Erysiphe vaccinii var. elevata

Niagara Parks Botanical Gardens, Niagara Reg., Ontario

Host: Catalpa bignonioides (cultivated)
Tentative ID based on host association. This seems to be a very infectious mildew on Catalpa, although Liu and Braun (2022) note several other Erysiphaceae genera occurring on the genus.
