D^edalea. Sporocarp dimidiate) sessile, cork}* or leathery ; 

 hymenium borne in labyrinthiform cavities. 



Favolus. Sporocarp tough and somewhat flesh}', dimidiate, 

 scarcely Btalked; hymenium in cavities formed by thick lamellae 

 anastomosing into a network on the under side of the pilens. 



Merulius. Sporocarp extended over the substrate, soft and 

 wax-like, fleshy or coriaceous, mostly damp or covered with 

 drop- oi' water ; hymenium in shallow, sometimes gyrose cavi- 

 ties formed by a network of ridges on the upper surface of the 

 sporocarp. 



2 c. Hymenium on spine-like, tooth-like, comb-like or po- 

 pulate outgrowths. 

 Irpex. Sporocarp extended over the substrate or more or 

 less pileate, leathery ; hymenium on pointed teeth which at the 

 base are connected by a membrane. 



Hydnum. Sporocarp various in form, either extended over 

 the substrate or dimidiate-pileate, sessile or laterally stalked, or 

 erect and umbrella-shaped, or funnel-form with central stalk, or 

 branched and fruticulose ; hymenium on spines which are subu- 

 late and crowded, but free from one another even to the base. 

 1 b. Hymenium spread over more or less of the surface of 

 the smooth or xcrinkled or at most somewhat icarty 

 sporocarp {or what ansicers to sporocaip). 

 10 a. Sporocaip either erect and more or less pileate, fun- 

 nel-shaped or fan-shaped, and the hymenium borne 

 on the under side; or the sporocarp may extend 

 over the surface like a crust when the hymenium 

 is borne on the upper or exposed surface ; or the 

 sporocarp may be absent, the hymenium arising 

 from loose mycelium. 



Thelephora. Sporocarp erect or horizontal and dimidiate, 

 stalked or sessile, leathery ; hymenium similar in texture, not 

 separated by an intermediate layer. 



Stereum. Sporocarp dimidiate, more or less pileate, mostly 

 . leathery or woody, often zoned ; hymenium on the under 

 surface, firm and leathery, separated from the rest of the sporo- 

 carp by an intermediate layer.
