Andricus solitarius f. agamic
The agamic galls are in oak buds; elongate and slightly curved, and covered in red/golden hairs when young; later the hairs drop off leaving a smooth gall.
[Note: the inconspicuous sexual galls are formed on oak catkins]
Other species of Andricus cause small galls to form in buds
Photograph the gall on oak, and note the host species
