The characters given above agree particularly closely in the 
case of the cow-pea fungus of Smith and the indigo fungus. In the 
other cases some divergencies occur, but the general behaviour 
corresponds fairly well. The differences, such as they are, are as 
general between the three Indian strains as between these and the 
American, and are such as are inseparable with working with 
media of the indefinite composition of those mentioned. 
Noone could think of separating as distinct species, fungi 
agreeing so generally in their microscopic characters and cultural 
behaviour as the Neocosmosporas studied in the United States 
and in India,
