172 O’Brien: NoTES ON RESISTANCE OF CERTAIN FUNGI 
It will be noticed that the percentage of spores germinated 
does not always vary inversely as the length of the time of expo- 
sure, as would be expected. This discrepancy, however, can only 
be accounted for by the variation in resistance of individual spores. 
The results given in the table, especially those of experiments 
7, 9, 10, 12, 13, 22, seem to warrant the conclusion that in the 
five fungi studied, the spore, that is, the conidium, is no more re- 
sistant to moist heat than is the mycelium.
