CLINTON: NORTH AMERICAN USTILAGINEAE. 
365 
Host: Eriocaulon septangulare, Conn., Mass, (type XJ. Erio- 
cauli ), N. H. 
This was described by the writer in 1901 as a new species, it 
being considered distinct from Cintractia Eriocauli as described by 
Massee on Eriocaulon fenestratum from Madagascar. Since then, 
however, specimens of the latter have been received from Massee 
and the two prove to be the same. Massee’s original description is 
at fault in that it gives the spores as smooth when they are distinctly 
verruculose. The fungus, too, comes more properly under Ustilago 
than under Cintractia. The writer has described the germination of 
the spores, literature : 28, 29. 
Ustilago ornata Tr. & Earle. 
Ustilago ornata Tr. & Earle, Bull. Toit. Bot. Club, 22: 175. 1895. 
Exsiccati : Ustilago ornata Tr. & Earle, on Leptochloa mucronata , Ell. & 
Ev., N. A. Fungi, 3340, Seym. & Earle, Econ. Fungi, 542. 
Sori in ovaries, rather inconspicuous, showing between the glumes 
as ovoid bodies 1-2 mm. in length • spores brown, chiefly subspher- 
ical or spherical, occasionally ovate or ovoid, very conspicuously 
verrucose or echinulate, 10—14 g in length. 
Host : Leptochloa mucronata , Miss. (type). 
Tracy and Earle state that the infected panicles remain more or 
less enclosed in the leaf sheaths. Through some error they described 
the infected ovaries as 20-30 mm. in length. This is another spe¬ 
cies whose germination has not been reported. Literature : 181. 
Ustilago Sporoboli Tr. & Earle. 
Ustilago Sporoboli Tr. & Earle, Bull. Torr. Bot. Club, 23 : 211. 1896. 
Sori in ovaries, ovate, about 2 mm. in length, forming rather firm 
compact spore masses; spores medium dark reddish brown, ovoid 
to spherical, with prominent coarse subhyaline tubercles, 11-15 g 
in length. 
Host: Sporobolusjunceus, Miss. (type). 
The coarse somewhat tinted and subacute tubercles are character¬ 
istic of this species which has only been reported from a single State. 
Its germination is not known.
