Cystothecananyuensis is a species of powdery mildew in the family Erysiphaceae. It is found in Asia on plants in the genus Quercus .
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. Cystothecananyuensis, like most Erysiphaceae, is highly host-specific and only infects species in the genus Quercus . It is currently only known from the type collection, on Quercus hypargyrea . [1]
The fungus was formally described in 1998 by J.L. Zhou as a variety of C. wrightii with the basionym C. wrightii var. nanyuensis. The variety was elevated to species by Uwe Braun in 2012. [2] The type specimen was collected in China.
