200 , DECADES OF FUNGI, 



Hab. On dead wood. Panure. 



Pileus 3 inches across^ 1^ long, dimidiate, subflabellifornij thin, 

 rigid, coriaceous, brown with darker zones, rough with radiating 

 raised processes, with a slight silky lustre ; edge acute, paler, passing 

 into white ; substance brownish, umber. Hyraenium white ; pores 

 punctiform, y^ of an inch across ; edge obtuse. 



Allied to P. caperatus^ but with none of its velvety clothing. The 

 pores in age lose somewhat of their white hue and brown umber. 



579. P. (Inoderraei) vespillonens, n, s. ; pileo tenui papyraceo refiexo 

 stygio zonato radiato-lineato subsericeo ; hymenio umbrino ; poris mi- 

 nutis subhexagonis. Spruce, n. 177. 



Hab. On dead trunks on the Eiver Uaupes. February, 1853. 

 • Pileus effused at first, orbicular, then confluent, several inches across, 

 reflexed, thin, flexible, papyraceous, dark brown, zoned, marked with a 

 few radiating lines, slightly silky ; extreme edge rufous. Hymeumm 

 umber ; pores subhexagonal, regular, -^ of an inch across ; dissepi- 

 ments thin ; edge entire. 



Eesembling somewhat P. caperatiis^ but much thinner and more 

 flexible, with regular, jubhexagonal pores. 



580, P. (Inodermei) xerophyllaceus^ n.s. ; pileo tenui rigido coriaceo 

 dimidiato e velutino glabro brunneo zonato riigosiusculo ; hymenio 

 brunneolo} poris punctiformibus. Spruce, n. 179. 



Hab. On dead wood. Panure. 



Pileus 3-5 inches across, 2 inches long, thin, rigid, coriaceous, rather 

 rugose, sometimes marked with little scabrous elevations, sometimes 

 nearly even, brown, repeatedly zoned, sometimes blotched ; edge acute ; 

 substance brown. Hymenium brownish ; pores punctiform, minute, 



2^ of an inch across. 



This species has many points of resemblance with P. Hostmanni and 

 P. capei'atna^ but the pores are far smaller than in either, and from the 

 latter it differs in the velvety down disappearing far sooner ; in ex- 

 ternal appearance it has much resemblance to the former,
