198 DECADES or FUNGI. 



With the habit of Trametes hydnoides^ but allied to P. trichomallus^ 

 ftmalis^ etc., from all of which it is very distinct. 



574. P. (Placodermei) petalodes, n. s. ; subcarnosus; pileo cuneato- 

 flabelliformi castaneo zonato lineato rugose ; hymeuio umbrino ; poris 

 angulatisj dissepimentis tenuibus, coutextu albo. Spruce, ii. 36. 



Hab. On dead trunks. Panure. 



Pileus 3 inches across, 2 long, much attenuated behind, petaliform, 

 red-brown^ with numerous zones, rough, with multitudes of raised, ra- 

 diating lines, smooth ; substance white. Hymenium umber ; pores 

 minute, -^^ of an inch across, angular; dissepiment thin. In some 

 lights the hymenium has an olivaceous tint. 



A very beautiful species, allied to P. zonalis ; both are extremely 

 rigid. This is somewhat caruose when fresh, as is probably the case 

 with P. zonalis.

575. P. (Placodermei) martins^ n. s. ; pileo pulvinato dimidiato atro- 

 sanguineo zonis pallidis notato glabro ; contextu pallido senectute um- 

 brino ; hymenio pallido ; pons punctiformibus. 



Hab. On dead wood. Pauure. 



Pileus 3 inches across, pulvinate, dimidiate, nearly even, smooth, 

 deep black-purple, with pallid zones ; substance pale, iu age umber. 

 Hymenium concave, pallid, umber when old; pores minute, punctiform. 



A very singular species, remarkable for its peculiar colouring and 

 minute pores, which separate it at once from P. vulnerattis^ Lev.

 Altogether resupinate, extending a foot or more in length over the 



surface of the wood, with the border almost perpendicular, the surface 

 here and there rising into rounded hills with deep valleys ; sometimes 

 weighing a stone.
