Rumored to have been discovered by John Allen. It hails from the island of Koh Samui, Thailand. As its name suggests, this mushroom was found growing on elephant dung, so it is little wonder that it grows to such an enormous size and potency!

On the other hand, it could be related to a variety of dung-loving psychoactive species commonly found in Thailand such as P. antillarum, Panaeolus Cyanescens aka Blue Meanies, or Pan. tropicalis.
