Tiny black bitunicate on Platanus

Ethan Crenson, 11-02-2018 08:21

In the Bronx, New York. Tiny, black, globose, superficial fruiting bodies on a decorticated branch of Platanus × acerifolia. Some appear to collapse into a disc-like form. Asci are bitunicate, 125-148 by 22-27µm, IKI-. Ascospores are golden yellow-brown, somewhat roughened, (4) 5-septate, most constricted at the middle of the spore, bearing a gelatinous sheath, 36-40 by 8.5-10µm. The spores turn blue in iodine. Pseudoparaphyses septate, branched. I believe I posted the same organism on 17 Nov of last year. Any ideas? Thank you!
