Apple is an economically important fruit crop in northern Shaanxi Province in China. In recent years, a new type of apple black spot disease, “bagged apple black spot disease,” has occurred in the main apple production area of Yan’an City, Shaanxi Province, during the apple ripening season. It seriously affects the appearance quality and commercial value of apples. In this study, 120 isolates recovered from symptomatic apples were identified based on morphological characteristics, pathogenicity, and multilocus sequence analyses of the internal transcribed spacer of ribosomal DNA (rDNA-ITS), translation elongation factor 1-α (
