 effecl on the plant is more or less different according to the differencj of its hosts. The ty/M«5-leaves af- 

 fected with the fungus generally fall down very quickly ; but the affected leavei of Lupinus polyphyllus dry 

 up gradually in summer and remain attached for a long time. Therefore, the brownish shriveled leaves are 

 readily seen even at a distance. 



Symtoms of Cf/tisuH sp. The Cytisus plant.s affected by the disease and 

 studied by us were all of grown plants. In the case of Cytisus sp., whose name is 

 not identified, the fungus produces characteristic spots on its leaves. The diseased 

 areas show first as dark brown very minute spots. These rapidly enlarge, and 

 soon form brown or blackish brown spots 4 to 8 mm. ia diameter. The spots 

 appear on the both sides of the leaves, but on the upper surface they are some- 

 what deeper in color. These spots are mostly circular or semi-circular or some- 

 times irregular in shape. The margin of the spot is not especially bordered with 

 a deeper color, but on the larger spot the concentric dark-colored rings are form- 

 ed generally. The diseased leaves fall down immediately. Tlie symptoms in the 

 case of the grown plant of Cytisus capitatus are, on the whole, similar to those of 

 the above -described Cytisus sp. But it seems to me tliat the spots are generally 

 smaller in this case and rather irregular in shape. The .semi-circular spots ex- 

 tended from the ti[) of the leaves are often found. 



Symptoms of LnpinuH poli^plii^llnH, WAGXEii and Sor.vuer('3) des- 

 cribed the symjitoms of the disease of Lupiiius Crui/cshanksii, L. iimtabilis and 

 others caused by the present fungus. They reported that the fundus attacks the 

 cotyledons as well as the leaflets of these plants. In the vicinity of Sapporo, we 

 have always noticed the disease affecting the leaves and rarely petioles, but we 

 have not yet had an opportunity to find the cotyledons attacked. The fungus 

 produces a characteristic spot on the leaflets of the affected plant. The diseased 

 areas show first as small, brown or dark brown .spots on the both sides of the leaves. 

 They are irregular in s]ia[)e in the early stage. Hut they rapidly enlarge, produc- 

 ing ;it last various sized brown spots, which are mostly circular or semi-circular 

 in shape and 5-10 mm, in diameter, not seldom exceeding 14 mm. The margin 

 of the spot is not especially bordered with a deeper color. The spots become 

 confluent often forming large irregular brown or darlv brown patches on the sur- 

 face of the leaves. They extend also often from the margin to the center of the
