is a new addition to our fungus-flora.

REMARKS. The present species was first found parasitic on Panicum 
prurientis on Oahu Island in Hawaii. 
Mr. T. YOSHINAGA kindly sent to me the specimens of the present 
species on Panicum sanguinale. The Japanese plant shows a great similarity 
to that of Oahu, and, in fact, no points of difference between them are to be 
seen as was identified by DlETEL (10). The teleutosori, it is said, were not 
found in the Oahu specimen. This is true also of our plant. The teleuto- 
spores are found mixed in the uredosori.

Distrib. Europe and Japan. 
Remarks. This species was at first included in Puccinia graminis , as 
there are apparently no distinct morphological differences between them. 
ERIKSSON and Henning (2) proved that this species has no relation to the 
.TEcidium on Berberis and that the uredospores have the hibernating power. 
From these physiological differences, these authors are led to consider them 
as distinct species. In 1907, Pole Evans (i) proved the existence of the 
decided morphological differences between them by his cytological investiga- 
tions of their uredo mycelia.
