Psilocybe galindoi, also known as P. galindii, is a Mexican mushroom that is beginning to gain worldwide interest. As a part of the Mexicana family of Psilocybe, it is one of the few species that is capable of producing sclerotia, or “magic truffles”. A sample recently found in Georgia, USA was cloned and is now gaining popularity among amateurs.
Originally suspected to be P. atlantis because of its starchy flavour and ability to form truffles, some characteristics are distinct between the species. They share a similar potency and contain psilocybin as well as psilocin, causing a variable but present bluing reaction to damage and age.
P. galindoi frequently has a small cap (under 2 centimetres) atop a tall (up to 7 centimetres) and slender, but hollow, stipe. The cap is commonly conic or bell-shaped, sometimes presenting with a small umbo or papilla, usually yellowish-brown when wet. When dried, they become a pale straw colour with splotches of blue or black. They can frequently be identified by the long “rhizomorphs”, or root-like structures, near their base.
They are primarily distributed through the Pine-Oak forests of Mexico, or found nearby in rich soils or tall grasses. A preference for high elevations makes Pie de la Cuesta in the state of Jalisco the ideal habitat. From this area, there have been unconfirmed reports of indigenous usage for rituals or ceremonies.
For the same reasons that might have raised indigenous interest, this species has become popular in the form of “magic truffles” or sclerotia. Depending on jurisdiction, truffles may be available in “smart shops” or even online, along with spores to grow them yourself. A popular strain, recently found in Georgia, known as ATL#7, is commonly available and is reportedly easy to grow.
P. galindoi can be grown as either truffles or mushrooms, the latter having a difficulty of cultivation on par with P. cubensis. Anecdotes suggest that the species grows very quickly and is efficient given its potency. Given its nature to form sclerotia, this is one of the few species than can still be readily purchased for consumption in certain countries.
