I think (I could be wrong) that the bad ones won't necessarily make you trip,
I think they pretty much would have to have Psilocybe or however you spell
it. Since we're on this subject, I didn't realize it could take 2 weeks but that
makes sense. When I was 14 or 15 I remember going down and trying
mushrooms that I found at my friends farm on some horse shit. I think
they grow well on cow manure but not horse perhaps? So since those
shrooms didn't work, I went on a voyage and collected all sorts of crazy
looking shrooms throughout the forest. Some were growing off of rotten
wood, some were growing off of the ground, some were growing near the
flooded ground, etc. I took them all and put them on a pizza and ate the
pizza. I felt nothing at all. But it does make me think about how I could've
eaten a bad one or two. Sheesh, what a dumb thing to do.
