3O SOUTHERN POLYPORES 



Pileus thick, smooth, opaque; plant abundant in temperate 



regions. I. P. cinnabarinus. 



Pileus thin, often zonate, brilliant-red; plant abundant in 



the tropics. 2. P. sanguineus. 



i. PYCNOPORUS CINNABARINUS (Jacq.) P. Karst. 



Pileus convex-plane, dimidiate, laterally extended, reviving 

 the second season, 4-6 X 5-10 X 0.5-1 cm.; surface azonate, 

 rugulose, pruinose to tomentose, at length glabrous, the color 

 changing from light-orange to cinnabar-red, often fading with 

 age; margin acute, except in large plants, faintly zonate; context 

 floccose, elastic, zonate, reddish; tubes nearly equaling the 

 context, firm, miniatous within, the mouths small, 2-3 to a mm., 

 regular, coccineous, dissepiments rather thin, entire; spores 

 6-8 X 2-3 /x. 



Frequent in the southern Appalachians on dead wood of 

 various deciduous trees. 



2. PYCNOPORUS SANGUINEUS (L.) Murrill 



Pileus thin, coriaceous, sessile or spuriously stipitate, dimidiate, 

 conchate or reniform, imbricate, laterally connate at times, 

 3-5 X 4-8 X 0.4-0.6 cm.; surface zonate, finely tomentose to 

 glabrous, bright-red, often variegated with yellowish-red zones, 

 fading to pure-white in old specimens exposed to the sun; margin 

 acute, finely tomentose, yellowish-red; context floccose, elastic, 

 yellowish-red, 1-3 mm. thick; tubes annual, very short, bright- 

 reddish-miniatous, scarcely a mm. long, mouths circular to 

 angular, regular, minute, 3-5 to a mm., edges thin, firm, entire, 

 concolorous with the interior; spores oblong, 3-4 X 1-2 p. 



Frequent in most of the southern states, especially along the

 wood. 



1 8. AURANTIPORUS Murrill 



Hymenophore large, annual, epixylous, sessile, dimidiate; 

 surface anoderm, sodden, bibulous, reddish-orange, soon fading; 

 context reddish-yellow, fleshy-tough to woody, juicy when 

 fresh, rigid when dry, conspicuously zonate; tubes small, slender,

 X 10-40 X 1-3 cm.; surface rugose, sodden, velvety with short
