spore 8um long
is this angiosperm wood or bark?
my guess is Encoelia glauca. This species is difficult to characterize. It has a granular yellowish matter in the excipulum, faintly amyloid apical rings of asci, and lacks a ionomidotic reaction.
I am unaware of American records.
Maybe the spores of your sample are different. European E. glauca has rather narrow spores with some droplets.

It was on wood without bark
Here is a photo of it with Lugols.
The fungus has also an anamorph (aggregated pycnidia) of a similar colour, but it seems yours is devoid of it.
Your guess of a Chlorociboria is not too bad indeed, it is actually the relationship that the molecular data from European material suggest.
I have written to Kadri Pärtel about your collection, and she is actually interested in gaining a sequence from it to compare with her European data. The result would indeed be interesting, one never knows how wide a species is distributed, or whether different taxa exist.
Did you keep a herbarium specimen of this and would you be willing to send a part to her? She is working at an estonian university on encoelioid fungi since quite a few years.

I kept herbarium specimens, the entire collection in the photo. I am willing to send them to her. Where should I send them?
Thank you,
John
