such a long pedicel as in this species. Puccinia Fcstuca; Plowr., it is true, 

 has a long pedicel (15-25// in length), but it is just about half the length of

5. Puccinia brevicornis S. Its. n. sp. — (PI. X. Fig. 7.) 



Urcdosori, 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, 14-21 X 12-16,« ; epispore comparatively thick; hyaline or some- 

 what yellowish ; paraphyses sometimes present, few in number, hyaline, 

 clavate or capitate, apex not thickened. 



Tfleutosori, hypophyllous, rarely epiphyllous ; small, oblong or sub- 

 linear, densely scattered, often confluent, loosely covered by epidermis or 

 naked with the ruptured remains, pulvinate, compact, conspicuouSv 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, 40-74 x 12-24/7. ; epispore rather thin ; pedicels very

Remarks. The present fungus seems to be restricted to Calaviagrostis 

 I'illosa Mut., which is quite common in Hokkaido. It is also found on Cala-

 on other species of the genus. Very short processes at the tip of the teleuto-
