SOUTHERN POLYPORES 41 



9. INONOTUS LUDOVICIANUS (Pat.) Murrill, comb. nov. 



Pileus applanate, undulate, radiate-rugose, cuneate and 

 substipitate behind, reaching 20 cm. long, 15 cm. broad, and 

 1.5 cm. thick; surface velvety-scrupose, soft to the touch, 

 ferruginous, margin sinuate, thin; context ferruginous, with 

 silky luster; tubes concolorous, soft, decurrent, the mouths 

 circular, minute, at first whitish-stuffed, becoming fuscous- 

 ferruginous and lacerate; spores smooth, ovoid, ferruginous, 

 6 X 3.5 At; cystidia none. 



Described as Xanthochrous ludovicianus (Bull. Soc. Myc. Fr. 

 24: 6. 1908.) from specimens collected at the base of dead trees 

 near St. Martinsville, Louisiana, by Langlois. Xanthochrous 

 fusco-velutinus Pat., described at the same time from the same 

 locality, is not specifically distinct. The species is known from 

 a few collections by Langlois in Louisiana, on dead logs and 

 branches of Quercus aquatica and probably other deciduous 

 trees, and was also found by C. L. Shear in Summerville, South 

 Carolina, occurring on the base of an oak stump. 



28. PHAEOLUS Pat. 



Hymenophore large, irregular, annual, spongy to corky, 

 epixylous; stipe simple, variously attached, wanting at times; 

 surface of pileus anoderm, hispid; context ferruginous; tubes 

 irregular, thin-walled; spores ellipsoid, smooth, hyaline; cystidia 

 none. 



i. PHAEOLUS SISTOTREMOIDES (Alb. & Schw.) Murrill 



Pileus spongy, circular, varying to dimidiate or irregular, 15- 

 20 cm. broad, 0.5-2 cm. thick; surface setose-hispid to strigose- 

 tomentose and scrupose in zones, ochraceous-ferruginous to 

 fulvous-castaneous or darker, quite uneven, somewhat sulcate, 

 obscurely zonate; margin yellow, rather thick, sterile; context 

 very soft and spongy, fragile when dry, sometimes indurate with 

 age, flavous-ferruginous to fulvous, 0.3-0.7 mm. thick; tubes 

 short, 2-5 mm. long, flavous within, mouths large, irregular, 

 averaging I mm. in diameter, edges thin, becoming lacerate, 

 ochraceous-olivaceous to fuliginous, rose-tinted when young 

 and fresh, quickly changing to dark-red when bruised; spores 

 ellipsoid, 7-8 X 3-4 At; stipe central to lateral or obsolete, very 

 irregular, tubercular or very short, resembling the pileus in surface 

 and substance. 



Common throughout on trunks, stumps, and roots of various
