170 REVISION OF THE NORTH AMERICAN HYDNACEAE 
determinations, if we may judge by the following comments made 
by him on a specimen much resembling H. Carbunculus (Secr.): 
“This is undoubtedly the American representative of our Euro- 
pean Hydnum graveolens Delast. and we have but one species of 
that name. It has the same odor. Тһе only strong scented опе 
besides is Æ. suaveolens which is blue internally. І agree with you 
it is not like Fries' figure nor like our specimens," etc. 
While under this name in the collections there are many very 
distinct forms which doubtless represent well-marked species they 
are in such confusion that it is impossible to separate them satis- 
factorily. Determinations by Bresadola, Patouillard, and others 
do not agree even with respect to the same plants. Careful dis- 
criminating field work on these forms will I am confident result in 
the separation of several distinct species. It is important as a basis 
of this work, however, that P. graveolens (Delast.) should be 
clearly defined. 
5. Phellodon putidus (Atkin.) 
Hydnum putidum Atkinson, Mushr. Edib., Pois., etc., 199. 1900. 
Plant terrestrial, mesopodous, irregular, large, brown with broad 
white margin; pileus broad, depressed or subinfundibuliform, 
irregular, lobed, 8-12 cm. wide; surface uneven, at first sub- 
tomentose or pubescent becoming smooth, subzonate, brown to 
blackish-brown toward center, white to cream-colored toward 
margin; margin thick, obtuse, sterile; substance spongy whitish 
in upper part of pileus, tough, more compact but not very hard, 
darker in lower part, whole plant light and pithy when dry, pliant 
when moist ; stem stout, irregular or deformed, surrounded by a 
thick spongy tomentum ; teeth long, slender, terete, acute decur- 
rent, at first white or cream-colored changing, through salmon or 
directly, to grayish-brown, 4 mm. or less long; spores globose, 
echinulate, white, 3—4 # wide; odor fetid when fresh disappearing 
in drying.

The type plants collected at Blowing Rock, N. C., are in Cor- 
nell University Herbarium No. 4334. These are the only speci- 
mens I have seen of this species, which is well marked and clearly 
defined. The above description is drawn up largely from Atkin-
