North American Ustilagineae

new. It was collected by Dr. Palmer in Mexico. The pustules 
are l ireer and more clustered than those formed by Thecaphora 
pilulaeformis. The hyaline intersporal areas are peculiar and it 
is probable that by further gelatinization of these the spores be¬ 
come separated. In the younger conditions the spore-balls are 
imbedded in the prominent semi-gelatinized mycelium. The ger¬ 
mination of the species is not known.

Pk., Bot. Gaz. 5 135. 1880. Tolyposporium aterrimum Diet., Nat. 
Pflanzenf. I 1 **:i4 < 1897. 
Hosts : Carex adusta, la.; C. pennsylvanica, Colo, (type S. 
•atrum), Kans.; Carex sp., Ia. 
There is some doubt as to the true generic position ol this 
species. Dietel places it under Tolyposporium.

This species is related through its very thick but much more 
regular epispore to Tolyposporella chrysopogonis though it does 
not form the definite spore-balls of that species. Its spores have 
considerable resemblance to Kuntzeomyces ustilaginoideus but the 
outer coat, upon pressure, does not break open and let out the 
.unruptured spore as does that species but the fissure extends 
clear through the spore.
