zitsermΠεριγραφή
This fungus infects Box elder (Acer negundo) and turns the twigs white, killing them. Sometimes the fungus looks like broken up black circles (see photo 1), a bit like cheetah spots, and sometimes it looks like complete circles. I have seen similar Box elder twigs with this fungus, where part of the pale twig was an orangish pink hue.
After letting the twig sit in a moisture chamber, pinkish goo started to ooze out of the black circles. I believe this is an anamorph of some Ascomycete. A photo of the conidia at 1000x is shown. The spores are elliptical / pill shaped and have numerous round guttules in them.

Growing on a curled Rhododendron catawbiense leaf. Ascocarps up to 0.7 mm wide; fringed with tufts of hairs; sessile. Ascocarps seated individually on small, white, membranous subicula. Not noticeably bioluminescent. Not noticeably fluorescent under UV light. Hair tufts composed of fascicles of smooth, hyaline hairs. Asci inoperculate and 8-spored with amyloid apical apparatuses. Spores hyaline, smooth and 3-septate. Spore measurements: (16) 17.1 – 20 (21.3) × (3) 3.2 – 3.8 (4.1) µm; Q = (4.4) 4.5 – 5.8 (6.2); N = 30; Me = 18.2 × 3.6 µm; Qe = 5.2

Fire pit. Microscopy. Ascospores approx. 15.0-17.0 x 7.9-8.8. Q=1.9. Multi-septate rounded ended hairs, some longer than 100µm; paraphyses greenish in iodine - many forked. (FBs were bright yellow-orange, which my camera has trouble picking up, so I had to pump up saturation to make them closer to their actual colour.) Vouchered. JET230703_02

ID help appreciated.
iNat was very consistent in its top suggestion: Stalked Hairy Fairy Cup (Lachnum virgineum).
Totally love that name. I didn't see stalks, but they were so tiny who would know?
I backed up a couple of taxon levels as a starting place.
