Panaeolus cinctulus

Banded mottlegill

A cosmopolitan small brown mushroom of compost heaps, fertilised lawns and gardens, and a historic weed in commercial Agaricus beds. It contains psilocybin, so growing it is illegal in many places; check local law. It fruits readily on rich compost from spring to autumn after rain.
