Ramularia Norvegioe n. sp. 



Spots irregular, often confluent, brown or reddish-brown ; flocci tufted, short, 

 blunt ; spores narrow, oblong or cylindrical, straight, .0005-.0012' long, 

 .00015' broad, the longer ones sometimes uniseptate. 



Living leaves of Norwegian cinquefoil, Potentilla Nortegica. West 

 Albany. June. 



Ramularia Fragari^: n. sp. (Plate II, figs. 15-17.) 



Spots small, suborbicular, arid, whitish surrounded by a purplish boarder ; 

 flocci short, tufted; spores cylindrical, straight or slightly curved, .0008'-.0012' 

 long. 



Living leaves of the common strawberry, Fragaria Virginiana. Knowers- 

 ville, Center and Carlisle. May and June. 



The spots are often sterile . so that it is sometimes difficult to find the 

 spore-bearing fungus. 



Ramularia liweola n. sp. 



Spots suborbicular, sometimes confluent, brown, adorned with fine concen- 

 tric lines; flocci obscure, tufted, hypophyllous ; spores slender, cylindrical, 

 obtuse, often uniseptate, .0005 -.0008' long. 



Living leaves of dandelion, Taraxacum Dens-leonis. Greenbush. July. 



The fungus is extremely minute and scarcely visible to the naked eye. 



Ramularia Plantaginis n. sp. 



Spots suborbicular, sometimes confluent, brown ; flocci tufted, amphige- 

 nous; spores oblong or cylindrical, obtuse, .0008'-. 0016' long, .0002-.00025' 

 broad, sometimes uniseptate. 



Living leaves of English plantain, Piantago lanceolata. Carlisle. June. 



Glomerularia gen. nov. 



Flocci short; spores adhering together in masses. 



This is a genus of Hyphomycetes, order Mucedines, and is apparently 

 allied to the genus Ramularia, from which it is distinct not only by the shape 

 of the spores, but also by their peculiar habit of adhering together in heaps 

 or masses. Although but the single species here described is known to me, 

 it is so unlike any other fungus with which I am acquainted that I am com- 

 pelled to make a genus for it. 



Glomerularia Corni n. sp. (Plate II, figs. 10-14.) 



Spots orbicular, sometimes confluent, brown, surrounded by a purplish 

 margin ; flocci short, obscure, hypophyllous, bearing irregular suboval masses 

 of white spores ; spores globose, rough, .0004'-. 0005' in diameter, the 

 masses .0012-.0016' long, .0008-.00P broad, usually containing about six 

 spores each. 



Living leaves of dwarf cornel, Cornus Canadensis, Catskill and Adi- 

 rondack Mountains. July. 



In the small spots the whole under surface is whitened by the masses of 

 spores, in the large ones the spore masses form marginal bands or patches.
