REPORT OF THE STATE BOTANIST. 139 
ACALYPTOSPORA POPULI, 2. sp. 
Spots irregular or suborbicular, reddish-brown, definite; spores 
epiphyllous, oblong-ovate or subfusiform, scarcely pedicellate, 
colored, one to two-septate, -0008’—-0009' long, -0003’—-00033’ 
broad. 
Living leaves of the great-toothed poplar, Populus grandiden- 
tata. Center. July. 
The fungus was found on the leaves of young trees. ‘The 
affected tissues soon break up and fall out. The spores appear to 
form gummy patches or reticulations slightly darker than the 
general color of the spot. 
MACROSPORIUM TRANSVERSUM, 2. Sp. 
Spots pale, at first greenish-yellow, then whitish and arid, some- 
times with a reddish-brown border, forming transverse bands on 
the leaf ; flocci tufted, subflexuous, septate, colored, -0016’—- 0025 
long, -00016’—-0002' broad; spores apical, oblong-ovate or 
oblong-clavate, either obtuse at both ends or acuminate or sub-~ 
rostrate at one end, three to five-septate, with here and there a 
longitudinal septum, colored, -001’—-002' long. 
Living leaves of Carex stricta. West Albany. May. 
The discolored spots are often sterile. Frequently the leaves are 
narrowed at the affected spots by the contraction of the tissues 
and are thereby weakened and abruptly bent. 
ALTERNARIA TENUIS, ees. 
Inner surface of old pods of silkweed, Asclepias Cornutt. 
North Greenbush. November. 
In some specimens the rostrum of the spores is not dilated at 
the apex as figured by Corda, but as the two forms grow inter- 
‘mingled in the same patch they are evidently all one species. The 
spots, as I find them, are generally thinly effused and indefinite, 
not definite as figured in ‘‘Mungi Italict.” 
ELLISIELLA CAUDATA, Sacc. 
Dead leaves of broom-grass, Andropogon pe Center. 
May. 
This genus appears to me to be founded on very slight characters. 
It scarcely differs from Colletotrichum, except in having the spores 
longer pointed. 
BoTRYTIS CERATIOIDES, 2. sp. 
Flocci white, flaccid, suberect, obscurely septate, simple or 
sparingly branched, obtuse and sometimes bilobed at the apex, 
the upper part densely pulverulent with spores; spores globose, 
smooth, subochraceous or isabelline, -00025’'—-0003’ in diameter. 
Decaying wood of hemlock, Adies Canadensis. Albany. June.
