which I think is the first collection made in Hokkaido. McAltine (i) re- 

 marked, that the teleutosporcs of this species on Avciur fatita in Australia 

 are longer than those on Avcva sativa, reaching 86/< in length. In our 

 country, I have not been able to find any teleutospore on the former host- 

 plant, although the uredosporc-stage is found. On examining our specimens 

 on Avena sativa, however, I noticed the dimension of the teleutospore is 

 slightly longer than that of h'urope, the maximum length reaching 72// in 

 ours, while in European forms onl)^ 60//. In other respects, they thoroughly 

 coincide with each other. 



The scidial stage of this species as well as o{ Puccinia coronata is not 

 yet found in Japan.

Remarks. Dietel (2) elevated the Barclev's var. Jiiviah-nsis of 

 Piu'cinia coronata to a distinct specific rank on account of the smaller size 

 of aecidiospores (13-16X 10-15«) 'I'ld of naked teleutosori. 



In Japan, Prof. S. KUSANO collecti-d this species for the first time on 

 Bracliypodiiivi silvaticitvi in Prov. Izli, and DiETEL identified it with the 

 Himalayan species. In the present pajier a new host-plant, Brachypodinm 

 japoniciitn, is added to the fungus. 



An Mcid'mm on Rlavinus Japonicus, sent to DiETEL from our country 

 was considered by him as a stage of Puccinia himalensis (7). But after- 

 wards another ^cidium on Rhainnus japonicus was reported hy the same
