Diatrypella on Prunus

From NYC, a friend found a small branch of Prunus (Prunus serotina?) with what I think is a Diatrypella emerging from the lenticels in the bark. There are not many well developed beaks. Many of the stroma look flat and deformed. But there are a few stroma with a healthy 10 or 12 beaks emerging. Polysporous. Asci are long stipitate, 183-225 x 13-15µm with the spore bearing part about 55-88µm, IKI-. Spores yellow in aggregate, allantoid, 7-10 (-12) x 1.5-2µm. I am aware that there is a not-very-often-cited Diatrypella prunicola, but it doesn't seem to fit my collection. Is this possibly Diatrypella favacea?
Thank you in advance for your assistance.
Ethan
