affixed according to its position on the substratum, 2-6 X 5-8 X 0.3-0.5 cm.; surface anoderm, 
distinctly tomentose, zonate, opaque, isabelline to umbrinous or cinereous; margin very

most specimens, umbrinous; tubes lamelloid from the first, avellaneous to umbrinous, 
furrows 1-1.5 mm. broad, 2-4 mm. deep, edges thin, entire to irregularly notched and 
splitting with age, especially behind: spores oblong, smooth, hyaline, 6-8 ~ 3-4 z.

Pileus thin, membranaceous, flexible, dry, dimidiate to reniform, laterally connate, 
applanate, 2-4 3-6 X 2-2.5 cm.; surface conspicuously tomentose, becoming nearly gla- 
brous behind, anoderm, densely zonate, smooth, avellaneous to fulvous; margin very thin, 
undulate or slightly lobed, broadly strigose until mature, fertile, pallid: context very thin, 
membranous, fulvous-fuliginous; tubes lamelloid from the first, avellaneous to fuliginous,

nearly plane below, 2 4-8 « 0.5-1 cm.; surface anoderm, tomentose, smooth or slightly 
tubercular, usually azonate, opaque, isabelline when fresh, becoming avellaneous to um- 
brinous and finally fuliginous behind, changing immediately to ferruginous or fulvous when 
bruised ; margin very thin, nearly entire, ochroleucous : context soft, punky, homogeneous, 
dull-umbrinous, 1-3 mm. thick; tubes annual, 24 mm. long, ochroleucous to isabelline 
within, mouths irregular, daedaleoid or radially elongate, averaging 0.5 mm. in width, 
edges uneven, isabelline to grayish-umbrinous or fulvous, the transverse walls often splitting
