Mazatapec
Psilocybe cubensis
Named for the Sierra Mazateca of Oaxaca, home to the Mazatec people and the ceremonial tradition that reached international attention after R. Gordon Wasson's 1957 account of a velada with curandera María Sabina. The variety sold under this name today is a hobbyist stabilization tied to that regional reputation — not a mushroom sourced from those ceremonies, and the direct chain of custody is undocumented.
Often lumped in with other Mexican-labelled varieties such as Oaxacan, since regional-name lines share modest morphology and rest on unverifiable origin claims rather than confirmed genetics.
Deadly species grow in the same places as psilocybin ones and can resemble them closely. Never eat a wild mushroom identified from a website — including this one.
