They appear to be ~ 6 sided..

and that name probably is as good as any at this time.

However, Largent seems to consider it an “extralimital species thus far only reported from Europe”.

They look like a pretty good match to Leptonia nigroviolacea to me, but I don’t know what other options I could consider yet nor am I sure that I am interpreting how many sides these spores have correctly. Anyone else?
