A contribution to the infection biology of dieback of Pinus nigra caused by Scleroderris lagerbergii Gr. In the buds the dead cells of the blade margins of the scales are first invaded. In December the fungus grows into the living parenchyma cells of the scales (cataphylls). In the long shoots hyphae could be observed in the cells of the epidermis and hypodermis in August, and in January of the year following infection the living tissue of the primary cortex (cortex parenchyma) is invaded at and between the needle bases.
