The Septoria leaf spot on Patrinia spp. seems to be not common in Korea. The lesions were usually formed on the leaves faced to the soil. Occasionally the leaves attached on the stem were found to be infected during rainy season. Since the lesions are generally small, circular and scattered on the leaves, the Korean name of the disease is suggested as 'Jeom-muni-byong', which means literally 'small and scattered-lesion-disease'.
