No. 5.] USTILAGINEZ OF CONNECTICUT. 15 
/ 
Ustilago longissima (Sow.) Tul. Fig. 1. The sori form 
more or less distinct, linear strie from a féw mm. to length of 
leaf; the epidermal covering soon ruptures, and the dark 
reddish brown spore mass becomes scattered from the more or 
less shredded tissues. The spores are light brown, oblong, or 
more commonly ellipsoidal to spherical, smooth (or sometimes 
scarcely granular under an immersion lens), 4-8» in length. 
Host and Distr.: Glyceria grandis, Shaker Station, June 
29, 1903. 
This species undoubtedly has a wider Wistribution than in- 
dicated above. 
Ustilago Hordei (Pers.) Kell. & Sw. Fig. 46. The 
sori occur in every spikelet, forming an ovate, adhering, purple- 
black spore mass, 6-10 mm. in length, and rather permanently 
covered by the thin, usually transparent plant tissue. The 
spores are reddish brown, slightly lighter colored on one side; 
chiefly subspherical or spherical, smooth, and 5-ou, rarely 
(most elongated) 9-11p, in length. 
Host and Distr.: Hordeum vulgare, Whitneyville, Sept. 
24, 1902. 
This covered smut of barley is not nearly so common in 
this state as is the loose smut of the same host. 
Ustilago levis (Kell. & Sw.) Magn. Fig. 45. The sori 
usually occur in all of the spikelets, are more or less hidden by 
the enveloping glumes (which may be infected only at their 
base or in the interior), and form rather permanent, black- 
brown, semi-agglutinated, ovate spore masses 6-10 mm. in 
length. The spores are reddish brown, slightly lighter col- 
ored on one side, chiefly subspherical or spherical, smooth, 
5-9m, rarely (most elongated) 11, in length. 
Host and Distr.: Avena sativa, New Haven, July Io, 
July 28, 1902. 
This hidden smut of oats is not so common in our oat fields 
as is the loose smut, U. Avene. 
Ustilago Crameri Korn. Fig. 44. The sori occur in all 
of the spikelets of the spike, destroying especially the inner 
and basal parts, and form ovate dusty brown spore masses 
2-4 mm. in length. The spores are reddish brown, ovoid to
