Panaeolus papilionaceus is a "coprophilous" mottlegill type of mushroom. It has a smooth bronze coloured bell-shaped cap (1-5 cm) with a thin, brown stalk (5 mm thick) and dark brown gills. It is found growing in soil that has been enriched with equine or bovine. It is a worldwide species. Identifying features include a black spore print. The gills are mottled grey and black and the tiny white partial veil fragments that hang like little teeth from the edge of the cap. There is an absence of an annulus (ring) on the stalk.
