112 REVISION OF THE NORTH AMERICAN HyDNACEAE 
floccose-tomentose or subscrobiculate at the center of the disk, 
subsulcate-zonate, castaneous or darker near center to light cream- 
color or whitish at margin; margin thin, substerile ; substance 
fibrous tough, thin; stem slender, terete, attenuate downward to 
a common floccose-tomentose base imbedded in the substratum, 
subpubescent, cream-colored above to glabrous dark reddish brown 
below, 1-1.5 cm. long, 2-7 mm. wide; teeth slender terete, acute, 
scarcely decurrent, whitish to cream-colored, 2 mm. long and 
less ; spores subglobose, echinulate, white or hyaline, 3.5-4 м wide.

The species resembles in many respects Hydnellum zonatum 
(Batsch) but is clearly distinct in color and especially widely 
separated by its spore characters. 
There has been some doubt among mycologists as to the 
identity of H. tomentosum L. In fact from the two-line description 
in the Species Plantarum it is not possible to decide what species 
the name represents, but in Fl. Suec. 383, the description seems 
clearly to indicate the above plant.
