Psilocybe brasiliensis

The Brazil Strain, also known as Psilocybe brasiliensis, is a species of psilocybin-producing mushroom native to Brazil which has yet to be reported growing elsewhere.
This exotic strain was first documented in 1983 by Mexican mycologist and anthropologist Gastón Guzmán Huerta, who considered his find to be a neurotropic because of the active bluish bruising of the flesh. This phenomenon is commonly related to the presence of the psychoactive alkaloid psilocin, though, still to this day, experts seem to debate on that theory.

With a general shape resembling some of the temperate Psilocybes like P. cyanofibrillosa, P. brasiliensis is said to also have a special link to P. aztecorum, P. baeocystis and P.mexicana.

Like many magic mushrooms growing naturally, the Brazil Strain is an ancient strain consumed by Mesoamericans for generations, and considered sacred medicine.

Because it is a grassland species, the Brazil Strain is probably more widespread than currently said to be. Even if it is not much documented by contemporary mycologists, the specie is known to still grow naturally in northern parts of Brazil, and rumours have it that Brazilians and travellers alike seek this tropical cubensis for its spiritual and visual enhancing powers.
Surely, if the species was legal and if more Brazilians were aware of its existence, its range of dominion would be better documented. Nonetheless, the Brazil Strain magic mushroom strain is cultivated in vitro worldwide.

With no doubt, the Brazil Strain is a fast growing psilocybin-containing variety, a great candidate for cultivation in tropical environments, and like any Psilocybe cubensis, an easy-going and generous fruiter.
