Description

The fungus forms thin, white irregular patches on the leaves of its host. Erysiphe convolvuli, like most Erysiphaceae, is highly host-specific and infects only plants from a few genera, namely Convolvulus and Calystegia. There is also a record from Ipomoea, which was reported as Erysiphe convolvuli but may be an unknown but closely-related species.

Taxonomy

The fungus was formally described in 1805 by De Candolle. The type specimen was collected by himself in France.
