works which treat of Sclerospora the characters of the ripe fruit 
are taken as the basis for classification, and on this basis it is 
impossible to separate the species from Scl. graminicola. 
On Setaria italica similarly, only oogonia and oospores have 
been observed in India. These are identical with the above in shape 
and colour, and are almost exactly thesame size. As Scl. gramini- 
cola is already widely known on this host, this merely adds a new 
locality for its ravages. Traverso (1902 (2) ) has found a special 
form. Scl. graminicola var. Setariz italicee—in Italy, differing from 
the type, in having larger oogonia and oospores ; but the fungus in 
India agrees in all respects with those on other Setariz in Sydow’s 
exsiccata and from the measurements given must be referred to 
the type species, not the variety. 
Finally thefungus on Kuchlena luxurians agrees in its asexual 
stage with Scl. graminicola and, as no other species is known to 
possess this stage, may be referred provisionally to it.
