Hab. On the leaves of Cercis chinensis Bge. Prov. Mino : 

 Gifu (K. Hara I Oct. 8. 1908). 



Small dark brown spots first make their appearance on the 

 surface of the leaves. These spots frequently increase in size 

 so much that several originalh^ distinct ones blend together 

 and form large irregular patches. The color of the diseased 

 area changes from dark brown to grayish brown and a number 

 of perithecia appear as minute black dots in these regions.

Perithecia immersed, globose or hemisphaerical, subepidermal, 

 somewhat elevated, membranaceus, dark brown, 120-150 ft 

 high, 130-170 // (rarely 200 //) broad ; asci clavate or cylindri- 

 cal, 8-spored, 75-90 ft long 8-11 // broad ; spores arranged in 

 1 or 2-rows, fusiform or elliptical, 5-septate, constricted at the

Hab. On the diseased branches of Cinnamonum Camphora 

 Nees. Prov. Musashi : Komaba near Tokyo (K. Hara! Jun., 8,

On the young branches of C amphora-tree we first find small 

 roundish dark brown spots. These spots increase in size, and 

 frequently unite with each other to form large irregular patches 

 which change in color from brown to gray and sink slighth^ from 

 the general surface, developing a number of perithecia scattered 

 over the discolored area.
