length, enclosed by glumes, soon rupturing and disclosing dusty dark 
brown spore mass; spores dark brown, usually ovoid to spherical 
or sometimes more elongated, prominently and abundantly echinu- 
late, chiefly 10-14 g in length. 
Host: Setaria glauca, Conn., Ia., Ill., Ind., Kans., Mass., Minn., 
Neb., N. II., N. J., N. Y., Ohio, S. Dak., Vt., Wise. 
This fungus is commonly known in this country as Ustilago neg- 
lecta. As the earlier varietal name of Wallroth was taken up by 
Winter it is used here though the writer is not in favor of the resur¬ 
rection of varietal names to take the place of well established names. 
This is one of the most common of the smuts and no doubt is to be 
found in every State where the host occurs-. The germination is 
described by Brefeld. Literature : 20, 129,

Sori in ovaries, showing between the glumes as slightly swollen 
ovoid bodies, about 2-4 mm. in length, rather firm, with semi-agglu¬ 
tinated or finally dusty spore mass ; spores dark reddish brown, 
oblong or ovate to spherical or occasionally angled and irregular, 
obscurely and minutely verruculose, 9-13 g in length.
