S. ITÖ. 
spores are the characteristic by which this species can easily be distinguished 
from other coronate species of Puccinia. 
6. Puccinia Epigejos S. Itö n. sp.— (PL X. Fig. 8.) 
Uredosori, epipliyllous, sometimes hypophyllous ; minute, oblong or 
linear, scattered or gregarious, on discolored spots, sometimes confluent, 
loosely' covered by the epidermis, or naked, with ruptured remains, pulveru- 
lent, orange-colored. Uredospores ellipsoidal, oval or globose, echinulate, 
24-36 x 20-2 6// ; epispore thin, yellowish brown or hyaline ; paraphyses nu- 
merous, capitate or clavatc, hyaline or subhyaline, apex not thickened. 
Teleutosori, epiphyllous, rarely hypophyllous in severe cases, or on the 
sheath ; small, oblong or linear, scattered or gregarious, often confluent, 
reaching on the leaves 4 mm. in length, on the sheath 1.5 cm. long, naked, 
with ruptured epidermis, pulvinate, compact, conspicuous, black. Teleuto- 
spores cylindrical, long-clavate, apex thickened (4-6//), with the blunt, horn- 
like processes, base attenuated, not or slightly constricted at the septum, 
smooth, ferruginous or chestnut-brown, darker at apex, 36-92x14-20//; 
epispore thin ; pedicels very short, brown, persistent.

REMARKS. This fungus is found everywhere in Hokkaido, where C ala- 
rm grostis Epigejos Roth. var. densiflora Led. grows abundantly. 
Naked teleutosori are commonly epiphyllous. The teleutospores are 
longer and larger compared with those of Puccinia coronata. Especially 
the uredospores are the largest among the coronate species of Puccinia. 
ERIKSSON recorded Puccinia coronata as occuring on the present host-plant* 
His descriptions in regard to the measurement of the uredospore and the 
teleutospore do not coincide with those of our present species, which I have 
oonsequently treated here as a new species.
