【 摘 要 】

Sonneratia apetalaFrancis Buchanan-Hamilton (Sonneratiaceae, Myrtales), is a woody species with high adaptability and seed production capacity. S. apetala is widely cultivated worldwide as the main species for mangrove construction. However, the study of diseases affecting S. apetala is limitted, with only a few fungal pathogens being recorded. Cryphonectriaceae (Diaporthales) species are the main pathogens of plants. They can cause canker diseases to several trees and thereby seriously threaten the health of the hosts. These pathogens includeCryphonectria parasitica(Cryphonectriaceae) causing chestnut blight onCastanea( Rigling and Prospero 2017 ) andCytospora chrysosperma(Cytosporaceae) causing polar and willow canker to  PopulusandSalix( Wang et al. 2015 ). Therefore, the timely detection of of Cryphonectriaceae canker pathogens onS. apetalais extremely important for protecting the mangrove forests.Two diaporthalean fungi, Celoporthe guangdongensis and Cytospora rhizophorae have been reported for the first time to cause canker on the branches of S. apetala. C. guangdongensis is significantly pathogenic and C. rhizophorae is saprophytic on S. apetala.
