From the article Phyllactinia holodisci on Wikipedia (CC BY-SA), quoted section by section
Description
The fungus forms weak, very thin, often smooth growth, on the undersides of host leaves. P. holodisci, like most Erysiphaceae, is highly host-specific and infects only the genus Holodiscus. Another species of powdery mildew also infects this genus: Podosphaera holodisci, which forms a spreading, greyish-white coating on leaf uppersides.
