7. Puccinia pertenuis S. Itö n. sp. — (PI. X. Fig. 9.) 



Tclciitosori, hypophyllous, rarely epiphyllous ; minute, oblong or linear, 

 densely scattered over the discolored portion, sometimes confluent, naked or 

 loosely covered by the epidermis, pulvinate, compact, conspicuous, black. 

 Uredospores mixed in the sori. 



Urcdospores ellipsoidal to globose, echinulate, 16-24 x i6-i8,«; epispore 

 thin, light yellowish ; paraphyses short, obovate-clavate, light brownish-col- 

 ored, apex not thickened, 30-55 x 20-26//. 



Telciitosporcs cylindrical, linear or oblong clavate, apex thickened, 

 coronate with numerous blunt somewhat long processes, base attenuated, 

 scarcely constricted at the septum, ferruginous, darker at apex, 40-72 x 10- 

 16// ; epispore very thin ; pedicels brown, short, subdeciduous.

Remarks. This species resembles Puccinia coronata in the position 

 and macroscopical appearance of their teleutosori, but they can easily be 

 distinguished from' each other microscopically. 



In the general form of the teleutospores, our plant resembles Puccinia 

 Epigcjos, from which it differs, however, in the position of its teleutosori and 

 in the smaller size of its uredospores. 



8. Puccinia Hierochloae .S. Itö n. sp. — (PI. X. Figs. 10, 11.) 

 Urcdosori, amphigenous, mostly epiphyllous, or on the sheath ; small 



oblong or linear, densely or loosely scattered over the surface, often con- 

 fluent, naked or loosely covered by the epidermis, pulverulent, orange-col- 

 ored. Uredospores ellipsoidal to globose, echinulate, 16-26.5 x 12-1S,«; 

 epispore comparatively thick, hyaline or yellowish ; paraphyses sometimes 

 present, clavate or capitate, hyaline, apex not thickened, 50-72 x 10-15«. 



Teleutosori, amphigenous, mostly epiphyllous or on the sheath ; small 

 or medium in size, oblong or linear, scattered or gregarious, often confluent 

 (2-4 mm.), loosely covered by the epidermis, becoming soon naked with 

 ruptured remains, pulvinate, compact, conspicuous, black. Teleutospores 

 cylindrical, oblong-clavate or linear-clavate, apex thickened, with the nu-
