120 MURRILL : POLYPORACEAE OF NORTH AMERICA 



types in all important particulars. The same species from Cuba 

 is labelled P. pcctinatus Kl. at Kew, though the latter plant does 

 not, to my knowledge, occur in North America. 



1 8. Pyropolyporus Jamaicensis sp. nov. 



A rather small fan-shaped plant, the upper layers of which are 

 dead and much cracked and roughened while the layers added 

 below are smaller each succeeding year. Pileus woody, applan- 

 ate, much thicker behind, 8 X 13 X 0.5-5 cm. ; surface uneven, 

 radiately rimose, dark brown to black ; margin ferruginous, velvety, 

 acute, becoming black, spreading and lobed, projecting 1—2 cm. 

 beyond the new layers: context woody, fulvous, 0. 5— i cm. 

 thick ; tubes stratified, separated by thin annual layers of con- 

 text, 0.2-0.7 cm. long each season, 7 to a mm., fulvous within, 

 mouths rounded or polygonal, hoary when young, edges thin, 

 acute, entire : spores globose or subglobose, thin-walled, smooth, 

 pale golden-yellow (probably darker in age), 5—7/^. 



Collected by Earle, at Port Antonio, Jamaica, November, 1902, 

 on an old stump of Psidmni. The spores of the present season 

 appear immature.
