Cintractia Junci (Schw.) Trel. Fig. 28. The sori are 

 linear, usually surrounding the pedicles or peduncles for half 

 or more of their lower length, occasionally developing in the 

 basal parts of the flowers ; they form a black, rather firmly ag- 

 glutinated spore mass. The spores are black-brown, sub- 

 opaque, oblong to irregular polyhedral or subspherical, very 

 minutely pitted, and 1 4-22/1 in length. 



Host and Distr. : Juncns tenuis, Westville, June, 1891 

 (Thaxter) ; Milford, June 26, 1894 (Sturgis), July 27, 1902; 

 Whitneyville, June 20, 1902. 



This was one of the first smuts reported from North Amer- 

 ica, having been described by Schweinitz from Carolina in 

 1834. The figure shows one of the peduncles smutted for half 

 its length. 



Schizonella Schrot. 



The sori form black agglutinated spore masses in the 

 leaves. The spores are united in pairs (formed by internal 

 division of a mother cell), and often become laxly connected 

 by their bulging contiguous surfaces, or even entirely separ- 

 ated ; they are of reddish brown color and of small or medium 

 size. Figs. 9, 35. 



Only one species, with a variety, is known for this genus, 

 but it has a wide distribution on various species of Carex. 

 In North America it has been found chiefly on Carex Pennsyl- 

 vania!, its host in this state. 



Schizonella melanogramma (DC.) Schrot. Figs. 9, 35. 

 The sori form black, agglutinated, linear, elevated striae, 1 or 

 2 mm. long, or, by terminal fusion, of considerable length, 

 chiefly on the upper sides of the leaves. The spores are dark 

 reddish brown, often with the cells entirely or partially sep- 

 arated by the bulging out of their contiguous surfaces, chiefly 

 ellipsoidal to hemispherical, or, when separated entirely, poly- 

 hedral or subspherical, and 8-12/x in, length. 



Host and Distr. : Carex Pennsylvanica, Westville, July 

 12, 1902 ; Whitneyville, May 4, 1903. 



This is a species found chiefly in the spring; it probably 

 has a much wider distribution than indicated here.
