Podosphaera amelanchieris is a species of powdery mildew in the family Erysiphaceae. It is found across Europe and North America, where it affects the genus Amelanchier.
Description
The fungus forms a thin, light, weak coating on host leaves, rarely distorting growth from the underside. Podosphaera amelanchieris, like most Erysiphaceae, is highly host-specific and infects only the genus Amelanchier.[1] Another species of powdery mildew also infects this genus: Phyllactinia amelanchieris, which has weak, very thin, often smooth growth, on the undersides of leaves.[2]
Taxonomy
The fungus was formally described in 1927 by Maurizio. The specific epithet derives from the host genus.
