 effect on the plant is more or less different according to the difference of its hosts. The C>''"'«-leaves af- 

 fected with the fungus geierally fall down very quickly ; Imt the affected leaves of Litpinus potyphyUtis dry 

 up gradually iu summer and remain allached for a long time. Tlierefore, the brownish shriveled leaves are 

 readily seen even at a distance. 



Symtoms oiCt/Usiis sj). The Cytisus plants affcctcil by the disease and 

 studied by iis 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. in diameter. The s])ots 

 appear on the both sides of the leaves, but on the upi)er surface they are some- 

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

 times irregular in shape. Tlie 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. The symptonis in the 

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

 the above^dcscribed Cytisus sp. But it .seems to mc that the spots are generally 

 smaller in this case and rather irregular in sha[)e. The semi-circular spots ex- 

 tendctl from the tip of the leaves are often found. 



Symptoms of Luphms pollßpliißlhts. Wagnkk and Sok.\uuk('3) des- 

 cribed the symjjtoms of the disease of Lnpiiius Cruikshaiiksii, L. muiabilis and 

 others caused by the present fungus. They reported that the funj^is attacks the 

 cotyledons as well as the leaflets of these plants. In the vicinit>' of Sapporo, we 

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

 have not yet had an opportunit)- 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 shape in the early stage. Hut they i^apidly enlarge, produc- 

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

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

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

 confluent o.ten forming large irregular brown or dark brown patches on the sur- 

 face of the leaves. They e.Ktend also often from tlie margin to the centei' of the
