164 REVISION OF THE Хоктн AMERICAN HYDNACEAE 
of the European exsiccati. The icones cited represent our plant 
fairly well except that they all show too intense a blue color, but 
the color may have faded greatly in drying. It has not been my 
fortune to see the living plant. I have not been able to secure 
entirely satisfactory spore characters from the American speci- 
mens. Apparently the spores are pale in color, oblong, angular, 
and somewhat tuberculate. The plant appears to be distinctly 
northern in its distribution. 
14. Hydnellum cyaneotinctum (Peck) 
Hydnum cyaneotinctum Peck, Bull. Torrey Club, 30: 98. 1903. 
Plant terrestrial, mesopodous, light colored, medium size ; 
pileus obconic, depressed to convex, somewhat round to irregular, 
3-9 cm. wide, 2-10 mm. thick ; surface subeven to uneven, some- 
times somewhat colliculose, woolly pubescent to subfloccose, drab 
to isabelline becoming bluish toward the margin, fading to pale- 
blue or disappearing in drying, azonate; margin thick, rounded, 
sterile, becoming brown to black where rubbed ; substance spongy 
tomentose in upper part of pileus, compact, hard, and woody below 
and in stem, more or less transversely zonate, often tinged with 
blue; stem usually central, sometimes lateral, vertical, subterete, 
attenuate downward, but surrounded below by a bulbous mass of 
spongy tomentum that reaches nearly to the pileus and makes the 
stem appear deformed outwardly, surface brownish, about 1 cm. 
long by 7-10 mm. wide, bulbous base about I.5 cm. wide; teeth 
slender, terete, acute, shortening uniformly toward stem and 
margin, umber at base becoming lighter toward tip, 4-0 mm. long, 
0.25 mm. wide near base to 0.09 mm. wide at tip, decurrent to 
bulbous base ; spores oblong, coarsely tul late, often uniguttu- 
late, “ purplish brown in spore print," about 4 by 7 wide; basidia 
clavate, four-spored, sterigmata about 3.5 м long; odor farina- 
ceous, not strong. 
Нав.: On ground under Hemlock. July-Sept. 
RANGE: Maine, Anderson ; New York, Peck. 
The plant resembles in structure and consistency Я. velutinum 
and H. suaveolens, differing from the former chiefly in color, and 
from the latter both in color and odor. 
The type specimens were from Orris Island, Me. The New 
York specimens were found by Peck himself іп Warren County, 
and sent to the writer. They correspond in all respects to the
