122 REVISION OF THE NORTH AMERICAN HyYDNACEAE 
dently identical with the former in all essential features, but from 
its mode of growth the teeth were in general vertical to the sub- 
stratum instead of appressed or parallel to it. It appears to pre- 
sent all the characters of 7. croceum Schw. Schweinitz does not 
mention the habitat of his species further than that it was on dead 
wood. H. Schiedermayert Heuf. has never been reported except 
on apple-tree wood, and Heufler expressly states that it is found 
only on apple trees. 77. croceum Schw. appears to be the plant 
when growing оп a horizontal substratum and ZZ. Schiedermayeri 
Heuf. the same plant growing оп а vertical substratum. Schweinitz 
adds that “it spreads on wood more rarely to a remarkable length 
and breadth." А specimen found by David Griffiths on an apple- 
tree log at Fort Lee, New Jersey, and now in the museum of the 
New York Botanical Garden, measures a meter long by 15 cm. 
wide. It is of remarkably vigorous growth, and the tomentose 
character of the subiculum has extended in some degree to the 
teeth. 
The plant at first sight appears to have little in common with 
the preceding species of this genus. But the tuberculous thick- 
enings of the subiculum from which the teeth chiefly depend, and 
the white ovoid smooth uniguttulate spores seem to indicate its 
proper association in the genus Hericium. Тһе type specimen of 
Schweinitz is destroyed. Æ. eroceum Schw. has also been reported 
from West Virginia, Nuttall, and Maine, Harvey, but I have not 
seen these specimens. 
6. Hericium fimbriatum sp. nov. 
clearly distinguished branches anastomosing and forming thickened 
tubercles ; on the upper part of the plant these branches end in 
free fimbriate points about 1 mm. long; teeth pendent on the 
lower part of the plant and from the underside of the tubercles, 
terete to flattened, with whitish fimbriate tips, 3-10 mm. long, 
0.2-1.5 mm. wide; spores oblong, slightly curved, uniguttulate, 
2-2.5 by 4-4.5 p, apparently white or hyaline.
