what is it?

Cola-nut galls develop as a chemically induced distortion of leaf axillary or terminal buds on pedunculate oak ( Quercus robur ) or sessile oak ( Quercus petraea ) trees, caused by the agamic gall wasp Andricus lignicola (Hartig, 1840) which lays single eggs within leaf buds using their ovipositor. A previous name or synonym for the species A. lignicola is A. lignicolus and A. venheurni .
