such a long pedicel as in this species. Puccinia Festucce Plowr., it is true, 
has a long pedicel (15-25/* in length), but it is just about half the length of 
the pedicel of the species under consideration. Moreover, these two species 
differ from each other in so many points, that there is no need of ques- 
tioning their identity. 
5 . Puccinia brevicornis S. Itö. n. sp. — (PI. X. Fig. 7.) 
Uredosori, amphigenous, mostly hypophyllous ; small, oblong, or sub- 
linear, on the yellowish discolored spots, gregarious, scattered or somewhat 
arranged in lines, rarely confluent, naked, with the ruptured epidermis, 
pulverulent, orange-colored. Uredospores ellipsoidal, globose or obovate, 
echinulate, 14-21x12-16/*; epispore comparatively thick; hyaline or some- 
what yellowish ; paraphyses sometimes present, few in number, hyaline, 
clavate or capitate, apex not thickened. 
Teleutosori, hypophyllous, rarely epiphyllous ; small, oblong or sub- 
linear, densely scattered, often c'onfluent, loosely covered by epidermis or 
naked with the ruptured remains, pulvinate, compact, conspicuous* black. 
Teleutospores cylindrical, oblong-clavate, thickened (6-8/*) at apex, trun- 
cate, with the tubercular, short blunt horn-like processes or slightly undulate, 
base attenuated, not or slightly constricted at the septum, smooth, chestnut- 
brown, darker at apex, 40-74x12-24 /* ; epispore rather thin ; pedicels very 
short, brown, persistent.

Remarks. The present fungus seems to be restricted to Calamagrostis 
villosa Mut., which is quite common in Hokkaido. It is also found on Cala- 
magrostis canadensis cultivated in the College Botanical Garden, but not 
on other species of the genus. Very short processes at the tip of the teleuto-
