In addition to decaying wood, this strain also grows in pig dung in Europe, South America, Australia, and New Zealand A chemical analysis by Jochen Gartz in 1993 found G. purpuratus contains 0.34% psilocybin, 0.29% psilocin, and 0.05% baeocystin.

Psilocybe paulensis (Guzmán & Bononi) Guzmán (= Psilocybe banderiliensis var. paulensis Guzmán & Bononi) This is the species in which the alkaloid known as baeocystin was first discovered. However, the story behind its discovery is a bit tragic.

More than 180 psilocybin-containing mushrooms species are found all over the world and can induce hallucinogenic/psychedelic effects when consumed. Psilocybin is converted by the body to psilocin, and this is the actual compound which produces their psychoactive effects. Additional chemicals commonly present in minor amounts include baeocystin and norbaeocystin, although the extent to which these contribute to the overall effects is unclear.

The danger of purchasing any kind of magic mushrooms (fresh or dried) is that, unless you’re an expert, you will not know exactly which strain you’re purchasing. There are many different types of psilocybe mushrooms and some are stronger than others. Consuming a dose you believe to be a weak strain may bring about unexpected and unpleasant effects if turns out to be a different or a stronger variety. Found all over the Eastern United States, this species turns a greenish blue when bruised. You can find them on oak stumps between August to November. Gymnopilus luteoviridis Gymnopilus liquiritiae

Psilocybe semilanceata is very common in the wild but notoriously difficult to cultivate both indoors and outdoors. It’s also listed by Paul Stamets as the third most potent species of Psilocybe mushrooms. Illinois — Psilocybe silvatica, Gymnopilus sp., Inocybe insignis, Panaeolus cinctulus, Gymnopilus brandlei, Pluteus americanus, Gymnopilus luteusExpert mycologists believe the poisoning wasn’t the result of the Psilocybe mushrooms but rather a common look-alike such as a species of Galerina or Amanita. Liberty Caps grow most abundantly in open fields and pastures, but can also be found in wooded areas near small towns or cities. This species is extremely common —found naturally on all continents short of Antarctica. They’re also the easiest species to cultivate, produce high yields, and are notably potent. These mushrooms can also be found in New Zealand and South Africa and just about everywhere in between (albeit less common than North America and Europe).
