Massaria Disease has been seen in mature trees from roughly 40 years of age and above

About Massaria Disease:
Plane trees in Britain are suffering from Massaria disease. This disease can cause large lesions on the upper surfaces of major branches and can cause the branch to drop. In 2009 tree management teams in London started to notice large lesions and branch drop on the branches of plane trees. However it is not yet clear whether a fungus is the primary cause of the disease, researchers are still having a look into the disease to try and find the main cause. The result of this is that the main cause is still unknown and will take a lot of work.
