Psilocybe atlantis is a rare psychedelic mushroom that 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. Below it mentions that P. atlantis was recorded in Arkansas...(?)

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[edit]

Psilocybe atlantis has been found in grassy lawns and vacant lots in Fulton County, Georgia. It has also been reported in forested areas grazed by cows and sheep in Central Arkansas. Also been found in Cherokee county. (

The original find was made in Fulton County Georgia, growing in a patch of moss beside a 5 year old home whose lot bordered a wooded area within 50 meters of a tributary of the Chattahoochee river.
