E,EMAKKP : - This is also one of tlie species newly added to our flora. The 

 funtius is eoniparatively abundant in the vicinity of Sapporo. Comparing our plant 

 to the Xortli American specimens of Ph. Riibi-Idad (Pers.) AVint. preserved in our 

 College Herbarium thei-e remains hardly any doubt as to their identity. Fh. Bubi- 

 Jdad (Pers.) Wint. differs from PJi. Rnhi (Pers.) Wint. by the number of the 

 .(■ells and by tie shape of the papillum of the teleutospores. Also in spite of the 

 many apparent simiiürities existing between this species and Ph. Rvbi-^japonici n. 

 sp., they differ fi'om each other in the length of the pedicel, and also in tlie form 

 of the uppermost cell.

KEMARKS : — Tlu! fungus under consideration was at first taken to be iden- 

 tical with Ph. Bubi-Idad (Pers.) Wint. But after all we are rather inclined to 

 regard it as a new species. Our present type is easily distinguished' from Ph. 

 Ilubi-Idad fPers.) Wint. by the shorter pedicel and also by the acute papillum of 

 its teleutospore. Besides Mubu,^ japoniom, being herbaceous, varies widely in its 

 habit from RubiDi' Idaei's var. ."sfrigo.^u.s.
