A LICHEN NEW TO THE UNITED STATES. 
BY EUGENE A. RAU. 
Messrs. Eckfeldt <& Calkins, in their list of the Lichen-Flora of 
Florida, published in a recent number of this Journal, include some 
rare and interesting species. In regard to their No. 297, Trypcthelium 
heterochrous (Mont.) Tuck., very rare, introduced from Cuba, I would beg 
to remark that I collected this lichen in April. 1885, and sent specimens 
to Dr. Eckfeldt for identification. For the benefit of those who have 
opportunities to search for lichens in Florida, I will mention that this rare 
species was found along the shore«of Lake Osceola, Winter Park, in 
Orange county, growing upon living branches of Ilex Dahoon , Walt. 
NEW WESTERN UREDINEiE. 
BY S. M. TRACY AND B. T. GALLOWAY. 
Among the Uredinece collected last summer by Tracy & Evans, we 
find the following species which appear to be new: 
Uromyces Arizonica, Tracy & Gal.—I. Hypophyllous; spots con¬ 
spicuous, rather large, pale; recidia numerous, in definite clusters, scat¬ 
tered or often crowded, small, short, border often somewhat coarsely torn; 
spores subglobose, epispore thin, smooth, 18—21 II and III. Epi- 
phyllous; spots small, round or oval, reddish-brown, long covered by the 
epidermis.—II. Spores oval, pale, epispore thin, minutely echinulate, 
20 — 22 x 23—25 III. Spores globose or obovate, apex sometimes 
slightly thickened, brown, 20—22 x 25—27 p ; pedicel one and a half to 
two times the length of the spores, hyaline, tapering towards the base. 
On leaves of Eriogonum racemosum , Flagstaff, Arizona, June 27, 1887. 
Puccinia fragilis, Tracy & Gal.—III. Amphigenous ; sori scat¬ 
tered, long covered by the epidermis, which at length ts irregularly rup¬ 
tured ; spores broadly oval, dark brown, minutely roughened, 21—83 x 
30—34 ! J -, apex rounded, obtuse, not thickened, very slightly constricted, 
pedicel less than half the length of the spore, hyaline, very fragile. On 
leaves of Arenaria %mngens, Reno, Nevada, June 19, 1887. 
Puccinia caultcola, Tracy & Gal.—II. Hypophyllous ; sori very 
small, very numerous, covering the entire surface ; spores subglobose, 
epispore thick, minutely roughened, usually with one or more prominent 
vacuoles, light brown, 15—17 x 20—22 P-. —III. On stems; sori scat¬ 
tered, usually elongated, black; spores oval, not constricted, 25—27 x 
35—40apex much thickened, nearly hyaline, often with a similar thick¬ 
ening on one side of the lower cell, smooth; pedicel nearly hyaline, very 
long, several times the length of the spores. On Salvia lavceolata, Canon 
City, Colo., Aug. 21, 1887.
