Small globular integral swellings in numbers in the lamina of Vitis leaves. The galls are distinguished from Vitisiella brevicauda by their smaller size, greater numbers, and lack of agglomeration, and especially by the presence of a distinct tuft of white to red hairs emerging from the upper or lower side of the gall. On the opposite side, the galls are hairless and glossy, a lighter green than the unaffected lamina shading to yellow, orange, and red.

Dr Gagne has identified larvae from this gall as Vitisiella, as reported in this paper by Buhl and Eiseman
