REVISION OF THE NORTH AMERICAN HYDNACEAE 173 
becoming lighter upward, rugose, central, 2-3 cm. long, 3-5 mm. 
wide ; teeth slender terete, tapering, acute, flexuose, cream-col- 
огей, 1.5-2 mm. long becoming shorter to the sterile margin, not 
decurrent ; spores subglobose, echinulate, white, 3.5 и wide; odor 
strong, heavy, resembling that of P. alboniger (Peck) and very 
persistent in the dried plant.

This species is almost an exact duplicate of P. tomentosus (L.) 
as recognized in this paper in most of its characters and perhaps 
should be regarded only as a variety of that species. Its larger 
size and especially its pronounced odor seem to warrant its recog- 
nition as a distinct species. I have never detected any odor in 
the smaller plant while the plants referred here retain the strong 
odor even after many months. 
The type specimen in the Schweinitz Herbarium is wholly 
destroyed and the above determination is based entirely on his 
description, with which these plants appear to answer in every 
particular. Schweinitz does not make mention of an odor. This 
omission can not be regarded as too important since tastes and 
odors were often unnoticed by the older mycologists. The size 
which he attributes to his plants would seem to preclude their 
being P. tomentosus (L.). 1t is very doubtful, however, if he 
would have made any distinction between the two species. Аз 
his description applies so well to the plants here under discussion 
and as it can not be shown that it pertains to any other forms I 
feel justified in retaining Schweinitz's name for the above species.
