摘要：
Elaeagnus pungens is an ornamental plant used in landscapes and is native to China and Japan. In Nov. 2015, a leaf spot was found on El. pungens in the Sheshan National Forest Park located at Shanghai. A fungus was isolated from the margins of the lesions and one isolate, EP8, selected for identification and pathogenicity tests. Morphological characteristics of the fungus were similar to Epicoccum latusicollum. Phylogenetic analysis using concatenated sequences of ITS, LSU, TUB, and RPB2 also showed that isolate EP8 clustered with strains of E. latusicollum, a relationship supported with a high bootstrap value. This report is the first of E. latusicollum causing leaf spot on El. pungens.
