Described as follows from specimens collected on dead wood 

 in Venezuela by Fendler. 



" Effusa, indeterminata, tenuis, alutaceo, v. ochraceo-favida, 

 margine radiante, tenuiore, albido ; poris inaequalibu's, minimis, 

 angulatis, confluentibusque, dissepimentis tenuibus, acutis." 



Types have been examined at Kew and also in the Garden 

 herbarium. 



82. Poria ochracea sp. nov. 



Effused for many centimeters, continuous so far as the sub- 

 stratum will allow, inseparable, 1 mm. thick ; margin wide and 

 conspicuous in young stages, thin, appressed, membranous, to- 

 mentose, pallid, becoming much reduced in age ; context pallid, 

 not apparent in age ; hymenium somewhat uneven, appearing in 

 patches on the subiculum and becoming continuous, not glisten- 

 ing, ochraceous when fresh, isabelline in dried specimens ; tubes 

 large, firm, angular, very regular, thin-walled, entire, 1 mm. long, 

 2-3 to a mm.; spores smooth, pip-shaped, hyaline, 4.5 X 2 fi; no 

 cystidia observed. 



Type collected on a decayed fallen oak limb in mixed woods at 

 Crabbottom, Virginia, 3,000 ft. elevation, July 17-21, 1904, W.
