GALL.—Minute, elongate-oval, hard but thin-walled cells, usually with a slightly elevated apex in center of top surface ; surfaces of galls minutely granular, each cell attached by a broad area to the under surface of the leaf, not buried in the sort of depression
characteristic of American species of the group, and showing no deformation unless a slight discoloration on upper surface of leaf ; cells densely covered and entirely hidden by a circular tangle of long, whitish trichomes which contrast sharply with the normally hairy under surface of leaf ; cells averaging 0.7 mm. in length and less in diameter, the whole mass of hairs on each gall averaging 2.5 mm. in diameter. Galls densely covering under surfaces of leaves.
HOST.—Quercus macrophylla, the larger-leaved white oak of the area.
