out on their exterior. The spores are reddish brown, oblong 
to polyhedral, chiefly irregular, smooth, but often showing 
darker lines on surface due to pressure of spore mass, and 12- 
18u, or (most elongated) even 22, in length. 
Host and Distr.: Cyperus filiculmis, North Haven, July 
26, 1902; Montowese, Sept. 14, 1903. 
This species was described originally from this state by the 
writer, having been found not uncommon on the sand plains 
near North Haven and Montowese. The affected plants look 
very much like those free from the smut, but can usually be 
detected by the darker aspect of the spikelets, which in this 
sedge are clustered into heads. 
Cintractia Montagnei (Tul.) Magn. The sori occur 
hidden in the ovaries, forming inconspicuous, oblong to sub- 
spherical, usually dusty spore masses. The spores are brown 
or brownish black, often compressed laterally, and so appear- 
ing ovoid to subspherical or occasionally more irregular and 
angled, smooth but minutely pitted, and 12-19, chiefly 13-16y, 
in length; they are very often provided with conspicuous, hya- 
line, wing-like bladders on either side. 
Host and Distr.: Rhynchospora alba, Berlin, Sept. 3, 
1902; Cheshire, Oct. 25, 1903. 
This is another smut readily overlooked, because the in- 
conspicuous sori are hidden by the floral bracts. 
Cintractia Caricis (Pers.) Magn. Figs. 8,27. The sori 
form subspherical bodies about 3-4 mm. in diameter in the 
ovaries; at first the sorus is protected by a white membrane 
of sterile fungous tissue, but this soon wears off, revealing the 
black, firmly agglutinated spore mass, the spores of which 
gradually ripen and wear off toward the interior. ~ The spores 
are black-brown, subopaque, chiefly irregular polyhedral, or 
occasionally ovoid to subspherical, smooth or pitted to gran- 
ular or even papillate, and 16-27y, chiefly 18-22y, in length. 
Host and Distr.: Carex Penysylvanica, Rainbow, June 6, 
1903; East Hartford, June 1, 1904 (Weatherby). 
This variable smut has been reported on a large number of 
Carex species in North America, but the above is the one upon 
which it commonly occurs. The illustration shows it in the 
ovaries at the base of the staminate spikelet of this host.
