For over a decade now, researchers have wondered why magic mushrooms go blue when cut. Magic mushrooms are one of the many species that can generate a deep blue coloration when cut, and this phenomenon was puzzling to many researchers until recently. Thankfully, researchers have now investigated the mushroom Psilocybe cubensis and discovered an enzyme that they named PsiP. When a mushroom is bruised or sliced, PsiP cuts off the phosphorus-containing portion of the psilocybin molecule, freeing the psychoactive molecule psilocin. Thanks to the recent advancements, we now know a little more about a characteristic that has kept scientists baffled for some time now.
