Phyllactinia holodisci is a species of powdery mildew in the family Erysiphaceae. It is found in North America, where it affects the genus Holodiscus .
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 . [1] Another species of powdery mildew also infects this genus: Podosphaera holodisci , which forms a spreading, greyish-white coating on leaf uppersides.
The fungus was formally described in 2012 by Uwe Braun. [1]
