March 1904] Notes on Californian Uredinece 
55 
dermis, spores very free (not crowded) ; spores reddish-brown, 
oblong, very slightly constricted at the septum, the two cells 
equal in size, walls thick, verrucose over the terminal cell and 
about half way down on the basal cell, base and apex round, a 
large low apical papilla frequently present but not at all conspicu¬ 
ous, 24-27.5 x 29-34 fi; pedicel hyaline, tapering downward, 37.5- 
44 fj, long, fragile, usually breaking off to about the length of 
the spore. 
Allied to P. menthae but differing in the aecidial stage in 
the strictly erect form of the distorted branches of the host, and 
the bulbous base of the aecidia; in the uredo stage in oblong 
spores, never globose; in the teleuto stage in the thick wall which 
is more thickly verrucose, the less prominent apical papilla, less 
marked constriction at the septum and greater size of the spores. 
I. II. III. On Micromeria chamissonis, Santa Cruz, June- 
July, 1903. I. and II. very abundant, III. rarely found. 
(Thompson) ; II. Big River, Mendocino County, June 14, 1903. 
(McMurphy.) 
Uromyces atro-fuscus Dudley & Thompson n. sp. 
I. Amphigenous; spots small, pale yellow; sori round to 
short elliptical, scattered or clustered but not at all confluent, 
standing out prominently from the host, brown-black. 
II. Spores scattered among the teleutospores, not abundant, 
elliptical, 16-17.5 x 25-26 fx, rather thickwalled, echinulate, germ- 
pores conspicuous, equatorial. 
III. Spores dark brown, obovate or not infrequently globose, 
more or less rounded, angular, 19-26 x 25-31 /a, wall thick, slightly 
more so at the apex, papillate, strongly so on the upper half of 
the spore but less so on the lower half; pedicel hyaline 2.5-3 
times the length of the spore, but fragile and usually breaking 
away near the spore. 
On Carex douglasii, near Palmers, Mariposa County, June 
22, 1894. (J. W. Congdon.) Carex usta, Bear Valley, San 
Bernardino County, Aug. 7, 1902. (L. R. Abrams, no. 2920.)
