Among these species, those which are newly added to the Japanese 

 mycological flora are 28 species and i variety, those which seem to me as 

 entirely new and are described as such in this paper are 21 species and i 

 variety ; and 39 species and 2 varieties are endemic to Japan. 



I wish to express here my heartiest thanks to Prof. Dr. K. MlVABE to 

 whom I am indebted for his many valuable suggestions and his constant kind 

 direction. To the gentlemen, above mentioned, who have kindly helped me 

 by sending valuable and interesting specimens, I express my sincere thanks. 

 I wish also to acknowledge my indebtedness to Messers. Y. Takahasiii, J. 

 HanzAWA and T. MlVAKE, who have kindly helped me in many ways.

Remarks. I was fortunate enough to examine the original specimen of 

 this species by the kindness of Prof S. KU.SANO, and that is the only 

 specimen, I have examined. 



In 1905, DiETEL (9) noted the affinity of this species to Uroiuyces 

 HalstcdU De Toni of North America. He remarked that it is hard to 

 distinguish our species by uredospores only from üroiiiyces Hahtcdii. But in 

 the case of teleutospores, their difference is evident. In Uromyces Hahtcdii, 

 the paraphyses are hyaline, the teleutospore wedge-shaped at base, and 

 broadly truncate at apex ; the general shape is triangular, and it is larger in 

 measurement ; and the pedicel is shorter ; while in Uromyces ovalis, the 

 paraphyses are light brown, the teleutospore rounded or attenuated at base 

 and rounded at apex, the general shape being spherical obovatc or obovate.
