on a serious basis I wouldn't eat anything that you've picked yourself unless you're qualified in the field; too many mushrooms are toxic, and some can seriously poison you, besides which, messing around with psychotropic substances isn't necessarily a very good idea (as I've posted in other threads on the subject by people who are fairly blasé about such and think it's all great) as some of the compounds chemically interact with your brain (like LSD) and once they're in there you're not getting them out.
when I was working at the toxicology research lab one of the researchers warned me before I left to go to university that if I was going to do any drugs, not to touch LSD for this very reason; heroin, cannabis, speed not so worrying as they're not 'forever', but LSD reacts with your brain and causes permanent changes.
so, although a lot of people seem pretty ignorant about a lot of stuff, out of respect for your head you might think twice about the possible effects of doing certain things - besides, there are plenty of fantastic ways of getting off without having to resort to eating fungi; I've never been a big fan of 'em, even on pizza. Anchovies rule!!
