First off this guy is THE authority on all things mushroom in my opinion, second the guy I go mushroom hunting with knows this guy (I have never met him) and thirdly this guy has a club in New York that I keep wanting to join but I hate clubs. I have told my mushroom buddy for two years now 'yeah, yeah I'll send the thing in' one day I might join. I have been into edible wild mushrooms since I was a kid, my grandmother taught me about them, so there is no reason I shouldnt join.
Edit: My grandmother taught me about EDIBLE wild mushrooms not the funny ones. I have not spent a lifetime partaking in mind altering substances - it isnt worth it!
Gary Lincoff knows mushrooms, he is the author of the Audubon book for petes sake, plus many others - there will be a documentary coming out soon - here is an excerpt:
I am in NO WAY promoting 'magic mushrooms' it is just a nice little story.
