Abstract

Two populations of the mushroom Psilocybe cubensis (Earle) Singer were studied. The Houston, Texas, type completed its life cycle about seven weeks before the Palenque, Chiapas type from Mexico in vitro. There were reports and observations of toxic reactions from the Texas type. There were no reports of toxic reactions from the Chiapas type although P. cubensis from Oaxaca has been previously reported slightly toxic.
