Cystotheca is a genus of plant pathogenic fungi in the family Erysiphaceae (powdery mildews). Members of the genus are found on Calophyllum, Castanea, Castanopsis, Murraya and Quercus species in Asia and North America.
== 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. The distribution of this genus is limited to Asia (from the Himalayas to Indonesia and Japan) and North America (western United States to southern Central America). Only Cystotheca lanestris and Cystotheca mexicana are not found in Asia.
