Panaeolus bisporus

A small, black-spored Panaeolus of the former genus Copelandia that grows on dung and grassy ground, told apart from its relatives by two-spored basidia. Like other Copelandia it is reported to contain psilocybin, which is a controlled substance in many countries; check local law before culturing it.
