REPORT OF THE DIRECTOR I918 61 



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. The spots 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 spot and the fungus occurs 

 on only a part of them. 



SCOLECOSPORIUM FAGI, Lib. 



Dead branches of alder, Alnus incana. Elizabethtown. Sep- 

 tember. 



The typical form occurs on beech, but I find no essential differences 

 in the form on alder. Massaria macrosperma, the ascigerous form, 

 has not yet been observed with us. 



PESTALOZZIA JEFFERISII, EUis. 



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 com cobs. Menands. September. 



MONILIA CINEREA, Bon. 



On plimis. Sandlake. Closely related to Monilia fructigena, 

 with v/hich the species has been united by some authors. 



RAMULARIA BARBARE.S, N. sp. 



Spots suborbicular, arid, white, generally bordered by a slightly 

 thickened brown line; fiocci 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. 



Living leaves of winter cress, Barbarea vulgaris. Highland Mills 

 and Port Henry. June.
