Decorticated wood of spruce, Picea Mariana. Adirondack moun¬ 
tains. September. 
This fungus forms patches several inches in extent. In external 
appearance it is suggestive of H. Artocreas, but it is much thinner, 
with shorter, more compressed and serrate teeth. This last character 
will also separate the species from H. fasciculare.

Hydnochaete n. gen. 
Subiculum effused, submembranous, floccose-tomentose, setige- 
rous; aculei subulate, setigerous. 
A hydnoid genus of which the typical species is like a resupinate 
Hydnum or more nearly like Caldesiella ferruginosa, but it differs in 
having its hymenium furnished with small smooth colored setae, 
which gives to the Hydnei a genus corresponding to Hymenochaete 
among the Thelephorei and to Mucronoporus among the Polyporei. 
Hydnochaete setigera n. sp. 
Subiculum thin, at first grayish-tawny or pale tawny, tomentulose, 
setigerous, the margin even and concolorous or sometimes somewhat 
fimbriate and whitish or grayish-white; aculei at first short, subconi- 
cal, blunt, pale tawny, becoming subulate with age, about one line 
long, villosely setigerous, persisting through the winter and becom¬ 
ing ferruginous or dark ferruginous, the plant becoming stratose by 
the development of a new subiculum and new aculei over the old 
ones each year, the setae simple or branched, .0016 to .0024 in. long, 
slender, sharp pointed; spores pale, subglobose or broadly elliptical, 
.0002 to .0003 in. long. 
Decaying wood of pine, spruce and hemlock. Adirondack moun¬ 
tains. July to September. I have also received specimens of the first 
year’s growth of this fungus from Professor Underwood, who col¬ 
lected them on the White mountains. 
Although forming strata, this species must be very distinct from 
the plant described by Rev. M. J. Berkeley under the name Hydnum 
stratosum. In its first year it is so similar in general appearance to 
Caldesiella ferruginosa Sacc., (. Hydnum ferruginosum Fr.) that by a 
careless observer it might easily be mistaken for it, but its paler color 
and the presence of setae will at once separate it.
