Photos 6, 7, 10, 11 appear to show the ornamented chasmothecia/perithecia hyphal appendages:

Golovinomyces or Erysiphe?
Amended note (11/19):
Probably not downy mildew based on seemingly not being restricted to lower surface?

Research notes from:
https://pubmed.ncbi.nlm.nih.gov/30743683/
"White superficial conidia of the powdery mildew fungus occurred on adaxial and abaxial surfaces. However, the white powdery growth was more abundant on the adaxial surface. Leaf symptoms commonly appeared white from May to October. Along with the typical white powdery mildew, spot and/or necrotic symptoms with irregular violet-to-wine red surfaces were also frequently observed on overwintered leaves"
"Major genera including Cystotheca, Erysiphe, Microsphaera, and Phyllactinia have been reported to cause powdery mildews on Quercus plants. Until now, 22 Erysiphe species including E. abbreviata, E. alphitoides, E. calocladophora, E. gracilis, E. polygoni, and E. quercicola have been reported to cause powdery mildews on Quercus spp."

On Grindelia stricta, I believe.
The two leaves in photo 1 probably show two different stages of the same gall.

flammulatedDescripción
Galls along midribs of young Oregon Ash leaves. The gall part of each leaf feels hard and thickened to the touch, and folds upward to form a pocket. I opened a couple of them and found several small larvae inside the pockets (see photos).
This looks a lot like the galls described here:

Unfortunately, I neglected to take a nice photo series of the plant itself at the time that I took these shots, but I'm fairly certain it is the same species of elm which Chris documented in this observation:
