spongy fibres, coated with a thin brownish, crustaceous bark, 
which is obscurely velvety. 
Pores 1-2 lines or more long, +s of an inch broad, angular, 
with the dissepiments thick, of the same substance as the 
lower coat of the pileus, which is paler than the upper and 
more tawny portion. Some are singularly wrinkled within, 
but this character is not constant. 
This is a most interesting addition to the vast genus Poly- 
porus. It clearly belongs to the same section as P. sacer, but 
is distinguished from all the species of the section except that, 
by its larger pores, and from Pol. sacer by its whole habit and 
nature. If the genus Trametes be finally established, this 
species must be admitted into it. 
20. Pol. (Pleuropus) infernalis, n. s. pileo flabelliformi in- 
tegro vel sub.lobato postice depresso tenui acuto demum 
suberoso-coriaceo glaberrimo, lzevi, basi exceptá striato-rugu- 
loso hepatico-nigro; stipite brevi laterali nigro sursum incras- 
sato punctato pulverulento; hymenio brunneolo: poris mi- 
nutis rotundis brevissimis; margine sterili.

Minas Geraes. Oct. 1840. 
Pileus 3£ inches broad, flabelliform, quite entire, or slightly 
lobed and crenate, marginato-depressed behind, suberoso-co- 
riaceous when dry ; ; extremely smooth and even, except at the - 
base, where it is pulverulent, and minutely rugulose and 
striate; of a black liver colour. 
Stem 1-1 inch long, À an inch thick, incrassated above, 
wrihkled longitudinally, and dotted with abortive pores, black, 
pulverulent, white within. 
Pores extremely shallow, punctiform ; hymenium brownish. 
This very distinct species is allied to Pol. varius and dic- 
tyopus.
