So those white speckled red mushrooms of mario bros and world of warcraft fame have a name. They do exist! they're called Fly Agaria. The greek soldiers used to take this mild hallucinogen prior to entering battle to get something called "bear shirts" - or as we know it today, Berserk. They'd take these mushrooms, and go batshit crazy on the battlefield, ripping through sheilds like animals and completely demoralizing the enemy forces.
