F 



563. P. (Pleuropus) hemibapJius, d. s. ; pileo reniformi subcroso 

 brunneolo radiato-rugoso zonato; stipite valido umbrino pniinoso; hy- 

 menio albo concavo ; poris minutis punctiformibus ; contextu pallido. 



Hab. On dead wood. Panure. 



Pileus 3 inches across, corky, reniform, radiato-rugose, opaque, 



, brownish, zoned, zones sometimes impressed ; margin nearly entire. 



Stem 2-2-^ inches high, f-i inch thick, thickened at the base, umber, 



pruinose. . Hymenium concave, pearly white, forming a little raisdd 



border all round ; pores minute, punctiform. 



This has the habit of PorotJielium rugosum, and agrees with it in 

 many of its characters ; but the hymenium is very different, and the 

 pileus is not so rugose.

 rugoso sulcato-zonato atro-purpureo subtiliter velutino lineatoque ; sti-
