80 DECADES OF FUNGI. 
* P. rufescens, Fr. Ep. p.433. Hook. fil., No. 26, 27. 
Has. On dead wood. 3-5,000 feet. One specimen springs from 
the pileus of P. hirsutus. 
Three distinct forms occur, two from Darjeeling, the third from 
Jillapahar, differing (I believe according to the height at which they 
grow) in the substance of the pileusand decomposition of the pores. 
No. 27 is hard when dry, fuliginous, velvety, with the pores sinuous; 
No. 26 is rufous, more decidedly tomentose, and has the pores lamellate ; : 
. a third form has the texture still softer, the down more decided, the 
colour still more rufous, and the hymenium assuming the appearance 
of that of a Lenzites. English specimens of Polyporus rufescens differ 
greatly in density of texture at the same elevation. 
* P. oblectans, Berk. in Hook. Lond. J ourn. vol. iv. p. 51. Hook. 
fil., No. 118, cum ic. 
Has. On dead wood. Sikkim, 7,500 feet. Very rare. 
A single specimen only occurred, with the hymenium imperfect. 
The pileus shines more than in the Ceylon or Swan River specimens, 
but this is apparently the only difference. The pores in this and the 
allied species vary greatly in form, according: to age and circumstance. 
* P. xanthopus, Fr. Ep. p. 437. 
Has. On dead wood. Darjeeling, 7,000 feet. Below eui. 
Hot valleys, 3—4,000 feet. 
"The specimens have the pores rather larger thin usual. They ex- 
hibit beautifully the downy dise from which the stem — rises in 
perfect specimens. 
336. P. (Mesopus) maculatus, n. s. ; albido-lutescens ; pileo coriaceo- 
carnoso depressiusculo maculato, margine subrepando ; stipite centrali 
deorsum attenuato; poris amplis margine laceratis longe decurrenti- 
bus. Hook. fiL, No. 3, cum ic. 
Has. On trunks of living trees. Darjeeling, 8,000 feet. April 1848. 
. Inodorous, coriaceous but brittle. Pileus about 2 inches across, plane 
or slightly depressed, dry, spotted with obscure adpressed scales ; sub- 
stance thick, white. Spores 1} inch high, attenuated below, 3 of an 
inch above, smooth at the base. Pores large, 1 line across, running 
nearly to the base of the stem; edge more or less lacerated, by no 
means obtuse or entire. 
Nearly allied to P: Michelii, Fr., but differing in its lacerated not 
entire pores. P, lentus, Berk., which is also nearly allied, and of
