i. ABORTIPORUS DISTORTUS (Schw.) Murrill 



Pileus normally thin, plane or depressed, circular and centrally 

 stipitate when properly developed, but often aborted and very 

 irregular, varying to entirely resupinate forms, 6-13 cm. in 

 diameter, 0.3-1 cm. thick; surface conspicuously and compactly 

 tomentose, anoderm, azonate, smooth, white to alutaceous; 

 margin thin, undulate to lobed, concolorous; context soft and 

 spongy above, hard and woody below, white or isabelline, 3-5 

 mm. thick; tubes annual, decurrent, white, 1-5 mm. long, mouths 

 irregular, variable, 2-3 to a mm., edges thin, entire to dentate; 

 spores subglobose, 5-7 ju long; stipe central, unequal, very vari- 

 able, often obsolete, resembling the pileus in surface and context. 



Frequent throughout about stumps and buried wood of 

 deciduous trees. 



15. SCUTIGER Paulet 



Hymenophore simple, terrestrial, annual, mesopous, usually 

 bright-colored; surface anoderm, variously decorated; context

 smooth or rarely echinulate, hyaline.
