The females of the cynipidae Plagiotrochus quercusilicis cause red galls on green oaks (Quercus ilex) and kermes (Quercus coccifera). These galls appear in both, leaves and masculine inflorescences or tassels. The gall shape is like a ball when it is in leaves. However, gall shape in tassels is like a rod, therefore is named variety fusifex. The 1st picture shows the galls in leaves of green oak, while the 2nd and 3rd pictures show it in the kermes. The next pictures display galls of the variety fusifex, the 4th and 5th in the tassels of green oak and the 6th and 7th in that of kermes.
