Puccinia aeluropi Ricker n. sp. — Sori amphigenous, 
mostly hyphophyllous, elliptical or oblong, often confluent; 
medosporo light yellow, elliptical or oblong, minutely verrucose, 
pores several and scattered, 22-30 fx; teleutospores clavate to ellip¬ 
tical or oblong, apex dark golden brown, rounded, thickened (up 
to ii/i), lighter below, slightly constricted, 19-25 x 30-54/x; pedi¬ 
cels equaling the spores, hyaline. 
On Aeluropus littoralis Pari, collected by Frick, Caucasus 
Mts., (type) ; Schrenck, Songoria, China, and on Aeluropus 
macrostachyus Hack., collected by A. V. Munro, Quetta, N. W. 
India. 
Puccinia kreageri Ricker n. sp. — Sori hypophyllous, in¬ 
conspicuous, ferruginous; uredospores globose to subglobose, 
22- 27/1, very light yellowish or almost colorless, wall thin, mi¬ 
nutely verrucose, pores several and scattered; teleutospores ob¬ 
long-ovate, 16-26 x 33-46/x, constricted at the middle, rounded at 
the base, yellowish-brown, wall medium thick, apex darker and 
thickened (up to 8.5/1) rounded or acute; pedicel tinted, short 
(up to 15/1), fragile, 8-9/i wide. 
On leaves of Festuca subulata Trin. (F. jonesii Vasey) 
Type No. 38 F. O. Kreager, Clark Springs, 10 mi. No. of Spo¬ 
kane, Wash., June 26, 1902. 
Puccinia paradoxica Ricker n. sp. — Sori hypophyllous, 
narrow, linear, inconspicuous, darkening the epidermis above; 
teleutospores golden brown, symmetrical, elliptical, constricted at 
the middle, conspicuously verrucose, 22-29 x 33"37i u 5 pedicel 
short, hyaline, deciduous. 
On Melica smithii (Porter) Vasey. Type collected by C. F. 
Wheeler, Chatham Station, Mich., August 22, 1900. 
The verrucose teleutospores at once distinguish this from 
any other Puccinia on the grasses. 
Puccinia piperi Ricker n. sp. — Sori hypophyllous, incon¬ 
spicuous, linear, often confluent, epidermis persistent; uredo¬ 
spores elliptical to subglobose, light yellow, echinulate, 16.5-23 x 
23- 26/1,; teleutospores clavate to cylindrical, golden brown, 22- 
26 x 53-62/1, apex usually flattened or sometimes rounded, not 
thickened, wall thin, slightly constricted at middle, covered with 
longitudinal angles giving a striated appearance; pedicel fragile, 
short, hyaline. 
On Festuca pacifica Piper ined. Type No. 6502 C. V. Piper, 
Eight dollar Mt., Oreg., June 12, 1904. 
At once distinguished from any species reported on Festuca 
or a related genus bv the longitudinal angles and absence of thick¬ 
ened apex of the teleutospore and hyaline pedicel. 
Puccinia leptospora Ricker n. sp. — Sori amphigeneous, 
mostly hypophyllous, conspicuous; spores golden brown at apex,
