Ustilago Crameri Korn. • 
Ustilago Crameri Korn., Fckl. Symb. Myc. Nacht., 2 : 11. 1873. 
Exsiccati: Ustilago Crameri Korn., on Setaria Italica , Griff., West 
Amer. Fungi, 9, Seym. & Earle, Econ. Fungi, Clinton Ust. Supp. C 66. 
Sori in the spikelets, infecting all of the spike, ovate, about 2-4 
mm. in length, chiefly destroying inner and basal parts ; spores red¬ 
dish brown, chiefly ovoid to subspherical though occasionally more 
elongated and irregular, smooth, with usually pitted contents, chiefly 
8-11 fx in length. 
Host: Setaria Italica , Conn., D. C., Ia., Ill., Ind., Mich., Ohio, 
N. Dak., S. Dak. 
This fungus sometimes causes damage to the cultivated millets. 
It has been reported only during recent years from this continent. 
The ordinary hot water method of seed treatment is a preventive. 
Brefeld has described its germination. Literature: 20, 27, 79, 171. 
Ustilago lycuroides Griff. 
Ustilago lycuroides Griff., Bull. Torr. Bot. Club, 31: 84. 1904. 
Sori in the ovaries, infecting only part of the spikelets, evident, 
spherical, about 1.5 mm. in diameter, covered with a greenish mem¬ 
brane bearing remains of styles at its apex, upon rupture disclosing 
a compact, dusty, black brown spore mass ; spores clear reddish 
brown, ovoid to subspherical, smooth but because of clear granular 
contents often appearing pitted, chiefly 10.5-14 /x in length. 
Host: Lycurus phleoides, Ariz. (type). 
This was found in small amount by Griffiths in the Santa Rita 
mountains near Greaterville, Ariz. The sori are not unlike those of 
Ustilago spermophora and U. sparsa , but the spores are entirely 
different. 
Ustilago Panici-proliferi P. Ilenn. 
Ustilago Panici-proliferi P. Henn., Bot. Gaz., 28: 274. 1899. 
Exsincati: Ustilago Panici-proliferi P. Henn., n. sp., on Panicum pro- 
liferum var. acuminatum , Syd., Ust., 212. 
Sori in the inner folded leaves and possibly also the aborted 
inflorescence, elongated, chiefly 3-8 cm. in length, often thickest at
