ey ArTHUR: NEW SPECIES OF UREDINEAE 
American species of Puccinia on Baccharis having teliospores 
smooth, this species is readily separated by the unusually thick 
walls of the teliospores. 
Puccinia pistorica sp. nov. 
Oand I. Pycnia and aecia unknown 
II. Uredinia hypophyllous, abundant, scattered, roundish, 
large, for some time partially covered by the overarching epider- 
mis, light cinnamon-brown; urediniospores globoid or obovate- 
globoid, 24-32 by 30-39u; wall pale yellowish, about 2 thick, 
sparsely and strongly echinulate, pores very indistinct, probably 
few. and scattered 
III. Telia amphigenous, in compact irregular groups, of 
varying size from 0.1 to I mm. across, chocolate-brown or blackish, 
usually shining; teliospores linear-oblong or oblong-lanceolate, 
small, 12-16 by 39-50u, obtuse or rounded above, narrowed 
below; wall smooth, chestnut-brown above, much lighter toward 
the base, I-1.5u thick at sides, 6—-12y thick above; pedicel tinted, 
slender, one-half length of spore or less. 
On Baccharis glomeruliflora Pers., Mt. Dora, Florida, March 
25, 1891, L. M. Underwood. ‘This species is distinct from all other 
species of Puccinia on Baccharis that the writer has examined, 
in the compact and glossy teliosori. The spores show no evidence 
of germination in the specimen examined. The material in hand, 
for which I am indebted to Prof. E. W. D. Holway, is scanty, 
however, and a more extended account must await the collection 
of better material, which should also supply the pycnial and aecial 
characters. The locality where the collection was made, as I 
learn from Mr. P. L. Ricker, is near Lake Dora, on the Tampico 
and Key West railway, and about halfway between the stations 
of Tavares and Sorrento. The fungus is not inconspicuous, and 
is likely to be found throughout southern Florida when searched 
for. 
Puccinia pagana sp. nov. 
III. Telia amphigenous, scattered, oval, 0.1-0.4 mm. broad 
by 0.2-0.7 mm. long, tardily naked, cinnamon-brown, somewhat 
pulverulent, ruptured epidermis falling away from above the sorus; 
teliospores oval or oblong, 18-23 by 27-35u, rounded or obtuse 
both above and below, not constricted at septum; wall cinnamon- 
brown, 1.5-2y thick, often slightly thickened above, 3-4u, some- 
times simulating a pale papilla, finely and inconspicuously verru-
