Hello all,
Found recently in New York City on the stem of an oak leaf. There was only one fruiting body so I didn't have much to work with. It appears to be a dark, velvety brown stipitate ascomata with a fringe of light colored hairs at the margin.
Spores are reniform, the bend in the spore in the last 1/3 of its length, 12-14.5 x 5.5-6.3µm. Asci with croziers, about 112 x 13µm, IKI+. There are a profusion of brown paraphyses which are septate and about 3µm in width.
The spore morphology resembles what i have seen for Rutstroemia sydowiana, but the colors of the apothecium are far more dark than the images I have seen of that taxon.
Any help would be appreciated.
Ethan

Hello Ethan!
Looks like Rutstroemia sydowiana when old.
