dactyloctaeniophila is quite like it in macroscopic appearance. 
Though the species was first described by Underwood in 1897 it 
was issued years before in Ravenel’s Fungi Amer. Exs., no. 790, as 
Ustilago destruens Schl. Its germination has not yet been reported.

Sori in the ovaries, usually infecting only a few in the spikelets, 
ovate, small, 1—2 mm. in length, sometimes bearing remains of 
unaffected part of ovary at apex, protected by a thin membrane ; 
spores light brown, ovoid to subspherical, usually prominently echin- 
ulate, chiefly 8-11 p in length.

This smut is closely related to Ustilago pustidata and Ustilago 
sparsa. It was first found by Curtis and the only specimen in his 
collection is from Society Hill, South Carolina, collected in 1849. 
The name was published first in his Catalogue, in 1867, but without 
description. Specimens were first issued by Ellis in N. A. Fungi, 
no. 1098, in 1883, while the first description of the species is appar¬ 
ently that given in Saccardo’s Syll. Fung., 7 2 : 466, in 1888. The 
germination of the spores, apparently, has not been reported. 
Ustilago Boutelouae Kell. & Sw. 
Ustilago boutelouae Kell. & Sw., Journ. Myc., 5 : 13. 1889. 
Sori in the ovaries, 2-4 mm. in length, more or less concealed by 
the glumes but at maturity becoming evident on the rupture of 
covering membrane by the dusty olive brown spore mass ; spores 
reddish brown, chiefly ovoid to spherical, conspicuously echinulate, 
8—13 p in length. 
Host: Bouteloua oligvstachga, Ivans, (type), Okl. 
This species has spores much like those of Ustilago spermophora.
