Cryptostroma corticale
Cryptostroma corticale
Creates dark coatings on the trunks. These are formed by the sexual stage of the fungus – the fruiting bodies that produce spores. Cryptostroma corticale is harmful to trunks and branches. It causes tree diseases especially after dry summer periods. The fungus attacks the wooden part of the trunk (xylem) and penetrates back to the surface of the trunk to the cambium and bark. Black plates form under the bark. The mushroom attacks the mountain maple, less linden and chestnut. The occurrence of the disease usually leads to the death of the trees quite quickly.
Black plates form under the bark.
