In ceitain parts of North America, especially in the northwest 
United States and the adjacent parts of Canada, this fungus, 
together with T. Tritici , does considerable damage to wheat." It 
can be prevented, however, by the various methods of seed treat¬ 
ment. 1 he germination of the spores has been reported by Wolff, 
Clinton, and others. Literature: 5, 6, 17, 18, 19,27, 67 77 78 92*
