Abstract

In summer 2014 a shoot blight of mature trees of Cedrus atlantica was observed at several sites in private gardens and in public green spaces in the vicinity of Oldenburg, Lower Saxony. The disease is characterised by light brown discoloration of needles and fascicles, followed by dieback of the affected shoots. Based on specific morphological features as well as DNA sequence comparisons the pathogen was determined as Sirococcus tsugae. So far, this coelomycete had only been known from North America. The phytosanitary aspects resulting from the occurrence of a new tree pathogen in Germany are discussed.
