Over the growing seasons of 2011–2013, various pistachio (Pistacia vera L.) cv. Fandoghi, and wild pistachio (P. atlantica Desf. subsp. mutica) trees were inspected in Iran to determine the aetiology of trunk diseases with specific reference to species of Phaeoacremonium and Botryosphaeriaceae spp. Samples were collected from branches of trees exhibiting yellowing, defoliation, canker and dieback, as well as wood discoloration in cross sections. Fungal trunk pathogens were identified using morphological and cultural characteristics as well as comparisons of DNA sequence data of the ITS and TEF-1α (for Botryosphaeriaceae species) and β-tubulin gene (for Phaeoacremonium species) regions. Phaeoacremonium parasiticum was the dominant species followed by Phaeoacremonium aleophilum, Botryosphaeria dothidea, Neofusicoccum parvum, Phaeoacremonium cinereum, Phaeoacremonium viticola and Dothiorella viticola. Pathogenicity tests were undertaken to determine the role of these species on pistachio under field conditions. Neofusicoccum parvum and Pm. aleophilum caused the longest and smallest lesions respectively. This study represents the first report on the occurrence and pathogenicity of Phaeoacremonium species on P. vera cv. Fandoghi. This also represents the first report of Pleurostomophora sp. on pistachio and Pm. parasiticum and D. viticola on wild pistachio.
