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
