1. In 1922, an epidemic cercosporellose of the cultivated lily(Lilium Maximowjczii) occurred in some districts of Hokkaido. The diseasse is chiefly confined to the foliagei of the lily plant. 2. The morphological characteristics of the causal fungus coincide pretty well with those of Cercosporella inconspicua(Wint.) von Hohnel. But, it seems to me that correct judgement should be passed by further investigations. 3. The symptoms of the disease may be divided into three distinct stages. In the primary stage, the affected areas show a powdery milew-like appearance; in the tertiary stage or lesions are characterized by brownish colour, and in the tertiary stage or the final stage, a blackened and burned appearancc is characteristic. 4. According to the writer's experiments, the causal fungus hybernates in the dead tissues of the leaves.
