the edge, and the substance and exposed portion of the pileus 
are dark brown. The dissepiments, also, in Dr. Montagne's 
fungus are thicker. 
There is always some doubt about resupinate species, if 
they exceed a line in thickness. There is, however, no known 
species of which this can be a state. The same also may be 
said of Dr. .Montagne's Pol. tephroporus, though it comes 
very near to resupinate specimens of Pol. caperatus, which I 
have from British Guiana. 
— 82. Trametes incana, n. sp.; pileo laterali duro suberoso 
explanato dealbato glabro, contextu albo; stipite brevissimo

On dead trunks, Ohio, n. 225. T. G. Lea, Esq. 
Pileus 8 inches broad, 44 inches long, attached by a very 
Short, lateral disciform stem, flabelliform, smooth, opake- 
white, zoneless, or with a few obscure depressions, and short, 
radiating grooves; substance hard, corky, white, 14 inch 
thick; margin subacute. Hymenium even of a very pale 
ochre; pores small, one-sixtieth of an inch in diameter, 
mostly roundish, here and there forming linear or curved 
sinuses, Sometimes the stem is accidentally elongated. 
Resembling somewhat Dedalea ambigua, and certain states 
of Lenzites repanda, but distinct from either. 
—83. Dedalea ambigua, n. sp.; pileo suberoso crasso con- 
vexo azono dealbato glabro; hymenio subalutaceo ; pors 
parvis sinuosis acie obtusa. 
On dead trunks, Ohio, n. 117. T. G. Lea, Esq. 
Pileus sessile, dimidiate, 6 inches broad, 3 inches mdi; 
14 inch thick, convex, zoneless, opake-white, as if white- 
washed, smooth, or most minutely pubescent in the younger 
parts only, of a hard, corky texture, white within. Margin 
at first very obtuse. Hymenium rather concave, of a pale 
tan-colour, pores small, narrow, sinuated, moderately deep, 
dissepiments obtuse. 
This species approaches closely to some states of Lenzites 
repanda, Fr., but it is a true Dedalea, the pores being at first
