MARSONIA POPULI, Sacc. 
Living leaves of Populus monilifera. Menands. July. 
CORYNEUM TUMORICOLA, N. sp. 
Spots scattered, suborbicular, pallid with a reddish-brown border, 
apparently produced by insects; heaps epiphyllous, minute, dot- 
like, unequal, black; spores oblong, triseptate, colored, .0004 to 
.0005 inch long, 00016 broad, at length breaking from the 
sporophores. 
Living leaves of elm, Ulmus Americana. Adirondack moun- 
tains. July. Thespots in this instance, as in that of Phyllosticta 
tumoricola, appear to be due to the stings of insects. A central 
aperture or puncture is visible in the spots and the fungus occurs 
on only a part of them. 
SCOLECOSPORIUM FAGI, Lib. 
Dead branches of alder, Alnus incana. Elizabethtown. 
September. 
The typical form occurs on beech, but I find no essential 
differences in the form on alder. Alassaria macrosperma, the 
ascigerous form has not yet been observed with us. 
'PESTALOZZIA JEFFERISII, Ellis. 
Leaves of wild grape, Vitis riparia. Gansevoort. September. 
The fungus occurs on spots which are apparently produced by a 
sterile Rhytisma. 
MONILIA MARTINI, E. &S. 
Old corn cobs. Menands. September. 
MONILIA CINEREA, Bon. 
~On plums. Sandlake. Closely related to Monilia fructigena, 
with which the species has been united by some authors. 
 RAMULARIA BARBAREZA, N. sp. 
Spots suborbicular, arid, white, generally bordered by a slightly 
thickened brown line ; flocci amphigenous, either short and branched 
or longer and simple ; spores oblong or cylindrical, often catenulate, 
rarely uniseptate, .0004 to .0009 inch long, .00012 to .00016 
broad.
