13. Inoculation Experiments. 
These experiments were undertaken over and over again in order to 
determine the parasitic habit of this fungus. Although I had failed in many 
cases with these inoculations, I succeeded at last under a special condition to 
produce the disease artificially. The most important reason for such failures 
seems to be the powerful resisting power of the seedlings, which were used in 
these experiments for convenience' sake. 
* I = Pycnidial stage. II = Ascosporous stage.
