First report of Biscogniauxia mediterranea causing canker on wild almond (Amygdalus scoparia)

摘要

Biscogniauxia mediterranea causes charcoal disease on Quercus castanifolia, Q. brantii and Zelcova carpinifolia in Iran. This report introduces wild almond (Amygdalus scoparia) as a new host species for B. mediterranea in Iran. In 2015, symptoms of dieback of A. scoparia trees were observed for the first time in the Lorestan Forests of Iran. The causal fungus B. mediterranea was recovered from cankered tissues and identified based on morphology, and sequence analysis. Pathogenicity tests on two-year-old A. scoparia plants showed that B. mediterranea could cause lesions.
