Cystotheca vignae


Cystotheca vignae is a species of powdery mildew in the family Erysiphaceae. It is found in Asia on plants in the genus Vigna.

Description

Many Cystotheca species form dense, white or brown, distorting patches on the leaves of their hosts. Some species in this genus are also known to cause witch's-broom galls on their hosts. Cystotheca ''vignae, like most Erysiphaceae, is highly host-specific and is only known to infect Vigna. Other species of powdery mildew are also found on the same genus, such as Erysiphe vignae''.
