Gallformers ID Notes

A cream-colored, slightly hairy open cup with a ring of spurs below the rim, near the leaf edge on Quercus chrysolepis. Observed in California in September.

This is Joyce Gross' Gall type #7, and her observation is apparently the only report of this gall. She suggests it may be Weld's Figure 178, which refers to a very different gall on Quercus dumosa. This may be a typo and meant to refer to either Figure 177 or 176, but neither of these galls match the open top or ring of spurs shown in her photos.
