| Note： |
This fungus differs from other Pseudocercospora or Cercospora-like fungi in the host family Ranunculaceae by its subhyaline, curved conidia which are narrowly obdavate to almost filiform. Cercospora filiformis Davis (Wise. Acad. Trans. 18:266, 1915) on Anemone patens L. also has its conidia filiform in shape but it differs from this fungus by its well developed stromata (40-125 μm wide). | |||
