great importance is laid on mere measurement. But I can not 

 overlook the fact, that these morphological characters are 

 apparently constant in the natural state. 



P'inally, species of Gloeosporium seem, to have a genetic 

 relation with the following three genera of Ascomycetes; Glome- 

 rella (5.9), Gnomonia (7) and Pseudopeziza (8). To which of 

 these genera our fungus is related has not yet been proved up 

 to this time. 



From the foregoing statements made on the distinctness of 

 our fungus from its related species, I may be justified in con- 

 sidering it as a new species. Its diagnosis is as follows :— 



Gloeosporium Kaki n. sp. 



Spots, on fruit, scattered, prominent, slightly sunken, at 

 first very small, at last 1—2.5 cm. in diam., roundish or elliptical 

 in shape, sometimes confluent forming irregular specks, blackish 

 in colour, with yellowish brown margin. 



Conidiophores, erect, simple, hyaline, 10-25 x 3—5 fi. Conidia 

 coze out in salmon-coloured, sticky mass, cylindrical or long 

 ellipsoidal, rounded at both ends, straight or rarely^ slightly 

 curved, 1 celled or rarely 2 celled, hyaline, 18-25 (rarely 32 fi) 

 X 4-6 //. 



In germination, a septum is seldom formed at middle, germ- 

 tubes produced at both ends. Appressoria readily produced 

 both in water and nutrient media, roundish or polygonal, wall 

 smooth, thick and black, 7-9 x 6-8 fi.
