Tubeuf phot.) injurious and widely distributed disease of various species of Prunus, especially plum and cherry. The living branches and twigs become coated with a crust of warty excrescences, and at the same time are more or less thickened and deformed. A mycelium permeates the tissues of those swollen twigs, and forms black crusty stromata in which the perithecia are embedded. The perithecia contain simple paraphyses and eight- spored asci. The spores consist of a larger and a much smaller cell. (Pycno-conidia are produced frequently in artificial culture, 'Farlow, Bvlletin Bussey Institution, Part v., 1876.
