La Montaña region, Guerrero

Written in History

In the rugged Montaña of Guerrero, the Me'phaa are among the southern Mexican peoples with recorded ceremonial mushroom use — a case documented lightly in the mycological literature and belonging to the same broad tradition as the Oaxacan veladas.

The Montaña of Guerrero

In the steep, isolated Montaña of Guerrero, the Me’phaa — long known by the outside name Tlapanec — are among the southern Mexican peoples with recorded ceremonial mushroom use. The same species that anchor the Oaxacan veladas, including Psilocybe hoogshagenii, grow through these mountains.

Rain, jaguar, and the Montaña

The Me’phaa hold one of the most intact ritual calendars in Guerrero — a world of rain-petitioning at sacred springs and caves, of offerings to the powers of the mountain, and of specialists who read maize kernels and dream to divine. In the steep, cloud-wrapped Montaña, where the jaguar of the storm still moves through the ceremonial imagination, the sacred mushroom belongs to that same weather-soaked cosmology — a means of asking the mountain what it knows.

In the record

As with the other lesser-documented Mexican peoples, the anchor is Gastón Guzmán’s enumeration of Indigenous groups with recorded ceremonial mushroom practice, which includes the Tlapanec.1 A quiet thread — real, and still largely kept within the community that carries it.

Read alongside

The Me’phaa are set out with their sister peoples in Mexico’s other mushroom peoples.
