Ionomidotis irregularis ?

Hello all,
I was on a walk last Sunday in the Bronx, NYC where a friend of mine found a very interesting asco. It has a black fertile surface. The outer surface is scurfy and dark brown. It is rather thin and papery, especially after drying. It was growing on deciduous wood. Asci that I measured were 70-73 x 6.5-7.5µm. Spores are hyaline, biguttulate, ellipsoid and 7-10.5 x 3-4µm. Paraphyses are lanceolate, septate, they enlarge to about 4µm at the widest point. Many of the heads of the paraphyses became detached. I applied KOH and noticed that there was an exudate of dark red pigment. It also appears to be bitunicate. (Unfortunately I am having problems with my image capture equipment, so I don't have the best documentation of all of these features). Is this Ionomidotis irregularis?
Many thanks in advance for your help.
Ethan
