SOUTHERN POLYPORES 



Including the pileate species occurring in North Carolina, 

 South Carolina, Tennessee, Arkansas, Oklahoma, Texas, Louisi- 

 ana, Mississippi, Alabama, Georgia, and the northern portion 

 of Florida. Florida is so imperfectly known mycologically 

 that collections from almost any part of the state are liable to 

 bring surprises. 



POLYPORACEAE 



Hymenophore annual or perennial; context fleshy- tough, 

 corky, or woody; hymenium poroid or lamelloid, fleshy to woody, 

 never gelatinous. 



Hymenium porose. 



Hymenophore annual. Tribe i. POLYPOREAE. 



Hymenophore perennial. 1 Tribe 2. FOMITEAE. 



Hymenium furrowed. 2 Tribe 3. DAEDALEAE. 



Tribe i. POLYPOREAE. Hymenophore variable in size and shape, fleshy-tough 

 to corky, annual, sometimes reviving; surface encrusted or anoderm, glabrous 

 or hairy, zonate or azonate; context fibrous, rarely punky, variously colored; 

 tubes cylindric, sometimes splitting into teeth, usually thin-walled; spores 

 rounded or oblong, brown or hyaline; cystidia frequently present; surface of 

 pileus never conidia-bearing; stipe often present, variously attached. 



Context white. 



Hymenophore sessile. 



Tubes hexagonal, arranged in radiating rows; context 



thin. ii. HEXAGONA. 



Tubes mostly shallow, marginal and obsolete; hy- 

 menium hydnoid or irpiciform at a very early 

 stage. i. IRPICIPORUS. 



Tubes normally poroid, sometimes irpiciform from 



the rupture of the dissepiments at maturity. 

 Context duplex, spongy above, firm below; sur- 

 face sodden and bibulous. 6. SPONGIPELLIS. 



1 Exceptions occur in Ganoderma spp., Fomitella supina, and Elfvingia lobata. 

 Porodaedalea is closely allied to the Daedaleae. 



* Cerrena shows an irpiciform hymenium at maturity, much resembling species 

 of Coriolus. Daedalea and Gloeophyllum sometimes show poroid forms that are 

 very confusing.
