G. gallaediplopappi affects that tall and sturdy plant Diplopappus umbellatus Torrey & Gray.
...
G. gallaediplopappi forms its gall a foot or two feet above the ground, and the growth above it is unaffected.
...
I have opened dozens of the galls, and never found one lined with silk, nor one with the way of exit closed with a plug.
