Originally found only in Morocco, Africa, and then Hawaii, Panaeolus Bisporus is amongst the most rare psilocybin containing species in the world. They prefer the dung of buffalo and cattle, but can also be found growing in manure rich lawns. Microscopic feautures: Spores black in deposit, 12-14 x 8-10. x 6-7.5 microns. elliptical. Thanks to the work of Alan Rockefeller and PMG, we have the pleasure of being one of the only vendors offering these spores.
