Phyllactinia holodisci is a species of powdery mildew in the family Erysiphaceae. It is found in North America, where it affects the genus Holodiscus.

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.[1] Another species of powdery mildew also infects this genus: Podosphaera holodisci, which forms a spreading, greyish-white coating on leaf uppersides.

Taxonomy

The fungus was formally described in 2012 by Uwe Braun.[1]
