Branch dieback was observed on Phoenicean juniper trees, in a natural growing area on Caprera Island (Italy), during 2009 and 2010. Fungal isolates obtained from symptomatic twigs and branches showing dieback and bark necrosis were identified as Diplodia africana by analysis of morphological features and genomic DNA sequences of the ITS region and translation elongation factor 1-alpha gene. Pathogenicity was verified by stem inoculation of 3-year-old saplings of Phoenicean juniper. This is the first report of D. africana in the northern hemisphere, and of this fungus as a pathogen of Phoenicean juniper.
