The spores are a pretty good match for peckiana.

I have looked at a lot of material that matched peckiana (among the named taxa of sect. Amidella in North America), and the spore size/shape is rather variable.

I’m glad that more collections of this sort are showing up on MO (mostly thanks to you, Ron).

Very best,
