greenish-yellow margin. When very confluent the leaf at a little dis- 
tance presents the general dingy red hue of the spots. 
RamuJaria sambucina, 2. sp. Spots small, orbicular, scattered, pallid 
or reddish-brown, surrounded by a blackish-brown border ; flocci hy- 
pophyllous, tufted, short, irregular above, colorless ; spores oblong or 
subcylindrical, slightly narrowed at the extremities, colorless, .0009 in. 
to .0013 in. long, .0002 in. to .00025 in. broad, sometimes concatenate, 
rarely uniseptate. Living leaves of elder, Sambucus Canadensis.

Ramularia Impatientis, ”. sp. Spots few, suborbicular, reddish- 
brown, the margin subindeterminate ; spores epiphyllous, oblong, sub- 
acute, colorless, .0006 in. to .0009 in. long. Living leaves of touch- 
me-not, Impatiens fulva. Catskill mountains. Aug. This is a very 
obscure fungus, scarcely visible to the naked eye. The flocci and 
spores are generally more abundant near the margin of the spot, but 
this is not always well defined. 
Ramularia Rudbeckii, 7. sp. Spots variable in size, frequently con- 
fluent, angular, included by the veintets, brown; flocci hypophyllous, 
tufted, short ; spores subcylindrical, rounded at the ends, colorless, 
.0012 in. to .002 in. long, sometimes concatenate and obscurely septate. 
Living leaves of the cut-leaved cone-flower, Rudbeckia laciniata. 
Catskill mountains. Aug. ‘The flocci are even shorter than the spores. 
Cercosporella reticulata, 7. sp. (Plate 2, figs. 14-16.) Spots large, 
irregular, brown ; flocci amphigenous, short, tufted, nearly colorless ; 
spores numerous, very variable in length, bacillary or subcylindrical, 
colorless, .0016 in. to .0045 in. long, .00025 in. to .0003 in. broad, with 
three to seven septa. Living leaves of the tall goldenrod, Solidago 
altissima. Catskill mountains. Aug. ‘The large spots sometimes 
occupy nearly half of the leaf. They are dry and brittle. The pure 
white color of the fungus contrasts beautifully with the dark brown 
color of the spots. The spores are usually more abundant along the 
veinlets than elsewhere, and they thus give a reticulate appearance to 
the spot. Ihave referred the species to the genus Cercosporella, be- 
tween which and Cercospora there appears to be scarcely any differ- 
ence, except that of color.

Cercospora venturioides, ». sp. Spots generally large, irregular, 
sometimes confluent, dark-brown or cinereous with a broad blackish- 
brown margin ; flocciepiphyllous, tufted, short, subflexnuous, generally 
one or two-septate, united at the base, colored ; spores cylindrical or 
bacillary, at length three to five-septate, colorless, .0015 in. to .005 
in. long. Living leaves of siikweed, Asclepias Cornuti. Albany. 
Sept. The spots have a very dark or smoky-brown color which often 
becomes centrally cinereous on the upper surface. Sometimes there
