Chaetosphaeria? black pyreno with part spores

Hello all,
I'd love some help with this black carbonaceous pyrenomycete which I found this weekend in New York City. It was found on decorticated hardwood on the ground. The fruiting bodies are uni-peritheciate partly embedded in the wood and around 0.5mm in diameter.
Asci appear very thick walled and in IKI have a darkened ring-like structure at the tip.Â
Spores are 1-septate, brown and frequently break into two part spores at the cell division. They measure 18-20.5 x 4.5-5µm. The part spores measuring about half that.
Can anyone identify this pyreno?
Thanks in advance,
Ethan
