Gallformers ID Notes

A cluster of small kernels emerging from a major side vein of Quercus rubra toward the lower side of the leaf. Loosely covered in long hairs, of varying colors from green-yellow to dark purple, widening from the base to a flat end with a significant dimple at the apex. Observed in Illinois in October.

This gall bears some resemblance to the gall known as Neuroterus laurifoliae, sharing the same distinctive conical, dimpled structure to their clustered cells. The gall differs in its host plant (N laurifoliae is known from Quercus imbricaria, laurifolia, and possibly hemisphaerica) and its relatively sparse wool.
