There are many different hallucinogenic mushrooms, some more potent then others. If you serious about going shroom hunting please please at least READ up on the subject, and take someone who knows what they are doing with you. Death is pretty permanent (from my understanding).
I would kill to get my hands on one of those lovely little red suckers (Amacita Muscaria, Fly Agaric). I really cant believe how many people are saying theyve never seen those?! I remember seeing them EVERYWHERE mainly as a kid, in picture books and cartoons. Remember the little dancing mushrooms in fantasia?? those were so sweet.
