Oct. 1902] North American Ustilagineae 137 
Cintractia is limited to species possessing- quite a different type 
of spores. 
USTILAGO ZEAE (Beckm.) Ung.—Hosts: Euchlaena 
luxurians, Ala., Ia., Ill., Kans., Wise.; Zea mays, common 
throughout N. Amer. 
USTILAGO PANICI-GLAUCI (Wallr.) Wint.—Ustilago 
neglecta Niessl, Rab. Fungi Eur. 1200. 1866. 
Host: Setaria glauca, Conn., Ia., Ill., Ind., Kans., Mass., 
Neb., N. H., N. J., N. Y., Ohio, S. Dak., Verm., Wise. 
USTILAGO UNIOLAE Ell. & Ev.—Host: Uniola gracilis, 
Miss., Tex. (type). 
USTILAGO ERIOCAULI (Mass.) Clint.—Cintractia erio- 
cauli Mass. Grev. 22:67. 1894. Ustilago eriocauli Clint., Rho- 
dora 3 182. 1901. 
Host: Eriocaulon septangulare, Mass, (type U. eriocauli 
Clint.), N. H., Conn. 
This was described by the writer in 1901 as a new species, 
as it was considered distinct from Cintractia eriocauli on Erio¬ 
caulon fenestratum, described by Massee from Madagascar. Since 
then 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, also, seems to come more 
propei ly under Ustilago than under Cintractia. 
USTILAGO ORNATA Tr. & Earle.—Host: Leptochloa 
mucronata, Miss. (type). 
USTILAGO SPOROBOLI Tr. & Earle.— Host: Sporob- 
olus junoeus, Miss. (type).
