species of Puccinia in our country on Arundinella anomala. On this point, I 
have sufficient reason to doubt its validity. 
I obtained, by the kindness of Prof. S. KUSANO, both of the type speci- 
mens on which Dietel based his determination. In the course of my study 
on both of these type specimens, my attention was drawn to the similarity 
between them. The pedicel of Puccinia Arundinellae anomalae is hyaline or 
light brownish yellow in color ; while that of Puccinia graminis is also light 
brownish or sometimes hyaline. Thus, to distinguish them by the color of 
the pedicel becomes totally impossible. 
The color of the pedicel is not an essential factor in the point of 
classification in Puccinia, at least, it is true in the case of Puccinia on 
Gramineae. For example, the pedicels of Puccinia erythropus , P. rufipes , 
P. Eulaliae and P. Arundinellae and also those of many other species vary 
pretty often in their color. So, simply from the color difference of the 
pedicels the so called Puccinia graminis on Arundinella may not be different 
from Peksoon’S Puccinia graminis. But uredospores which were acciden- 
tally found on the type specimen of the so called Puccinia graminis , differ 
utterly from those of P. graminis , but correspond exactly to those of the 
present species. I wish, for the reasons above mentioned, to include the 
Myogi specimen in Puccinia Arundinellae anomalae. 
As has already been mentioned, this species is distinguished from 
Puccinia Arundinellae of Himalaya by the slender teleutospores. But it must 
be remenbered that the dimensions of some of our species approach that of 
P. Arundinellae. Among specimens, collected at Garugawa, Tsurumi and 
other places, there were few spores which measure above 42 p. Generally, 
while young, the color of the teleutospore is light colored and slender in 
shape, but when ripened its color is darker and more or less roundish in 
shape. After all, our species may not be different from the Himalayan 
species. Further study is needed to settle this point.
