2. CORIOLUS ECTYPUS (Berk. & Curt.) Pat. 



Pileus tough, rigid or slightly flexible, imbricate, sessile or 

 umbonate-sessile, dimidiate, conchate, 3-7 X 4-8 X 0.5-0.7 cm.; 

 surface finely tomentose to nearly glabrous, smooth, pale- 

 isabelline with pale-rufous zones; margin thin, entire, sterile; 

 context punky, zonate, 2-4 mm. thick; tubes 2-3 mm. long, 

 white within, mouths circular to slightly angular, very regular, 

 4-5 to a mm., edges thick, entire, pallid, becoming thin, slightly 

 dentate, glistening and pale-avellaneous at maturity; spores 

 ellipsoid, 3X2/1. 



Frequent on dead deciduous wood from South Carolina to 

 Florida and Louisiana. 



3. CORIOLUS ALABAMENSIS Murrill 



Pileus thin, densely imbricate, rigid when dry, dimidiate, 

 convex above, concave below, 2 X 3-4 X 0.1-0.2 cm.; surface 

 hirtose-tomentose, isabelline, opaque, with 1-3 concentric, 

 nearly glabrous, avellaneous to fuliginous, depressed zones 

 near the margin, which is thin, sterile, pallid, somewhat plicate, 

 and entire to undulate; context thin, white, fibrous; tubes 

 punctiform, less than I mm. long, white to pallid within, mouths 

 angular, rather irregular, 3-5 to a mm., edges thin, entire, white 

 to avellaneous, sometimes umbrinous in dried specimens. 



Found only at Auburn, Alabama, on dead wood. 



4. CORIOLUS SECTOR (Ehrenb.) Pat. 



Pileus rather thin, flexible, flabelliform, often spuriously 

 short-stipitate, imbricate, laterally connate, 2-4 X 3-6 X o.i- 

 0.2 cm. ; surface multizonate, finely radiate-striate, often plicate, 

 silky, usually shining, more or less tomentose near the base, 

 avellaneous to isabelline; margin entire to fimbriate or deeply 

 dissected, sometimes palmate; context thin, coriaceous, avel- 

 laneous, about 0.5 mm. thick; tubes 0.5-1 mm. long, avellaneous 

 within, mouths angular, irregular, very variable in size, 2-6 

 to a mm., edges thin, dentate to lanceolate, avellaneous to fulig- 

 inous; spores globose, 3.5-5 M- 



Common on dead wood from South Carolina southward. 



5. CORIOLUS HEXAGONIFORMIS Murrill 



Pileus resupinate, effused, narrowly reflexed, white through- 

 out, slightly stramineous in dried specimens, 0-0.3 X 2-4 

 X 0.1-0.2 cm.; surface soft, nearly glabrous, azonate; margin
