Gallformers ID Notes

This gall is often identified as Callirhytis furva, but is distinct from it in having long hairs only arranged in a flat fringe around a scar at its apex, not uniformly obscuring its surface. It is found on similar hosts (various red-group oaks including at least Q phellos, velutina, ilicifolia, rubra, and palustris but likely many others) and in a similar arrangement (scattered in small clusters along the upper leaf veins). It also closely resembles this undescribed gall, which differs only in that it lacks any long hairs. Galls have been observed that seem intermediate (2) between the two undescribed galls.

Observations are collected in this page on Bugguide and in Callirhytis furva on iNaturalist.

Quercus ellipsoidalis added tentatively as a host based on this unconfirmed observation.
