Cespitose. Ascomata carnose-gelatinous, light liver-color, 
1%4-1 cm. across, depressed in the center, contracted below into a 
short thick stipe; when dry, almost exactly the color of dried 
raisins, and more or less wrinkled and folded; asci cylindrical,

On leaves on Allium rigidum, Tulare Co., California, August, 
1891. ‘ Death Valley Expedition,” no. 1499, Coville & Funston. 
Aecidia amphigenous, on the tips of the leaves, thickly scat- 
tered; pseudoperidia hemispherical and closed at first, then 
erumpent and open, about 34 mm. diam., margin coarsely toothed ; 
aecidiospores obovate, elliptical or subglobose, 22-3015-204, 
smooth ; uredo-sori small (34-2 mm.), oblong or elliptical, soon 
naked, light yellow; uredospores elliptical, smooth, pale, mem- 
brane 2-3 thick. Teleutospore-sori punctiform, black, densely 
gregarious or confluent in crowded groups 34-1% mm. long by 
14-1 mm. wide, permanently covered by the epidermis. Teleuto- 
spores obovate or pyriform, 20-30X 15—22y, pale brown ; epispore 
smooth, scarcely thickened at the apex ; pedicels short (15-25/), 
hyaline, easily deciduous. 
A well marked species, easily recognized by the difference in 
color and structure of the uredo and telentospore sori.
