Recently, outbreaks of anthracnose disease in A. compressus have been observed in Hainan and Guangdong provinces in southern China. During late winter and early spring, in some badly infected lawns, the incidence of anthracnose on carpetgrass approached 100%. Under high-moisture conditions, the crowns and oldest leaf sheaths of affected carpetgrass become necrotic, which led to whole lawns turning reddish brown. We first confirmed pathogenicity by inoculating a conidial suspension of the fungal species onto uninfected A. compressus. Next, we performed a phylogenetic analysis based on the combined ITS, Sod2, Apn2, and Apn2/Mat1 regions and confirmed the pathogen to be a novel species in the falcate-spored graminicolous group of the genus Colletotrichum. Microscopic examination showed that the species was also morphologically distinct from other similar species of Colletotrichum. As a result of the molecular, phylogenetic, morphological, and pathogenicity analyses, we proposed the name Colletotrichum hainanense sp. nov for this undescribed fungal pathogen in this study.} }
