Durella commutata (?)

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.
