There are many plants that contain hallucogenic components. One of the most sacred mushrooms employed in divination and other ceremonies is a member of a small genus Panaeolus.
It is known is Mazatec as T-ha -na sa, Shje-to and To-shka. This means the PASTURE MUSHROOM and To-shka means Intoxicating Mushroom It is not as important as species within Psilocybe. This species Panaeolus sphincruinus is used by certain shamans
It has been shown that this mushroom contains the hallucogenic psilocybine . It grows on cow dung found in forests, fields and open fields A very delicate brown yellow mushroom with a darkish stripe and contains gills.
You must have a mushroom guide when trying to find this species. I find it interesting that the European variety of this mushroom contains no psilocybine.
