Hysteriaceae, Psiloglonium (?)

Hello all,
Found in Bronx, New York City last weekend on a branch of hardwood. This is most likely something in the Hysteriaceae possibly Psiloglonium. The hysterothecia are relatively large, measuring just over 2mm long. The centrum contains yellowish pigments. Spores are mostly hyaline didymospores, constricted at the septa. But I also see 2 and 3-septate spores as well--plus some with long tails. The spores measure 20-25 x 7-9µm. I was not able to measure mature asci but the immature asci I saw measured 86-104 x 10µm.
Using Eric Boehm's key I arrived at Psiloglonium for genus and then either P. uspallatense (unlikely as it is native to the southern hemisphere) or P. araucanum, which is cosmopolitan, but unfortunately, doesn't resemble my fungus in any other respects. Has anyone seen a Hysterioid fungus with yellow pigments in the centrum and spores similar to mine? Help is always appreciated!
Thanks!
Ethan
