Blue meanie mushrooms (Panaeolus cyanescens, formerly Copelandia cyanescens) — also known as “blue meanies” — are a highly potent species of psilocybin mushroom. You will notice, however, that the first part of its scientific name (Panaeolus) is different from other species of magic mushrooms (e.g. Psilocybe cubensis, Psilocybe semilanceata). This is because it belongs to a different genus. Mushrooms from the genus Panaeolus are common, and they grow all over the world in tropical and temperate environments.
Yet while blue meanies do not belong to the genus Psilocybe (as most magic mushrooms do), they still contain the same psychedelic compounds: psilocybin and psilocin. Many users seek out blue meanie mushrooms because they are one of the most potent magic mushrooms, so you don’t need to take as much to achieve desired effects.
