Gallformers ID Notes

A large globular gall completely covered in long white wool, resembling a cotton ball. Apparently always found in pairs on either side of the midrib of a willow tentatively identified as Salix bebbiana. Where the wool is worn away, the gall is red-tan-brown. Integral, showing slightly on the top of the leaf but predominantly below the leaf. Observed in Yukon in June and July.
