New hallucinogenic mushroom species rewrites fungal history
Summary and headline written by AI from the source article. How we work
Researchers in South Africa and Zimbabwe identified a previously unknown species of hallucinogenic mushroom, Psilocybe ochraceocentrata, closely related to the well-known Psilocybe cubensis.
For years, scientists believed they understood the origins of Psilocybe cubensis, but genetic analysis revealed the two species shared a common ancestor approximately 1.5 million years ago. This discovery alters the understanding of how these psychedelic fungi spread globally. The research team compared specimens found in African grasslands to reference samples stored in scientific collections.
They determined that the African mushrooms represented a distinct evolutionary line, separate from Psilocybe cubensis for over a million years despite their visual similarities in shape, habitat, and preference for dung from grazing animals. This finding challenges a long-held theory that Psilocybe cubensis arrived in the Americas after 1493 with European livestock. Instead, scientists now consider the possibility that large-scale migrations of prehistoric herbivores facilitated the spread of these fungi across continents, using animal waste as a means of dispersal.
The study also clarified the identity of a popular mushroom strain called “Natal super strength,” confirming it belongs to the newly identified Psilocybe ochraceocentrata species. This correction is important because accurate species identification is vital for scientific research, medicine, and legal regulations. The discovery underscores how little is known about fungal biodiversity in Africa, with researchers noting the limited number of documented species compared to the likely total number present.
