A gall is an abnormal growth produced by the host organism in response to the presence of another living organism . If the host is a plant, we call it a plant gall. The galls can be caused by animals (zoocecidia) and also by plants (phytocecidia) or fungi. The most familiair galls are caused by midges, wasps, mites and fungi, but gall-inducing organisms can be found in many more groups of organisms. This website will show you some of them.
