fibrous, tough-felty, brick red in upper part of pileus, more com- 
pact and darker below ; teeth slender, terete, dark reddish-umber to

Нав.: On earth in woods. Aug. 
RanGE: South Carolina, Ravenel ; Georgia, Underwood. 
Exsicc.: Ravenel, Fung. Car. Exsicc. 3: 17, as Hydnum fer- 
rugineum Fries. 
The type specimen is in the Underwood Herbarium, No 411, 
from Tallulah Falls, Ga. A part of the same collection is also in 
the herbarium of the New York Botanical Garden with the same 
number. The Ravenel specimens were distributed in his exsiccati 
as Hydnum ferrugineum Fries, but the plants are very distinct from 
that species in nearly every feature. The species is distinctly 
marked by its peculiar brick red color and its more or less dimidi- 
ate pileus. I take pleasure in dedicating this species to Professor 
Earle, whose excellent field notes have frequently aided in the dis- 
crimination of species in this family.
