Gallformers ID Notes
“
Long, thin, linear galls along the lower sides of Quercus alba leaves, green when fresh but turning black from the center out. A shallow pinched pocket of the lamina typically found between veins but sometimes along a vein, integral to the leaf, opening along a line above. The galls somewhat resemble Weld's unidentified gall similar to Phylloteras sigma but straight (also found on Quercus alba) but differ in being integral, not always along veins, and of varying length.
Observed in late May in Pennsylvania and Maryland, and in June in New York.
A similar gall has been observed on Quercus stellata, sometimes with shorter and thicker pockets.
