slightly tufted, while in others it is untufted. The perithecia are flask- 

 shaped, caespitose, membraneous and dark brown in colour. They 

 measure 315-7-385 x 123-2-292-G/i. 



The asci (Figs. 10, 11 and 12) are sessile and clavate and measure 

 GO-0-93-5 X 88-12- 1;m. 



The ascospores (Fig. 13) are hyaline, slightly curved, subdistichous 

 and elliptical. They measure 13-2-20-9 x 4:-4-6-6/x. In old perithecia the 

 ascus wall has been found to be disintegrated, setting free the ascospores. 

 In these old yjerithecia the ascospores are found to be empty of their 

 protoplasmic contents and to have become septate, generally once and 

 rarely twice, and their walls have turned distinctly pale brown in colour, 

 as in the case of the chilli Glomerella. 



The perfect stage of the Carica anthracnose is identical with the 

 chilli Glomerella in both morphological and cultural characteristics. 



Summary. 



Gloeosporium piperatum E. and E. and Colletotrichum. nigrum E. and 

 Hals, are not known to be destructive to chillies in India but they cause 

 much loss of fruit in Burma. 



These fungi are considered to be identical and to be the conidial forms 

 of Glomerella cingulata (Stoneman) Spauld. and v. Sch., which is shown 

 to be synonymous with Gnomoniopsis {Glomerella) piperata Stoneman, 

 the ascogenous stage of G. piperatum E. and E., according to Miss Stone- 

 man. 



The perithecia-producing faculty does not depend on the nutrient 

 medium on which the fungus is grown but depends on the race or strain. 



This faculty is not a fixed hereditary character but is lost by culti- 

 vating successive generations on the same medium at room temperature. 



There is a great deal of variation in the size and hairiness of the neck 

 of the perithecium and in the size and shape of asci, and therefore 

 cultural characteristics cannot be much relied upon for determining the 

 species. 



The perithecia are aparaphysate. 



The ascospores are hyaline, unicellular and slightly curved, but in 

 old perithecia they are found to be septate and their walls coloured 

 brown. 



In cultures the presence of setae is not a constant character. 



In cultures of the perithecial strain there are very often sudden 

 variations in the characters of the growth of the fungus.
