Could this be a species of Phaeocryptopus? P. nudus has been reported on this host before, but I cannot find much info on it. The tree was experiencing a needle cast of last years growth, Fabrella tsugae was also found on the same branch. No amyloid reaction in Lugols. All micro taken in H2O. Spores measure 8-10 x 4-5 um.
Location: Cranberry Wilderness, West Virginia, USA
Host: Tsuga canadensis
Thanks!

Re : Phaeocryptopus?
Looking closer the ascomata do not appear to be erupting from the stomata. But the bitunicate asci and spores look promising for Venturiaceae.
