 comparatively thin, 5-10 X 10-20 X 0.5-1.5 cm.; surface pellic- 

 ulose, finely tomentose to glabrous, slightly concentrically zoned 

 or furrowed, white to isabelline, latericeous or bay behind or in 

 blotches, or rarely over the whole surface; margin thin, obtuse,

4. TRAMETES SUBMURINA Murrill 



Pileus broadly effused, reflexed, imbricate, dimidiate, laterally 

 connate, 1-2.5 X 3-5 X 0.5-1.5 cm.; surface rough, finely
