ON THE UREDINEAE PARASITIC ON THE JAPANESE GRAMINEAE. 221 

 On Miscatithus sp. 



Honshü. — Prov. Mutsu : Gosliogawara (III. Oct, 1904. T. Kashivvai). 

 Distrib. Japan and India. 



Remarks. Barclay (3) tells nothing of the uredosori of this fungus ; 

 and his descriptions of the uredospores are made from those mixed in the 

 teleutosori. Uredosori of this species are hypophyllous, small, roundish, 

 oblong or linear in form, scattered or subgregarious on a characteristic dark 

 reddish spot, often confluent (6 mm in length), naked, with torn epidermis 

 on their margins, pulverulent, and brown in color. 



According to DiETEL (7), this fungus grows also on the leaves of /;«- 

 perata arnndiiiacca, in which case the uredospores are said to be slightly 

 smaller than those on Aliscanlhus sinensis. I have not been able so far to 

 find the present species on hnpcrata ariindinacea. Besides these two host- 

 plants, two other species are added in this paper, namely Miscantlnis 

 saccliavifloriis and J/, cofidensatus.

Remarks. I have not able to find any uredosorus of this fungus 

 in Hokkaido. Sydow (2) also remarks that the uredosori are ver>' scarce in 

 Europe, as the uredospores are soon replaced by the teleutospors, converting 

 them into teleutosori. 



The teleutospores of this species resemble somewhat those of Puccinia 

 Phragmitis, but they are generally shorter in length and broader in width 

 than those of the latter. These two species can readily be distinguished 

 ^rom each other by their uredospores. The uredospores o^ Puccinia Hloliniae
