Parauncinula uncinata

Parauncinula uncinata is a species of powdery mildew in the family Erysiphaceae. It is found on plants in the genus Quercus in Asia. It is known only from Japan.

Description

The fungus forms effuse, evanescent mycelium on the leaves of its host. Parauncinula uncinata, like most Erysiphaceae, is highly host-specific and infects only Quercus variablilis.

Taxonomy

The fungus was formally described in 2017 by Meeboon and Takamatsu. The specific epithet derives from the uncinate appendage tips.
