Mushrooms from the genus Psilocybe can provoke psychedelic experiences thanks to compounds including psilocybin.

A new study finds that within another genus of “magic” mushrooms, psilocybin is synthesized using a completely different chemical pathway. https://scim.ag/47hEBv1

In mind-bending twist, ‘magic’ mushrooms evolved twice independently

Study identifies entirely new suite of enzymes that can make psilocybin
