Large, hairless, yellow-green, irregularly globular galls largely on the lower side of leaves of Salix bebbiana. These galls resemble Euura salicispomum on Salix eriocephala, and like that species, a wide portion of the gall is visible from the upper side of the leaf but it does not project substantially higher than the leaf. The surface below is smooth but speckled with white or red-brown lenticels, which are absent from the upper side. Observed in Minnesota in June.
