Eriophyes coryli n. s.

Host: Corylus americana

A deformity of the leaf brought about by the excessive shortening and thickening of midrib and some of the main veins, producing puckering of the blade tissues. The thickened sac-like veins are really the galls, opening by slits above. Pubescent. On leaves of hazelnut, Corylus americana. One specimen. September.
