Conidial fructifications are found on the under surface of the green 

 leaves. Couidiophores which grow solitary out of the stomata and are 

 of a short duration, agree exactly with those of the European species 

 in the mode of their branching as well as in their form, except some 

 minor differences in the form and size of their conidia (Figs. 20-22). 



According to Schroter, 1 * the conidia of the European species are 

 roundish-oval in form while those of our fungus vary from roundish- 

 oval to oblong. 



The following is the result of my measurement of the different 

 parts of our fungus, which are in general somewhat larger in size than 

 those of the European species.

Nees and Cladosporium herbarum Link. 

 are the two saprophytic fungi which occur almost constantly in company 

 with Sclerospora gramminicola (Fig. 23). As regards the germination of 

 the spores of Sclerospora gramminicola as well as the nature of other 

 parasitic fungi which cause other diseases of Setaria italica further 

 discussion will be given in a future report.
