damn dude, it sounds like you got some good psionesces (sp?)
the hallucinogen in them isnt psilocybin, its related to it, but its much more potent...damnit, i cant remember the name.
i used to have a book on mushrooms that showed you colored pics and how to tell if they were tripping shrooms or what.
what i do remember though is that they like to grow under cedar trees.
btw, the most ive ever eaten was 1/4 and i took 4 vitamin c pills along with that.
