physes being not septated. Moreover, the uredospore of the present species 

 is the largest in the species of Puccinia growing on Bambuseae. 



Ure.Io3tage only, found in Japan.

 Syll., 11, 1895, (202) ; Sydow, Monogr. Ured., 1, 1904, (717) ; Fischer, Ured.

Hab. On Agrostis pcrcmians Tuck. 



Hokkaido. — Prov. Ishikari : Ebetsu (11. Sept. 29, 1907. S. IxG). 



Distrib. Europe, Japan, Siberia, India and Australia. 



Remarks. Our specimen has only the uredostage. A hyaline epi- 

 spore as well as general shape and size of the spore point to its identity with 

 Puccinia Agrostidis. But as there are no records about the number of 

 germ-pores of Puccinia Agrostidis, the exact identification is somewhat dif- 

 ficult. In ours there are 4-6 germ-pores. 



This fungus forms its yEcidium on the species of Aquilegia in Europe ; 

 but in our country, yEcidium on Aquilegia is not yet found.

 Distrib. Europe, Japan and India. 



Remarks. The teleutostage of this fungus has not yet been found in 

 our country. Consequently, it is somewhat difficult to settle exactly its 

 systematic position. However, the presence of paraphyses and the character 

 of the uredospores coincide very closely with the description of Puccinia 



Baryl.
