of Cannabis sativa, was also recently found in this country by Air. T. Goto in the 

 Province of Shimotsuke. The fungus was first found in Switzerland, and described 

 by Otth^ in 1868, and later by MassalongO"-' in Italy. Unfortunately, the original 

 pajoers of these authors are not accessible here, and we cannot tell whether the 

 germination of its conidia was determined or not. At any rate, we hope we shall 

 be able to settle the question cluing the next season, and thereby may possibly be 

 able to add another species to the genus under consideration. 



Let us here enumei'ate the species of Pcronoplasniopara in Japan, giving its 

 hosts and distribution.
