which often shows faint concentric layers (innermost often marked 
off as an apparent endospore), chiefly 10-19 fx in diameter. 
Hosts: Andropogon argenteus , Tex. (type) ; A. hirtiflorus var. 
pubiflorus , Mex. ; A. perforatus, Mex.; A. saccharoides , Tex., 
Mex.; A. saccharoides var. leucopogon , Mex. (Chapala, Jalisco). 
This species is related through its very thick but much more reg¬ 
ular epispore to Tolyposporella Chrysopogonis though it does not 
form the definite spore balls of that species. Its spores have con¬ 
siderable resemblance to Kuntzeomyces ustilaginoideus , but upon 
pressure the outer coat does not break open and let out the unrup¬ 
tured spore as does that species, but the fissure extends clear 
through the spore. Kuntzeomyces also occurs in the ovaries and 
has its spore mass enclosed by a false membrane of sterile fungous 
cells. The germination of T. Brunkii is not known. 
Tolyposporella? Nolinae Clint, n. sp. 
Sori on the leaves, usually so crowded as to form a continuous 
and very conspicuous stratum of agglutinated black granular spores 
over the greater part of their surface ; spore balls rather indefinite, 
often apparently of two, three, or four spores adhering in various 
ways and often separating into single spores; spores olive black, 
oblong or ovoid to spherical, flattened where in contact, with thick 
smooth epispore, chiefly 11-18 /x in length. 
Host: JVolina microcarpa, Ariz. (type). 
The single collection of this known to the writer is in Professor 
Farlow’s herbarium, coming originally from the Gray herbarium. 
The specimen was collected in the mountains of Arizona in 1884. 
The whole plant was rather completely covered with the very evi¬ 
dent agglutinated spores. Cross sections of this material seem to 
indicate that the spores were formed on the surface of the leaves. 
They also appear to be formed from a gelatinized mycelium 
which would indicate that the species is a true smut rather than 
a Hyphomycete. The character of the sorus and the thick wall 
of the spores suggest a possible relationship to Tolyposporella 
Brunkii, though as yet the generic position is uncertain. It is 
hoped that further information may be gained from future collec¬ 
tions now that the species has been described. The spores have not 
been germinated.
