Summary In central Italy, Pseudomonas syringae pv. syringae was isolated from Alnus glutinosa that showed, in spring, leaf necrosis and also sucker and twig dieback. The trees were located near a lake and a stream. Biochemical tests were consistent with those characterizing the pathovar. Pathogenicity tests yielded necrotic lesions on A. glutinosa and Syringa vulgaris leaves and also on lemon and orange fruits. In addition, whole‐cell protein profiles of the isolates and P. s. pv. syringae reference strains were identical. Some isolates showed positive ice‐nucleation activity. This is the first record of this pathogen on black alder.
