A very small, gray-brown, stellate-hairy gall replacing new buds on new growth of Quercus fusiformis. These galls are found fresh in July but frequently persist on the tree into following years; older galls are easier to find than fresh ones. In July, some galls have been found containing a fully grown larva and thin walls, while others are still thick-walled and green inside. These galls were originally mistaken for the sexual generation galls of DIsholcaspis cinerosa, which appear and emerge much earlier in the growing season (late March-April), shortly after bud burst. D cinerosa galls also have much thinner walls and are much less firmly attached to the tree, and frequently remain surrounded by bud scales to some degree, while the present gall seems to always replace the full bud including scales.

Unpublished genetic sequence data from the Nicholls and Egan labs independently place male and female cynipini reared from these galls as the sexual generation of Callirhytis quercusbatatoides.
