I don't know much of anything about shroom identification. But I'd suggest you go to http://www.shroomery.org/. There is great info there and you can post it on the boards there, probably with better responses.

BUT, they look nothing like the shrooms I ate when I did 'em once. Were they growing out of grass or shit? (http://en.wikipedia.org/wiki/Shit) I heard that if they are growing out of shit, they are more likely the right ones. :thumbsup:
