Several-many small tufts of white wool emerging from veins on the lower side of leaves of Quercus alba. These galls clearly resemble Neuroterus quercusverrucarum, but are suspected to be a distinct species (or possibly a distinct generation of the same species) because they have been observed much earlier in the growing season than that species has been reported on other white-group oaks, and they appear on first-flush leaves rather than secondary growth, as N quercusverrucarum typically does. Observed in Georgia and Virginia in April and May (whereas N quercusverrucarum is understood to first appear in July).
