When buying Mexicana A -Strain spores, be aware that they’re considered “active spores” which are for microscopy purposes only. DO NOT CONTACT US ABOUT ANYTHING REGARDING CULTIVATING OR GERMINATING ACTIVE SPORES. 

Shipping is unavailable to California, Idaho, & Georgia. These 3 states strictly prohibit the possession of spores from psilocybin and psilocin producing mushroom species. Orders to these states will be refused and voided. Any payments made for orders to CA, ID, or GA will incur a $5 cancellation fee. 

The provided images are for informational and educational purposes only and should only be used as a reference point. Images and spores are acquired from outside, trusted sources in a legal manner. We do not condone or participate in the cultivation of psilocybin or psilocin producing mushroom species. 

When you buy Mexicana A-Strain syringes, visibility is dependent on the characteristics of the spores themselves. As a result, not all spore syringes will look the same visibly. Despite any visible differences, they are still viable for microscopy research. More information on how we make our spore syringes and possible visible differences, check out our FAQ or blog post How To Make Spore Syringes.

Psilocybe mexicana “A-Strain” Spore Information

Psilocybe mexicana have a rich history that goes back at least 2,000 years. It was a very important part of Aztec culture, specifically. The Psilocybe mexicana mushroom’s main use in their culture was for religious/ceremonial purposes.  In the Aztec language it goes by the name of “Teonanacatl” which translates to “God’s Flesh”. 

Despite its long history, Roger Heim only introduced Psilocybe mexicana to Western society in 1956. Later, Albert Hoffman would run tests on the specimens and subsequently do the first isolation of psilocybin and psilocin in a lab. 

Psilocybe mexicana “A-Strain” especially is in high demand due to its ability to form sclerotia. The A-Strain is able to produce both normal fruits and sclerotia, whereas the B-strain is unable to produce any sclerotia. 

Foil prints of these HEPA Grade Mexicana “A – Strain” spores can be hard to come by because they are in such high demand. The difficulty associated with gathering their spores does not help.  We make it a mission to try and always carry these spores, although supply shortages can still happen. Because of its rich history and rarity, anyone would be lucky to have this unique variety as an addition to their spore library.

Additional information


Subtropical. These mushrooms are known to thrive in subtropical climates places where summers get hot and humid, and the winters are mild. Usually these climates are found between the latitudes of 25 degrees and 35 degrees and the southeast side of all continents.

Research Difficulty



Light Depositor Specimens that typically produce smaller caps and lighter prints, making spore collecting a bit harder but definitely not impossible.
