44 THIRTIETH REPORT ON THE STATE MUSEUM. 
MARASMIUS PR&ZACUTUS Lilis. 
Trunks of dead alder trees. Mechanicsville. October. 
The lamella are sometimes quite distant and rounded behind. 
The stem which is remarkable for its thickness and peculiar 
shape and which constitutes the chief part of the young plant 
is pulverulent under a lens. 
PANUS TORULOSUS AY. 
Oak stumps. Greenbush. May. 
Bo.eEtus viscosus fost. 
Light sandy soil about pine woods. Center. October. 
PoLyporus ossEus Halchor. 
Old stumps in woods. Guilderland. October. 
Very rare. The pores in our specimens are a little larger 
than in an authentic specimen received from Dr. Kalchbrenner. 
PoLyPoRUS (ANODERMEI) DUALIS 2. Sp. 
Pileus dimidiate, sessile or sometimes produced behind into 
a stem-like base, convex or nearly plane above, somewhat 
uneven, rarely with a slight zonate appearance, single or ceespi- 
tosely imbricating, two to four inches broad, nearly as long, 
tawny or tawny-ferruginous, the margin sometimes paler ; flesh 
concolorous, the upper stratum of a soft spongy-tomentose tex- 
ture, the lower firm and fibrous ; pores minute, unequal, more 
or less angular, with thin dissepiments, whitish and denticulate 
on the edge, about equal in length to the thickness of the flesh 
of the pileus, dark ferruginous with a whitish or silvery reflec- 
tion. 
Dead trunks of spruce trees. Adirondack Mts. Also at the 
base of pine trunks. West Albany. August and September. 
The species is remarkable for the twofold character of the 
substance of the pileus, the upper half being of a soft tomentose 
nature, velvety to the touch and readily impressed by the finger 
nail, the lower half of a much firmer fibrous texture, smooth 
and subshining when cut or fractured. The plants are quite 
variable in size, shape and thickness of the margin which in 
some is quite thin, in others very obtuse In the latter the 
pores near the margin are often much enlarged or elongated 
so that the dissepiments appear like lamellee. The species is 
related to P. cuticularis Fr., but I have not found it with any 
appearance of a cuticle nor of a blackish color, nor with a fim- 
briated margin—characters said to belong to that species. 
Besides, that species is attributed to deciduous trees while our 
plant has thus far occurred on coniferous trees only.
