had assumed their autumnal tints, but in some instances the green 
color had been retained about the margin of the spots. 
Septoria Pile, Thum. Spots small, scarcely one line in diameter, 
scattered, angular or suborbicular, definite, whitish, perithecia few, 
one to four, epiphyllous, minute, brown or blackish-brown ; spores fili- 
form, colorless, .0009 in. to 0015 .in. long, about .00008 in. thick. Living 
leaves of the stingless nettle, Pilea pumila. Sandlake. Sept. The spots 
are numerous but very small and the perithecia are scarcely visible to 
the naked eye. On the lower surface the spots are sometimes tinged 
with red or reddish-brown, 
Septogleeum Apocyni, ”. sp. (Plate 1, figs. 1-2.) Spots few, large, 
irregular, brown or blackish- brown ; nuclei few ; ; spores large, ‘subey- 
lindrical, rounded at the ends, colorless, .OO16 in. to .002 in. long, .0003 
in. to .0004 in. broad, three to seven-septate, each cell nucleate. Living 
leaves of Indian hemp, Apocynum cannabinum. North Greenbush. 
Sept. The spots at length become thick, brittle and almost black. The 
surrounding tissue fades to a yellowish hue. The septa of the spores are 
not always distinct but the nuclei in all the specimens examined are 
plainly visible. 
Vermicularia circinans, Berk. Surface of onions. Albany. Jan. 
Morthiera Thumenii, Cke. Living leaves of thornbush, Cratequs 
coccinea. Sandlake. Sept. ‘The specimens have the spores of this 
species but the perithecia are few and scattered as in A/. Mespili. 
Pestalozzia Stevensonii, Pk. (P. strobilicola, Speg.) Cone scales of 
Norway spruce.- Abies excelsa. Albany. September. 
Puccinia Thalictri, Chev. Living leaves of tall meadow rue, TVhalic- 
trum Cornuti, and early meadow rue, Thalictrum dioicum. Albany 
and Center. The spores of this species are scarcely distinguishable 
from those of P. Anemones to which species I formerly referred our 
specimens. 
Puccinia Cirsii, Lasch. Living leaves of thistles, Cirsium lanceolatwm. 
Knowersyille. October. 
Puccinia simplex, x. sp. Spots small, orbicular, scattered, brown 
or grayish-brown, with a purplish margin ; sori hypophyllous, hemi- 
spherical or depressed, compact, central, one on a spot, dark-brown ; 
spores fragile, ohlong-clavate, slightly constricted at the septum, pale- 
brown, .0016 in. to .002 in. long, .0004 in. to .0005 in. broad; pedicel very 
short. Living leaves apparently of some species of Geum. Albany. 
Sept. Though the spots are numerous, it is seldom that more than 
one sorus occurs on a single spot. 
Protomyces polysporus, 2. sy. Spots orbicular, thickened, generally 
convex on the upper surface, concave on the lower, pale-green or yel- 
lowish-green, becoming brown when old, two to four lines broad ; ; Spores 
numerous, crowded, globose or subglobose, subhyaline, or slightly 
tinged with green, 0005 in. to .0006 in. in diameter. Living leaves of the 
great ragweed, Ambrosia trifida. Albany. September. Leaves spot- 
ted by this fungus may be found from June till the close of the season. 
Usually the upper surface of the spot is convex and the lower concave, 
but sometimes this order is reversed. Tate in the season many of the 
spots are found to have assumed a brown or blackish-brown color. 
The spores are generally globose, but from their crowded mode of
