly known as Coprinus radiatus, and commonly known as the miniature woolly inky cap,[2] is a coprophilous fungus that grows on herbivore dung.

Coprinopsis radiata was originally published in 1788 as Agaricus radiatus by English naturalist James Bolton.

Samuel Frederick Gray transferred it to Coprinus in his 1821 work A Natural Arrangement of British Plants.

[8] Coprinopsis radiata is successfully cultured on horse dung at room temperature; under these conditions (with no control of external everyday light) the fungus can form a mushroom (mature fruit body).

Chemically, those resembling heterocyclic, unsaturated rings with or without small side groups, such as furfural, activate spores.
