REVISION OF THE Мовтн AMERICAN HYDNACEAE 143 
thin, sterile, decurved; surface subpubescent to smooth, some- 
times with small innate scales, light brown or ochraceous brown 
with darker areas ; substance fleshy, somewhat tough, light brown, 
lighter than the surface; stem subflexuose, somewhat inclined, 
excentric to central solid, subeven, abruptly narrowing below to a 
slender root-like base, 2-2.5 cm. long, 1-1.5 cm. wide ; teeth 
fine, terete, tapering, decurrent more or less scatteringly to the 
root-like base, seal brown to flesh color at the tips, when dry a 
uniform tawny brown, short teeth scattered about among the 
long, 1.5-2 mm. long, 0.1-0.2 mm. wide, 3 or 4 to one milli- 
meter; spores subglobose, tuberculate, 4—5.5 wide, brown ; taste 
mild; odor of slippery elm.

The type specimen is European. The American plants differ 
from Kalchbrenner's figure and description only in color, being of 
a tawny or ochraceous brown to umber rather than “ fuligineo- 
violascens cum tinctura passim vinoso-rubella.” But Ellis notes 
in his specimens “а slight purplish tinge to the pileus " and says 
the flesh has a “slight violet tint when freshly broken." This 
seems to confirm our determination of the plant as Kalchbrenner's 
species. Ellis regarded the plant as an undescribed species, but I 
do not find that he ever published it. Bresadola* says that 
Kalchbrenner's figure is poorly colored and rather represents 
Hydnum amarescentem Quél. His own figure does not so well 
represent our plant either in color or form. 
The radicating stem is a very marked feature of the plant. 
Specimens occasionally show a tendency to develop scales. Ellis 
remarks that the plant “is about the size and much resembles Æ. 
imbricatum,” doubtless having reference to the plant described in 
this paper ав 5. Fennicus Karst. The plant does have a close 
resemblance to the latter species, and in New York I found the 
two species closely associated, but 5. fuligineo-violaceus was quite 
distinct and definitely smaller in size.
