Gallformers ID Notes

A large, globular, hairless or nearly-hairless, detachable, pink gall on a leaf of Quercus john-tuckeri. The gall occupies enough of the distal end of the leaf that it is not clear whether it attaches to the midrib, side vein, or lamina. The gall came to a puckered apex with loose pieces of tissue reminiscent of sepals on a fruit. Observed in California in September.

According to Joyce Gross, this is an inquiline-modified gall, likely induced by Cynips douglasii or possibly an undescribed relative.

Cf Russo's pink-cone gall on Quercus cornelius-mulleri.
