Beech bark disease is a disease that causes mortality and defects in beech trees in the eastern United States, Canada and Europe. [1] [2] [3] In North America, the disease occurs after extensive bark invasion by Xylococculus betulae and the beech scale insect, Cryptococcus fagisuga. [4]
Maple bark disease, or maple bark stripper’s disease, is an uncommon condition caused by exposure to the spores of C. corticale. [5] The spores are hyper-allergenic and cause a hypersensitivity pneumonitis. [6] [7] The disease has been found among workers in the paper industry employed to debark, cut and chip maple logs.

Trees have natural chemicals that keep most fungi at bay, but climate change could be making trees more vulnerable, researcher says.
Where beech bark disease becomes established, most of the larger trees will die. Some trees seem to be partially resistant to the disease and a small number seem to be completely resistant. This may be partly due to the fact that trees with smooth bark provide fewer cracks and crevices in which the scale insect can flourish. [8] [9]
