That poisoning thing is my big issue with wild shrooms. Morels are very distinctive and very delicious though.
I have seen dedicated threads etc. and know about shoomery.com, but I always I always think you've got to be really dedicated with all that and it has a really steep learning curve. I also am fairly confident a lot of those people make themselves sick pursuing their hobby. Maybe I'm just a wimp about all that but 'better safe than sorry' I say.
Apparently it is fairly easy to order the spores on-line and setup a simple growing medium to for magic mushrooms that have a lot of that psilocybin, and THAT seems safe. I have also read if you know where a farmer dumps his barn waste or piles of cow shit, that is likely a hot-spot to find shrooms.
