Gallformers ID Notes
“
Light-green hairless pocket swellings along the lower side of lateral veins of Alnus rubra, opening with a slit above. Observed in California in October. This gall differs from Russo's leaf-fold gall in occurring in the fall rather than the spring and on the side veins rather than the midrib. They may prove to be closely related or the same species.
