No. 5.] USTILAGINEH OF CONNECTICUT. 19: 
Host and Distr.: Panicum Crus-galli, Conn. (Setchell) ; 
Savin Rock, Sept. 14, 1902; Westville, Sept. 12, 1902. 
This species and the next are very closely related, and oc- 
cur on the same host, but are rarely, if ever, found together. 
Fig. 53 shows a portion of the flower panicle with a single un- 
usually large sorus. 
Ustilago Crus-galli Tr. & Earle. The sori form nodules 
often encircling the leaf node, or more rarely occur in place 
of inflorescence, infecting both leaves and stem; they are one 
to several cm. in diameter and protected by a tough hispid 
plant membrane, which on rupture discloses an olive brown 
spore mass. The spores are reddish brown, ovoid to spherical, 
occasionally more elongated, rather bluntly echinulate or even 
verruculose, and 10-14 in length. 
Host and Distr.: Panicum Crus-galli, New Haven, Sept. 
II, 1903. 
Only a single specimen of this smut was found on a culti- 
vated variety of this barn-yard grass grown at the Experiment 
Station. 
Ustilago strizformis (West.) Niessl. Fig. 51. The 
sori occur in the leaves, rarely in the inflorescence, forming 
short linear striz, or by terminal fusion reaching several cm. 
in length, and laterally are often so crowded as to cover most 
of the leaf; at first they are covered by the epidermis, but this 
soon ruptures, and the dusty brown-black spore masses be- 
come scattered from the shredded tissues. The spores are red- 
dish brown, vary from ellipsoidal to spherical, or occasionally 
irregular, are prominently echinulate, and 9-14» in length. 
Hosts and Distr.: Agrostis alba var. vulgaris, Whitney- 
ville, July 20, 1902, May 9, 1903; Centreville, June 12, 1904; 
Phleum pratense, Whitneyville, Bae 9, 1903; New Haven, 
May 16, 1903. 
Both of these hosts are economic eae grown for pasture 
or hay, but so far the smut has been found on them in this state 
only in door yards. Fig. 51 shows the leaves of Agrostis alba 
var. vulgaris shredded by this fungus. 
Ustilago Zez (Beckm.) Ung. Figs. 2, 55. The sori 
break out on any part of the host, often forming prominent 
smut balls, though these vary from a few mm. to over a dem.
