circular
Discrete lesions are small (only 2-4 mm diam.), circular, and dotted with only 2-7 conidiomata, which are easily seen with naked eye. Under a dissecting microscope or with a simple lens, the ostioles surrounded with darker cells are clearly seen just like a ring. These characters would be helpful for diagnosis of this species. 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'.
