SOUTHERN POLYPORES n 



discolored within, mouths angular, somewhat irregular, 3-4 to a 

 mm., usually becoming irpiciform at an early stage, edges acute, 

 dentate, becoming lacerate, white to yellowish or umbrinous. 



Extremely common throughout on dead deciduous trees, often 

 covering entire trunks. It is easily mistaken for one of the 

 Hydnaceae. 



4. CORIOLELLUS Murrill 



Hymenophore small, dry, annual, epixylous, semiresupinate ; 

 surface anoderm, usually azonate; context white, thin, fibrous 

 to corky; hymenium concolorous; tubes thin-walled, usually 

 rather large and irregular, dentate, but not irpiciform; spores 

 smooth, hyaline. 



Pileus white or pale-isabelline. I. C. Sepium. 



Pileus fulvous to latericeous. 2. C. serialis. 



1. CORIOLELLUS SEPIUM (Berk.) Murrill 



Pileus small, dimidiate, laterally connate, narrowly attached 

 when young, becoming decurrent and often effused, 0.5-1 X i~3-5 

 X 0.2-0.5 cm.; surface white or pale-wood-colored, finely tomen- 

 tose to glabrous, subzonate, smooth or broadly radiately fur- 

 rowed; margin thin or tumid, entire to undulate; context white, 

 1-2 mm. thick, soft-corky; tubes white, 2-3 mm. long, mouths 

 angular, uneven, irregular, sometimes slightly sinuous, 1-2 to a 

 mm., edges thin, undulate to dentate, white; spores oblong, 

 12 X 5/x. 



Common throughout on structural timber and other dead 

 wood, especially that of deciduous trees. 



2. CORIOLELLUS SERIALIS (Fries) Murrill 



Pileus corky to woody, extensively effused, resupinate or 

 shortly reflexed, seriately elongate, laterally connate, the reflexed 

 portion very narrow, o- 1 X 1-1.5 X 0.3-0.5 cm. ; surface uneven, 

 subzonate, appressed-tomentose to strigose, hoary-fulvous to 

 latericeous-f ulvous ; margin thick, pallid, undulate to very 

 uneven; context white, fibrous, membranous, less than I mm. 

 thick; tubes slender, white, very variable in size and shape, 

 2-8 mm. long, mouths circular to angular or irregular, pure- 

 white, becoming pale-yellowish-brown at times on drying, about 

 3 to a mm., edges rather thick, firm, entire, becoming thinner 

 and dentate; spores oblong, 6-8 X 2.5-3 M- 



Rather common throughout on dead coniferous and deciduous 

 wood.
