Could be

Won’t be able to distinguish from the pins, shame you can’t revisit the location this year

Based on the habitat and location P. caerulipes is a reasonable guess.

I see caerulipes pins that look like this.

“Could be”

Definitely hardwoods….

I remember cherry, maple, poplar and oak in the area, might have been some birch. Not the kind of place you’d normally find P. ovoideocystidiata. I’d make the trek back up there but I don’t think I’ll have the time to make it again this season.

beech or birch? Why not ovoids? Interesting find this time of year. You gotta go back and get pics of the mature ones!

Could Psilocybe quebecensis…

…be a possibility? After looking at some photos of Psilocybe caerulipes pins I’m a little more skeptical about that name. Guess it’s pretty hard to tell either way.

Good thing is I know exactly where these were growing so maybe next year I can find them again.
