4O SOUTHERN POLYPORES 



connate, 4-6 X 5-10 X 0.5-1 cm.; surface hairy-tomentose to 

 setose-hispid, grayish-tawny to ferruginous, azonate, smooth, 

 anoderm, becoming somewhat glabrous and subzonate with age; 

 margin acute, sterile, pallid, entire; context tawny-ferruginous, 

 subzonate, 2-3 mm. thick; tubes 3-5 mm. long, brownish- 

 ferruginous within, mouths angular to irregular, 3-4 to a mm., 

 edges acute, fimbriate to lacerate, hoary to dark-fulvous; spores 

 broadly ellipsoid, smooth, deep-ferruginous, 5-7 X 4-5. 5 M. 



Frequent throughout, chiefly on oak. Near P. cuticularis of 

 Europe. 



7. INONOTUS AMPLECTENS Murrill 



Pileus hemispheric, clasping, concave beneath, 1-3 cm. in 

 diameter, 1-2 cm. thick; surface soft, velvety, dark-yellowish- 

 orange; margin at first obtuse, entire, straw-colored, becoming 

 thin, undulate or toothed, deflexed and concolorous; context 

 soft, spongy-fibrous, ferruginous; hymenium at first honey- 

 yellow, becoming umbrinous; tubes 2-4 mm. long, 2-4 to a mm., 

 larger by confluence, umbrinous within, mouths at first closed 

 by a yellowish membrane, subcircular, regular, entire, becoming 

 large, irregular, coarsely toothed and concentrically split into 

 irpiciform plates; spores ellipsoid, slightly curved, smooth, 

 melleous, i-2-guttulate, 5-6 X 2.5-3.5 M- 



Found once on living twigs of Asimina in Georgia. 



8. INONOTUS RADIATUS (Sow.) P. Karst. 



Pileus corky to woody, imbricate, confluent, sessile, umbonate 

 behind, especially when young, 3-5 X 6-9 X 0.5-1 cm.; surface 

 radiate-rugose to very uneven, minutely velvety to glabrous, 

 fulvous to ferruginous-fuscous or almost black behind; margin 

 thin, pallid, undulate to lobed; context subzonate, ferruginous 

 to dark-fulvous, 1-3 mm. thick; tubes slender, grayish-umbrinous 

 to fulvous, about 5 mm. long, mouths angular, somewhat ir- 

 regular, 3-5 to a mm., edges whitish at first, becoming dark- 

 fulvous with age, glistening, thin, fimbriate to lacerate; spores 

 ellipsoid, luteolous, 4-6 X 3-4 M- 



Occasional in the mountains of North Carolina on decayed 

 alder, birch, maple, and certain other deciduous trees. The 

 usual form found on maple is quite different from the typical 

 form on alder and birch and has been called P. glomeratus by 

 Peck. The same two forms are said to occur in Europe.
