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.[1] It has a pleasant taste and smell.

While naturally rare it is often cultivated for its psychedelic properties.


The cap is 2.5–4 cm in diameter, conic to convex, and smooth to slightly striate, sometimes with a small umbo. The cap surface is pale brown to reddish brown in color, hygrophanous, and bruises blue where damaged.
Its gills are subadnate, thin, and brown.
The stipe is 5 cm by .3 cm. It has an equal structure and is brownish with small brown scales, especially towards the base. The stipe also bruises blue where damaged.
Psilocybe atlantis spores are 9 x 6 x 5.5 µm with a broad germ pore.

Distribution and habitat

Psilocybe atlantis has been found in grassy lawns and vacant lots in Fulton County, Georgia. Its also been reported in forested areas inhabited by cows and sheep in Central Arkansas.
