On chillies or peppers {Capsicum annuum and C. frutescens) three an- 

 thracnoses have been recorded to date. In 1889, Ellis described a very 

 destructive disease in America caused by Gloeosporium. piperatum E. 

 and E. Halstead^, in the following year, discovered another which was 

 considered to be different from the previous one, on account of the 

 presence of setae in the acervuli; it was consequently named Gollefo- 

 trichum nigrum E. and Hals. In 1913, Sydow^ described a new species 

 of Vermicularia on chillies, sent to him by Mr McRae from South India. 

 In India, especially in Bihar and Madras, Vermicularia Capsici Syd. is 

 the most destructive disease and causes a great deal of damage to the 

 fruits and to the plants as well, at least in Bihar. The other two diseases 

 have not as yet been reported to do much damage in India, but in Burma 

 they seem to cause much loss of the fruits. In 1917, an experimental plot 

 of two acres on the Pusa Farm bore a crop of chillies. The damage done 

 to the plants and fruits by F. Capsici was considerable but G. piperatum 

 was rarely found on fruits and C. nigrum was much more scarce. How- 

 ever, on the stem G. piperatum was slightly more prevalent than on the 

 fruits but it was invariably found only on the stem attacked by Chon- 

 nrpJiora Cucurbitarum (B. and Rav.) Thaxter and V. Capsici. As a rule 

 only mature fruits are attacked by G. piperatum and the other two
