They were identified by means of morphological characters and multigenic analyses of a partial sequences of the actin gene, and a part of the ?-tubulin gene. Combining morphological, culture and molecular data, three Phaeoacremonium species, such as Pm. aleophilum, Pm. alvesii and Pm. parasiticum, already known as responsible of severe decline of olive in Apulia, were isolated together other three Phaeoacremonium species, such as Pm. italicum, Pm. sicilianum, and Pm. scolyti, associated for first time with wilt, decline and dieback of olive orchards in Italy and in worldwide. All six fungi were early isolated from vineyards, manly, and from other wood hosts, secondary. In order to understand and to confirm their involving in wilt and decline olive trees, the pathogenecity assays were performed on shoots from young olive plants. The results indicate that all six Phaeoacremonium species are able to cause discoloration, necrotic wood and death of shoots, although, a variable aggressiveness was observed, as Pm. italicum, Pm. aleophilum and Pm. sicilianum produced biggest necrotic lesions than others Phaeoacremonium species assayed.} }
