Cecidology - the study of Galls
Cecidology is the name for the study of the world of galls.
A gall or a cecidium (plural: cecidia) is an abnormal growth in a plant caused by specific gall-causing insects, mites, or fungi.
Examples include the Oak Apple, that looks like a small round fruit but is actually a plant deformity caused by a wasp.
