Hemmi : A New Brown-Spot Disease of the Leaf of Glycine hispida Maxim. j ;- 



ters of these two fungi are as follows: — 



Septoria sojina Tlnim. Septoria sp. 



I. Pycnidia epiphyllous amphigenous 



conico-globose globose to conico-globose 

 44-100 n 



2. Conidia cylindrical to subcuneal filiform 



I septate c-3 septate 



12-18 X 4,5-5,0// 21,0-52,5 X 1,4-2,1 /i 



3. Spots irregular in shape mostly angular 



bordered unbordered 



Other species of Septoria which are parasitic on the leaves of leguminous 

 plants, differ from the present fungus also in the macroscopical or microscopical 

 appearances. From the foregoing statements, I consider the present fungus to be 

 a new species, and the following diagnosis is given. 



Septoria Glycines Hemmi, sp. n. 



Spots amphigenous, at first angular, brown to reddish brown, unbordered, at 

 last dark brown or blackish brown, having greyish center, scattered or gregarious, 

 often confluent, commonly 2-3 mm. in diameter; pycnidia amphigenous, mostly 

 epiphyllous, scattered, globose or conico-globose, membranaceous, brown or dark 

 brown, 44-100 ij. in diameter, at first covered by epidermiis, then erumpent; spores 

 hyaline, filiform, more or less curved, or sometimes straight, smooth, guttulate, 

 obscurely septated, 1-4 celled, 21.0-52.5 /i long, i. 4-2.1 //broad.
