Cercospora apii is a fungal plant pathogen, who causes leaf spot on celery, and found on other plants, including Impatiens.Yang, Lijuan, et al. "Complete genome sequence resource for Cercospora apii causing leaf spot of celery." Molecular Plant-Microbe Interactions 36.10 (2023): 670-673. Since the genus Cercospora is one of the largest and most heterogeneous genera of hyphomycetes, numerous species described from diverse hosts and locations are morphologically indistinguishable from C. apii and subsequently are referred to as C. apii sensu lato.Groenewald, Marizeth, Johannes Z. Groenewald, and Pedro W. Crous. "Distinct species exist within the Cercospora apii morphotype." Phytopathology 95.8 (2005): 951-959.
