Soot Bark Disease
The Rußrindenkrankheit is a fungal disease of maples .
The disease is caused by an infection with spores of the fungus Cryptostroma corticale . Diseased trees can be recognized by wilting , loss of leaves , signs of death of the crown and cambium necrosis , elongated bark and mucus flow on the trunk. Infested logs can show green and blue discoloration when cut. Infections are favored by dry and hot climates and water scarcity. The process of death can take several years. Older trees with good water supplies are less prone to infection. The disease was first observed in Germany in 2006.
When inhaled, the fungal spores can cause severe inflammation of the alveoli, accompanied by a dry cough, fever, shortness of breath and chills.
