ceous, repeatedly zoned, clothed with very short dense pubes- 

 cence, which in the darker zones, which are comparatively 

 smooth, is arranged in lines ; margin very slightly lobed, ex- 

 tremely thin and acute ; substance corky. Pores small, y^th 

 of an inch broad, irregular; dissepiments shortly dentate, 

 elongated ; margin barren, obscurely tomentose. Colour of 

 the whole plant, including the substance, of a more or less 

 pallid bay, like that of Thelephora laciniata. 



The nearest ally of this species is Pol. scytinus, described in 

 the present memoir. It is a smaller plant of a very different 

 form, not to mention other points of distinction.

Pileus 2 inches long, 2 \ inches broad, stemless, very thin, 

 lobed, coriaceous, marked with radiating fold- like lines, which 

 bear branched fascicles of fibres, and towards the base are 

 rough with isidiiform processes, reddish fawn-colour with a 

 satiny lustre. Substance fawn-coloured, silky. Pores rather 

 large, ^th of an inch broad, their edge toothed and elon- 

 gated ; margin extremely thin and acute, barren. Resembling 

 Pol. sericeo-hirsutus, Kl. {Hexagona sericea, Fr.), with some- 

 what of the aspect of Hexagona poly gramma, Montagne.

 gili villo strigoso cinereo vestito ; margine brunneo ; poris par- 

 vis subcinereis. " Boletus fragilis" Konig in Herb. Mus. Brit.

On trunks of trees, but not common. 



Stemless, imbricated, with the habit of a small Stereum. 

 Pileus one inch broad, half an inch long, thin, rigid, clothed 

 w T ith cinereous, rigid, matted, strigose hairs or bristles, with 

 one or two zones ; margin slightly lobed, striate, deep brown, 

 extremely acute, forming occasionally a crest-like ridge. Pores 

 small, y^th of an inch broad ; dissepiments rigid, cinereous, 

 wood-coloured. 



Two forms or rather states of this species occur : one, which 

 seems to be the more normal form, described above ; the other 

 from Ceylon, on charred wood, is more regular and occasion- 

 ally almost smooth, with the pores irregular and the dissepi- 

 ments obtuse. 



I am unable to point out any species to which it is nearly 

 allied, except perhaps P. cingulatus.
