fore in cross-section appearing oblong to circular according to 
view, smooth, 11-16/4 in length. 
Host: Rhynchospora sp., Mex. 
This form is described from specimens issued in Sydow's 
Ustilagineen no. 22o from Mexico. The synonyms given are 
those that have been assigned by others, the writer not having 
seen type specimens of these. This Mexican collection, at least, 
seems to deserve specific distinction from both Cintractia axicola 
and Cintractia leucoderma. From the former it differs not only 
in the host and part infected but also in its darker colored spores 
and from the latter in the position and size of the sorus and in its 
smooth spores.

Hosts: Rhynchospora gigantea, Porto Rico (type C. krugi¬ 
ana), Rynchospora sp., Mex.; PRhynchospora, Cuba, San Do¬ 
mingo (type).

vanica, Conn., Ia., Ill., Mass., Mich., N. Y.; Carex sp., Calif., 
Colo., Ind., Mich., Ore., Utah, Wyo. 
The writer has received a specimen of the type of Ustilago 
ambiens from Karsten and it proves to be this species.

Toni, Sacc. Syll. Fung. 7 2 :5 oi. 1888. Mykosyrinx cissi Beck, 
Ann. Natur. Hofmus. Wien, 9:123. 1894. 
Hosts : Cissus acida, Porto Rico; C. erosa, Porto Rico; C. 
sicyoides, Fla., Bahamas, Jamaica, Porto Rico, San Domingo

lago aristidae Pk., Bull. Torr. Bot. Club 12:35. 1885. 
Hosts: Aristida basiramea, S. Dak.; A. longiseta robusta. 
Neb.; A. purpurea, Neb.; A. rusbyi, Ariz. (type) ; A. scheideana, 
Ariz.; Aristida sp., Kans., Tex. (type U. aristidae). 
With age the spore-balls very easily separate into the indi¬ 
vidual spores and then the fungus may be taken for an Ustilago.
