DopDGE: STUDIES IN GENUS GYMNOSPORANGIUM 299 
Sixteen of the twenty-four plants inoculated gave positive 
results, showing seventy-nine separate infections. Six plants 
were not infected, two died. The time required for the full de- 
velopment of this species is only nine or ten months. 
The endeavor to infect Chamaecyparis with G. fraternum and 
G. biseptatum has not as yet resulted in success.
