The Huautla mushroom, also known as Psilocybe cubensis Huautla or simply Huautla, is a species of psychedelic mushroom native to the Sierra Mazateca region of Mexico. It is named after the town of Huautla de Jiménez, which is known for its use of entheogenic mushrooms in traditional indigenous rituals.

Huautla mushrooms are small and brownish in color, with a distinctive conical cap and a thick stem. They contain psilocybin and psilocin, which are psychoactive compounds that can produce profound changes in perception, mood, and consciousness. When ingested, the effects of Huautla mushrooms typically last between 4-6 hours and may include altered sensory perception, synesthesia, mystical experiences, and a sense of interconnectedness with nature and the universe.

Huautla mushrooms have been used for centuries by indigenous communities in the region for medicinal, spiritual, and recreational purposes. They gained wider recognition in the West during the 1950s and 1960s as part of the psychedelic counterculture, and have since become a popular subject of scientific and cultural inquiry.
