Hymenophore small, annual, epixylous, sessile; surface hairy 

 or glabrous, anoderm, often zonate; context tough, brown; 

 hymenium normally lamelloid or daedaleoid, but frequently 

 poroid in some species; spores smooth, hyaline. 



Hymenium lamelloid from the first; pileus very thin, dry, flex- 

 ible, i. G. striatum. 

 Hymenium not lamelloid from the first, but often becoming so

 conchate, sessile, sometimes spuriously stipitate, imbricate, 

 laterally connate and broadly attached or umbonate-affixed
