REVISION ОЕ THE Ховтн AMERICAN HYDNACEAE 141 
The type specimens, which are from North Carolina, Atkinson, 
have the surface of the pileus covered with reticulate ridges which 
on their upper edges break up into coarse, strigose, branched, 
hair-like processes. Plants found at Port Jefferson, L. L, Peck 
and Earle 88о, differ from the above in having this characteristic 
reduced to a fine, soft, velvety tomentum, but careful examination 
shows it to be essentially the same structure. The plants of both 
the above collections appear in the dried state, light brown in color 
with little or no tinge of yellow. Similar plants found formerly 
by Peck in this same locality were referred to Hydnum mirabile. * 
But that species is described as having the lower part of the pileus 
and the stem woody to corky, whereas in the present plants there 
is no doubt of its fleshy character although the stem dries quite 
hard. The difference in texture between the upper and lower 
strata of the pileus does not appear so conspicuous a feature as 
Fries’s figure and description would lead one to expect. In our 
plant the tomentose feature appears to be wholly superficial. 
Specimens in the Ellis collection from New Jersey under the 
herbarium name Hydnum ochroleucum t have the tomentum of the 
pileus intermediate in coarseness between the type specimens and 
P. & E. 880. The color of the dried plants also is decidedly yel- 
lowish or ochraceous brown, as though this feature for some 
reason had been better preserved in drying. 
There seems good reason, as was suggested by Peck, to refer 
these plants to Hydnum acre Quél. The only marked difference I 
find in the descriptions is that the European plant is smaller. But 
in the absence of authentic specimens of the latter plant it seems 
best to treat S. cristatus ( Bres.) as a good species.
