REVISION ОЕ THE NoRTH AMERICAN HYDNACEAE 129 
Plant pileate, iie solitary or imbricate ; pileus dimidiate, 
subconvex, or when mbricated deformed ; surface scabrous with 
strigose branched 1 гое fuscous, becoming blackish ; ; margin lobed; 
substance dry, fibrous, fuscous ; teeth terete, long, flexuose, forked 
near the margin, at first whitish variegated, becoming glaucous- 
cinereous. 
RANGE: Pennsylvania, Schweinitz. 
Icon.: Persoon, ор. с. pl. 14. f. 1. 
The species appears to be rare. It has been reported from 
New York, Peck, and from Massachusetts, Frost. I have seen 
only the Schweinitz specimen. This is peculiar and unlike any 
thing else I have seen. The plant throughout is very dark brown 
to blackish, the pileus excavated within into sponge-like cavities, 
the surface covered with a dense coating of slender dark hairs; 
teeth long, flattened and confluent so as to form tubes, the hymenial 
surface appears much like Fistulina. The specimen is only a frag- 
ment and old. Тһе description given above is adapted largely 
from Swartz. Persoon received a specimen of the plant from 
Swartz which he figured and described as Hydnum parasiticum L. 
But afterward Swartz pointed out that it was not the species of Lin- 
naeus, Регѕооп, however, retained the name, having transferred 
Hydnum parasiticum L. to another genus. Finally Swartz pub- 
lished the plant as Hyduum strigosum.
