Gloeosporium falcatum Dearness & House, sp. nov. 

 Spots gray with a darker, ridged border and surrounded by an 

 indefinite, reddish, somewhat transhicent margin, 3 to .7 mm broad. 

 Acervuh epiphyUous, concolorous, scattered, best observed with 

 reflected Hght under the microscope, 90-150 /x. Spores falcate, 

 hyahne, acute at one or both ends, grumous and guttulate, 



24-32 X 8-12 [X. 



On hving leaves of Benzoin aestivale (L.) Nees. 

 Black lake near Catskill, N. Y. H. D. House, August 21, 1915. 

 Type in the herbarium of the New York State Museum. 



The specimens are perhaps rather immature and might possibly 

 develop septa in the spores, in which case it would be a Marsonia 

 related to M . daphnes. 



Gloeosporium hydrophylli Dearness & House, sp. nov. 



Spots slaty gray, subcircular when not marginal, mostly about 

 I cm broad, concentrically ridged when seen through a lens, becom- 

 ing dry and brittle and breaking up. 



Acervuli innate, often found in sections where their positions 

 were not discovered with the lens. Spores hyaline, 5-9x2-2^ fx, 

 nucleate at each end.

 at first suggested a species of Gloeosporium but Professor Dear- 

 ness, who identifies the species, notes that spores were found with a 

 hyaline septum and that there is a thin pycnidial wall. The zona- 

 tion, colors and spore measurements agree with the description of 

 Ascochyta wisconsina, and differs from A . e b u 1 i 

 Fckl. described on Sambucus in Europe.

 (Sacc. Syll. 5:713. 1887)
