hyph^, and, as Stevens and Hall (9) have already pointed out, 

 afford ground for reflection when we consider the characteristics 

 on which some groups of the Fungi imperfecti are classified. 



Against a parasite such as Scl. Oryzce it is difficult to see 

 what remedial measures can be employed with success. The 

 sclerotia of the fungus undoubtedly perennate in the soil, where, 

 under favourable conditions, they germinate and produce a 

 mycelium which attacks the paddy crop. Cattaneo suggests 

 the application of salammoniac, with a view to killing the 

 sclerotia in the soil. Even if this is successful on a small scale, it 

 is manifestly impossible to the extent which would be necessary 

 in India. Probably the breeding of resistant varieties is the 

 only method by which any permanent resistance could be made 

 in the case of a field crop such as rice. Fortunately the damage 

 done in India at present does not appear to be sufficient to bring 

 this question within practical consideration.
