NEW CALIFORNIAN UREDINEZ. 951 
sori numerous, scattered, minute, ochraceous, pulverulent. 
Uredospores ovoid or elliptical with a pale brownish, echinu- 
late membrane perforated by numerous germ-pores, which 
are distributed over the whole surface, 34—44 x 21—31 y. 
Teleutosori minute, pulvinate, pale. Teleutospores clavate 
or oblong, rounded at the little thickened apex, attenuated or 
rounded below, constricted at the septum, pale brownish, 
smooth, 56—74 x 23—32 y. Pedicels firm, mostly longer 
than the spores, inflated, often very considerably. The teleu- 
tospores germinate directly after their maturation without 
any period of rest. 
On Baccharis viminea. Pasadena, Cal., Aug., 1893, leg. 
McClatchie (No. 359).—This fungus has most resemblance to 
another Californian species on Baccharis pilularis, viz.: 
Puccinia evadens, Hark. In the “ Provisional Host-Index of 
the Fungi of the United States” of Farlow and Seymour 
Puceinia evadens is also noted as occurring on Baccharis 
viminea. But there can be no doubt as regards the specific 
difference of the forms. The teleutospores of P. evadens, 
have a broad cap-like apical thickening of ca. 8y, whereas in 
P. Baccharidis the thickened part of the apex is minute and 
only 3—4 y thick. Another difference consists in the shape 
of the spore stalks, which in P. evadens are not inflated. I 
have not been able to examine whether the uredo stage exhib- 
its any difference. 
Puccinia mellifera, D. & H. Aicidia hypophyllous on 
yellow or brown spots, isolated or composed into little 
groups, cinnamon colored, dusty. Pseudoperidia elongated, 
deeply slit, very perishable; peridial cells cylindrical, some- 
what rough or nearly smooth, easily separable from one 
another. A®cidiospores ovoid or subglobose, finely verrucose, 
brownish, with numerous germ-pores, 29—40 x 24—29 w. 
Teleutospore layers mostly epiphyllous, roundish, ca. 1 mm. 
in diameter, naked, black-brown. Teleutospores elliptical, 
rounded on both ends, slightly constricted in the middle, 
little thickened, if atall, at the apex, smooth, chestnut brown, 
40—50x28—35 y. Pedicels of moderate strength, measuring 
up to 80 4.
