Carpinus betulus, Nieuwendam

parasite

The fungus causes extensive lesions in the bark of thick branches; in the course of several years they may become surrounded by voluminous ridges of wound tissue. Out of the wound erupt conspicuous groups of cinnabar red globular perithecia; in whitish masses also conidia are formed. The infection mostly start at a mechanical damage, like by pruning.
