Psilocybe fimetaria

A small dung-loving Psilocybe of European pastures that fruits on horse or cow dung from September to November. It is uncommon and infrequently recorded, and is one of two Psilocybe species in which psilocybin has sometimes been undetectable. It is still treated as a psilocybin mushroom in many jurisdictions; check local law before cultivating.
