More than a hundred stone sculptures with an unmistakable mushroom shape, some almost three thousand years old, are distributed among private collections, museums, and archaeological excavations in Mexico, Guatemala, and El Salvador. No one disputes their form. What has been debated for decades is what they truly meant to those who carved them.
A catalog that has been growing since 1957
Archaeologist Stephan de Borhegyi was a pioneer in systematically cataloging these objects, documenting in 1957 a chronological map with up to 50 archaeological sites where mushroom stones and ceramics with the same shape had been found. Decades later, botanist Bernard Lowy substantially expanded the record with new findings in Guatemala, arguing that these sculptures were likely associated with religious ceremonies in which hallucinogenic mushrooms played a central role, possibly linked to fertility cults.
Mushrooms, not vases
The interpretation has not been uniform. Anthropologist Ulrich Köhler proposed an alternative reading in 1976: that many of these pieces were actually potter's tools, not ritual objects. The debate illustrates a recurring problem in the archaeology of the symbolic — separating form from function requires more than visual resemblance. Even so, the accumulated weight of findings, coincident iconography in Mayan codices, and ethnographic records of local legends about mushrooms and lightning have swayed most specialists toward a ritual interpretation.
A chronology extending to the Classic period
Mushroom stones are concentrated in the Guatemalan highlands and the Pacific slopes, with a chronology spanning from the Late Preclassic to the Protoclassic period. Combined with late mentions in colonial codices and oral traditions documented among Tzʼutujil people and other contemporary Mayan groups, they constitute one of the most extensive sets of material evidence on the ritual use of mushrooms in any region of the ancient world.
