Van Diemen's Land, R. Gunn, Esq. 



Pilei imbricated, decurrent behind, dimidiate, 1| inch 

 broad, \-l of an inch long, thin, coriaceous, but flexible and 

 very light, rugged behind, and irregularly zoned or sulcate, 

 at length nearly smooth, in front more even, clothed with 

 slightly tawny velvety down, which however, in old speci- 

 mens, entirely vanishes. Extreme margin thin and dark ; 

 substance pale, soft. 



Hymenium pallid, nearly white, but becoming rather 

 darker with age; pores small, l-60th of an inch in diameter, 

 angular, nearly entire or slightly toothed; dissepiments 

 thin. 



A very pretty and singular species, resembling somewhat 

 young specimens of Pol. cuticularis (Bull.), but not becoming 

 rigid like that, and a far smaller plant, not to mention the 

 different appearance caused by the zones, and the soft 

 velvety, not at all hispid covering. The pileus consists of 

 three distinct strata; the first spongy, beneath which is a 

 thin dark cuticle covering the pallid substance from which 

 the pores immediately spring. The colours are as nearly as 

 possible the same. There is an analogy between this species 

 and Stereum bicolor. Sometimes the apex is elongated and 

 the little pileus becomes triquetrous, as in that species.

On earth, mixed with particles of charcoal. Van Diemen's 

 Land, R. Gunn, Esq. 



Gregarious, here and there crowded, 1-2 lines broad, 

 orange-yellow, hemispherical, slightly concave, or quite flat, 

 with a delicate membranous edge, obscurely tomentose, 

 fixed to the soil by a little down. Asci cylindrical, obtuse. 

 Sporidia elliptic, attenuated slightly at either end, and con-
