REVISION OF THE NORTH AMERICAN HYDNACEAE 161 
pact, fibrous, hard, azonate, orange-brown ; stem slender, central 
or excentric, concolorous with pileus, bulbous at base with a 
compact mass of orange-colored spongy tomentum ; teeth short, 
decurrent, whitish becoming brown; spores subglobose, colored, 
4-5 м. wide. ) 
Нав.: On fallen cones of pine. Autumn. 
Rance: Idaho, Henderson. 
The type specimens are in the state herbarium at Albany. 
Only the one collection has been obtained and the above descrip- 
tion has been drawn up largely from the original account of Peck. 
The species is closely related to /7. floriforme (Schaef.) differing 
chiefly in its small size and peculiar habitat which is unusual in 
this genus. 
10. Hydnellum complicatum sp. nov. 
Plants terrestrial, mesopodous, complicated, medium size ; pileus 
expanded, convex, depressed in center, subregular to irregular, 
lobed, and complicated, thin, rigid, 4-7 cm. wide; surface more or 
less uneven finely pubescent to subglabrous, cream-colored to red- 
dish umber or purplish; margin thin, concolorous to reddish 
black, repand, sterile; substance fibrous compact, somewhat spongy, 
whitish to pale buff in upper part of pileus, harder, woody, sub- 
zonate in lower part and stem, becoming reddish toward the base ; 
stem short, deformed, somewhat bulbous at base with a compact 
somewhat spongy covering, 2-3 cm. long, 1 cm. wide; teeth short, 
slender, terete, decurrent, cream-colored at margin to fuscous 
toward stem, 3 mm. long or less; spores subglobose to ovoid, 
finely tuberculate, fuscous, 3.5 by 4.5 wide; odor slight but 
agreeable. бері. 
Rance: New York, Van Hook 8101. 
The type specimens are in the herbarium of Cornell Univer- 
sity, No 8191. The species is closely related to М. floriforme 
(Schaef.), differing chiefly in color, there being no tinge of yellow 
or orange, and in its smaller spores. The plant, though irregular 
and complicated, is more uniform and constant in its characters ; 
the surface of the pileus as a rule is more even and smooth. 
11. Hydnellum Earlianum sp. nov. 
Plant terrestrial, pleuropodous or somewhat mesopodous, small ; 
pileus expanded, convex to slightly depressed, roundish to dimidiate 
or reniform, 3-5 cm. wide ; surface slightly uneven, somewhat col- 
liculose, subpubescent to glabrous in places, brick red to brown
