No. 5.] USTILAGINE® OF CONNECTICUT. 25 
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, oblorig to irregular polyhedral or subspherical, very 
minutely pitted, and 14-22» in length. . 
Host and Distr.: Juncus 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 Care-x. 
In North America it has been found chiefly on Carex Pennsyl- 
vanica, its host in this state. 
Schizonella melanogramma (DC.) Schrét. Figs. 9, 35. 
The sori form black, agglutinated, linear, elevated striz, I 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» 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.
