Among these species, those which are newly added to the Japanese 
mycological flora are 28 species and 1 variety, those which seem to me as 
entirely new and are described as such in this paper are 21 species and 1 
variety ; and 39 species and 2 varieties are endemic to Japan. 
I wish to express here my heartiest thanks to Prof. Dr. K. MlYABE 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. TAKAHASHI, J. 
HANZAWA and T. MlYAKE, 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. KuSANO, and that is the only 
specimen, I have examined. 
In 1905, DlETEL (9) noted the affinity of this species to Uromyces. 
Halstedii De Toni of North America. He remarked that it is hard to 
distinguish our species by uredospores only from Uromyces Halstedii. But in 
the case of teleutospores, their difference is evident. In Uromyces Halstedii , 
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 obovate or obovate,
