Panaeolus cyanescens, also known as Copelandia cyanescens and blue meanies are a hallucinogenic mushroom that contains psilocybin, serotonin, and urea. [1]


The cap is 3.5 cm across, hemispheric to convex, and incurved when young. Tan at first, becoming light gray in age. The gills are adnexed and close, gray to black. The stem is 8 to 12 cm long and 1 to 3 cm thick and pale yellow, staining blue where bruised. This mushroom is very similar to Panaeolus tropicalis.

Habitat and Distribution

Panaeolus cyanescens is a coprophiliac (dung-inhabiting) species which grows in tropical and neotropical areas in both hemispheres. It has been reported in Hawaii, Louisiana, Florida, Australia, India, Mexico, Bolivia, the Philippines, Thailand, France, and Brazil, and is probably more widely distributed.
