Silver date palm ( Roxb.) is an important ornamental plant in southern China. In October 2021, a serious anthracnose-like leaf spot of silver date palm was observed at a park in Haikou City, China. Some brown spots with yellow halos around the lesions appeared on the middle and lower leaves of the tree crown. The disease incidence reached 100% of trees and 32.8% of leaves. The pathogen was identified as by morphological characters, pathogenicity tests and multi-locus phylogenetic analyses combined with ITS, , , and ApMat sequences. This is the first report of causing the leaf spot of silver date palm in China.
