In recent years, leaf necrosis and twig dieback in the olive crop have beendetected in Sicily (Italy). In this article, we identify the predominantfungal species associated with symptomatic leaves and twigs, usingmorphological features and DNA sequencing of the internal transcribedspacer (ITS) region, as Alternaria alternata, Arthrinium phaeospermum,Phoma cladoniicola and Ulocladium consortiale. The pathogenicity of thesefour species was tested on olive plants cv. Biancolilla. All species werepathogenic on leaves, but only U. consortiale produced cortical lesions ontwigs, thus suggesting its main role in the Olea europaea twig dieback. Toour knowledge, this is the first report of A. phaeospermum, P. cladoniicolaand U. consortiale as olive pathogens.
