higher resolution images available at inaturalist.org/observations/179449419.
Trochila initially suspected, but microsocpy seems to contradict this.
Attempts at rehydration to open potentially hygroscopic apothecia was unsuccessful.
Stage micrometer was recently lost, and so sadly I have no measurements at this time.

Re : indet. Rhytismatales on oak leaf - North Carolina, USA
Hi Danny, it is Rhytismatales - perhaps a Coccomyces or Hypoderma. Not sure if it isn't immature - I don't see spores floating around and the ones in the asci seem immature. You could try putting it in a moist chamber for 3-7 days and see if they open up.
