Background
Sonneratia apetala Francis 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 include Cryphonectria parasitica (Cryphonectriaceae) causing chestnut blight on Castanea (Rigling and Prospero 2017) and Cytospora chrysosperma (Cytosporaceae) causing polar and willow canker to Populus and Salix (Wang et al. 2015) . Therefore, the timely detection of of Cryphonectriaceae canker pathogens on S. apetala is extremely important for protecting the mangrove forests. New information
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.
