Durella commutata (?)
Ethan Crenson, 17-03-2019 22:26
Found yesterday in New York City.  Substrate is a large decorticated, fairly-well rotted branch of unknown hardwood.  The cups are about .5mm in diameter and black.  Asci are IKI- measuring about 75-99 x 7.5-9µm. Spores are hyaline, ellipsoid with tapering ends, mostly non-septate, but I saw one 1-septate spore.  They measure (8-) 10-14 x 3.5-4.5µm. Paraphyses are surrounded by brown material, filiform with swollen tips, the tips about 3µm wide.  The closest I could find is Durella commutata. But maybe this is not correct.

Thank you in advance!

Re : Durella commutata (?)
I don't think it is D. commutata, the spores are too large. You should try to see living paraphyses because D. commutata has very conspicuous VBs. The excipulum is a brown porrecta?

Re : Durella commutata (?)
I went back to try to find living paraphyses, but I encountered a problem.  I must have the fruiting bodies of a very similar (macroscopically) species on the same branch.  When I prepared a slide I found microscopic features resembling the Skyttea-like asco with the muriform spores from 21-10-2018

I will create a new forum topic for this new collection.
