REPORT OF THE STATE BOTANIST. 101 
Cercospora Comari, 2. sp. 
Plate 1, figs. 1-3. 
Spots irregular, indefinite, sometimes confluent, reddish-brown ; flocci 
minutely tufted, amphigenous, slender, flexuous, colored, .o05 to .0065 
in. long, .ooo2 broad ; spores clavate, obscurely two to three septate, 
slightly colored, .o02 to .003 in. long, .o003 broad in the widest part. 
Living leaves of Potentilla palustris (Comarum palustre). Karner. 
July. 
Cercospora Majanthemi, ck. 
Living leaves of two-leaved Solomon’s Seal, Majanthemum bifolium. 
Caroga. July. 
Our specimens vary a little from the description of the species to 
which we have referred them, but they are probably only an American 
variety of the species. The spots are margined with red or brownish- 
red and the spores are nucleate, but I have not seen them septate. They 
appear to rise from a minute reddish or pink-colored tubercle. 
Hadrotrichum lineare, w. sp. 
Plate 1, figs. 4-6. 
Flocci amphigenous, densely czspitose, subflexuous, black, forming 
oblong or linear black sori; spores terminal, ovate, oblong-ovate or 
oblong-pyriform, colored, .00065 to .oorr in. long, .o0045 to .c0055 
broad, sometimes becoming constricted in the middle. 
Living and dead leaves of Calamagrostis Canadensis. Adirondack 
mountains. June. 
- I have referred this fungus provisionally to the genus Hadrotrichum, 
although it does not rigidly agree with the description of that genus, in 
which the flocci are characterized as short. In our plant they are .oo2 
to .o0o3 in. long. By their tufted mode of growth they appear to deviate 
from the allied genus Monotospora. ‘The spores, so far as observed, do 
not become definitely uniseptate, though in a few instances the endo- 
chrome seemed to be divided and the spores constricted in the middle 
as if about to multiply by division. They are colored, but are slightly 
paler than the flocci.. These form definite linear or oblong sori or 
patches which are often parallel and sometimes repeatedly interrupted 
and look like a series of dots. At first sight they might be mistaken 
for some species of Puccinia. 
Cenangium balsameumn, 2. sp. 
Receptacle single or czspitose, sessile, erumpent, externally black or 
blackish, greenish-yellow within, disk plane or convex, blackish bay-red 
or greenish-yellow when moist, black and somewhat uneven when dry ; 
asci clavate, .004 to .0055 in. long, .o005 to .ooo6 broad; spores oblong 
or subfusiform, sometimes slightly curved, simple, greenish-yellow, .0008 
to .oor2 in. long, about .0003 broad. 
Dead branches of balsam, Abies balsamea. Caroga. July. 
This has probably been confused with C. ferruginosum, which it 
somewhat resembles, but the spores are much larger than the dimensions 
ascribed to the pores of that species, and larger than the spores in the 
specimens of that species in Mycotheca Universalis.
