with a whitish tomentum; spores white, globose, minutely echinulate, 
.00016 in. broad. 
Pileus 6 to 18 lines broad ; stem 6 to 10 lines long, about 2 lines 
thick. 
Gregarious among fallen leaves in woods. Port Jefferson. July. 
This species appears to be very much like the preceding one, from 
which it is separated by its smaller size and the paler brownish or 
ferruginous-brown substance of the pileus and stem. 
Hydnum spongiosipes n. sp. 
Pileus convex, soft, spongy-tomentose, but tough in texture, fer¬ 
ruginous-brown, the lower stratum more firm and fibrous, but con- 
colorous; aculei slender, 1 to 2 lines long, ferruginous-brown, becom¬ 
ing darker with age; stem hard and corky within, externally spongy- 
tomentose, colored like the pileus, the central substance often trans¬ 
versely zoned, especially near the top; spores subglobose, nodulose, 
purplish-brown, .00016 to .00024 in. broad. 
Pileus 1.5 to 4 in. broad; stem 1.5 to 3 in. long, 4 to 8 lines thick. 
Woods. Rensselaer and Saratoga counties. August. 
This plant was formerly referred to Hydnum ferrugineum Fr., to 
which it is closely related and of which it may perhaps be a variety. 
But having observed it for several years I find it constantly differing 
from the Friesian plant as figured and described in leones Hymem 
omycetum, in having the pileus convex and the stem covered with a 
dense spongy tomentum, colored like the pileus and quite distinct in 
texture from the hard central part. The figure of H. ferrugineum 
shows a depressed pileus and a stem paler in color and of a uniform 
texture that is without any external tomentose coating. Nor does 
the description ascribe such a character to the stem of the European 
plant. 
Hydnum mirabile Fr. 
A plant answering fairly well to the description and figure of this 
species was found in the sandy soil of woods near Port Jefferson. Its 
structure is of that peculiar character ascribed by Fries to his species, 
and which apparently suggested the specific name, mirabile. Its odor 
when the flesh is cut or broken, is farinaceous and its taste is also
