Hey, somewhat old post but I thought I'd throw in:
Be careful with the yard Pans, don't eat a bunch of unknowns all at once.
Years ago I ate a good amount of what I identified as P. cinctulus. I'm still quite sure they were all Pans, and they did have jet black spore prints, but I spent 4-5 hours feeling weird, and another 1.5 puking my guts out. No tryptamine buzz delivered.
You can see from
this post that the caps were pretty black to my eye. So I haven't found an accord with this species, although they do appear to be almost everywhere.
On the other hand, I was working on a farm once years ago, and found some large, beautiful Cincts in manure, which is supposed to be a more definitive place for P. cinct instead of P. foe. Those did deliver, actually, with minimal nausea. The only problem was after sampling some I had a very difficult time distinguishing mushroom characteristics to pick more. The mushroom image rose up behind my eyelids, as I had been looking for them all day. Joyous, a "you found us!" feeling. They must be different strains I guess?
