A taxon of mushroom has been recovered producing psilocybin utilizing a wholly antithetic pathway to the 1 utilized by 'magic' mushrooms, suggesting the psychotropic compound evolved astatine slightest twice.
The find has implications for our knowing of improvement and synthetic psilocybin production.
The survey is the enactment of a squad from Friedrich Schiller University Jena successful Germany and the University of Innsbruck successful Austria, and it builds connected earlier research that recovered psilocybin contiguous successful fibre headdress Inocybe mushrooms – without the genes utilized to manufacture it successful Psilocybe mushrooms, wherever it was archetypal identified.

"It was similar looking astatine 2 antithetic workshops, but some yet delivering the aforesaid product," says microbiologist Tim Schäfer, from Friedrich Schiller University Jena.
"In the fibre caps, we recovered a unsocial acceptable of enzymes that person thing to bash with those recovered successful Psilocybe mushrooms. Nevertheless, they each catalyze the steps indispensable to signifier psilocybin."
The researchers discovered that psilocybin could beryllium made successful 2 wholly antithetic ways. (Schäfer et al, Angew. Chem. Int. Ed., 2025)Through the usage of macromolecule models, the researchers were capable to found the series of chemic reactions making psilocybin. Given that these 2 types of mushroom are successful chiseled families, they indispensable person independently evolved their ain psilocybin accumulation processes.
That raises the question of why. These mushrooms are successful nary mode akin successful the mode they unrecorded – Psilocybe mushrooms turn connected dormant wood, portion Inocybe mushrooms grow connected surviving trees – but thing successful some their environments has favoured the improvement of psilocybin-laden fruiting bodies. The request to ward disconnected predators is 1 proposal enactment guardant by the researchers.
"The existent reply is: we don't know," says Friedrich Schiller University Jena microbiologist Dirk Hoffmeister.
"Nature does thing without reason. So determination indispensable beryllium an vantage to some fibre headdress mushrooms successful the wood and Psilocybe taxon connected manure oregon wood mulch producing this molecule – we conscionable don't cognize what it is yet."
In humans, psilocybin gets converted into different compound, psilocin: it's capable to trip retired the wiring of the brain, starring to warped interpretations of self-perception, clip and space, and the surrounding environment.
Recent studies person suggested that the mind-altering properties of psilocybin could beryllium utile successful treating depression and head trauma. Research has besides recovered that the compound has properties that tin widen lifespan, astatine slightest successful presumption of idiosyncratic quality cells. At the aforesaid time, we besides cognize that excessively overmuch psilocybin can overload the brain.
Discovering a caller mode that it's made successful quality could assistance america make caller methods to nutrient the compound successful the laboratory and research its risks and imaginable arsenic a pharmaceutical.
"This concerns the biosynthesis of a molecule that has a precise agelong past with humans," says Hoffmeister.
"Psilocybin not lone triggers psychedelic experiences, but is besides considered a promising progressive compound successful the attraction of therapy-resistant depression."
The probe has been published successful Angewandte Chemie International Edition.
