absence of the crown, and from the other remaining species it differs by the 
sorus long covered by epidermis. 
The shape of the teleutospores approaches nearest to that of Piiccinia 
glumarum from which our plant can easily be distinguished by the uredosori 
provided with numerous clavate paraphyses. This fungus is often found 
mixed with Puccinia Moliniae on the same leaf of the host-plant. 
22 . Puccinia Ishikawai S. Ito n. sp. — (PI. XI. Fig. 5) 
Uredosori, amphigenous ; very minute, oblong, scattered, on the dis- 
colored spots, often arranged in lines, sometimes confluent, loosely covered 
by the epidermis or naked, somewhat pulvinate, orange-colored. Uredo- 
spores, globose or subglobose, rarely broadly ellipsoidal, finely echinulate, 
22 — 32x20 — 28//; epispore hyaline or yellowish; paraphyses numerous, 
clavate, membrane thickened, hyaline, apex not thickened, 40 — 80 X 11 — 16//. 
Teleutosori, hypophyllous ; very minute, oblong or linear, scattered or 
subgregarious, arranged in lines, sometimes confluent, long covered by the 
epidermis, somewhat pulvinate, grey or blackish. Teleutospores, clavate, 
oblong-clavate or cuneate, apex truncate, obliquely pointed or wavy, 
thickened (4—6 /t), base mostly attenuated, not or slightly constricted at the 
septum, rusty or light brown, darker colored at apex, 28 — 48x12 — 20/4 
rarely 22 p. in width ; epispore thin ; pedicels short, brown, subdeciduous.

REMARKS. The present species resembles closely Puccinia pygmaea 
Eriks, in general characters. But they can easily be distinguished from 
each other by the color of the pedicel of the teleutospore. In Puccinia 
pygmaea the pedical is hyaline, while in our species it is brown.
