place when a bit of the iinceliuin ami chlaiiiNHlospores was used as the inoculum. 

 Unfortunately we have not been able to make infection experiments with the coni- 

 tiiosporesj as they are very rarely produced in the artificial cultures we have used. 



9. Summary 



(1). A serious leaf-siiot disease of Liipinus polyphylius is [jrevalent almost 

 every year in the vicinity of Sapi)oro and probably also in other districts, where 

 this plant is cultivated. 



(2). This disease is caused by Cenitophonini setosuni Kirchner, which has 

 been known up to the present time only as the parasite of certain species of Cytisns. 



(3), According to the description and figures, Pestalo:;3ia Lupiiii Sorauer 

 described b)' Wagnek and .Sokaui:k as the parasite of Liipinus Critikshanksii, I., 

 nintabilis and others does not belong to the Melanconiaccac, but is identical to 

 Ceiatophoriim sefosiim and should be treated as its synonym. 



(4). By a careful search we 1ki\ c collected the same fungus severely ; Ffic^in^f 

 the leaves of Cytisns capitatiis antl one other species of the same genus in the 

 Botanic Gartlen of our University. The identity of the fungi which attack the 

 two species of Cytisns and Ljipinus polyphylius was proved by cultural and inocula- 

 tion experiments. 



(5). Pure cultures of the causal fungus were isolated from the diseased areas 

 on the leaves of each of these three host-plants and its parasitism has been de- 

 monstrated b\' successful cross inoculations on the healthy plants. 



These investigations were carried out in the laboratory of plant pathology of 

 the tiokkaidö Imperial University. The writer wishes to express here his hear- 

 tiest thanks to Prof. Dr. Kixgo Mivabe for his kind suggestions and criticisms. 

 He wishes also to e.xpress his thanks to Mr. T. Fukushi and other gentlemen who 

 have kiiuUy helped him in various ways. *
