Psilocybe atlantis is a rare psychedelic mushroom which contains psilocybin and psilocin as main active compounds. It is a close relative of Psilocybe mexicana and has been recorded only from Georgia.


The mushroom's hygrophanous cap ranges from 2.5 to 4 cm in diameter, bruising blue where damaged. Its form is conic to convex, smooth to slightly striate, sometimes with a small umbo. The cap surface is pale brown to reddish brown in color. The gills are subadnate, thin and brown. The stipe is 5 cm by .3cm, equal, brownish with small brown scales especially towards the base, bruising blue where damaged. The spore size is about 9 x 6 x 5.5 µm with a broad germ pore. Odor and taste pleasant.

Distribution and habitat

Psilocybe atlantis has been found in grassy lawns and vacant lots in Fulton County, Georgia.
