resinous crust, same context, and the coloration both of context and crust is 

 similar There is no similar plant in the genus Hexagona, and it might well 

 be made the type of a new genus We place it in this section on account of 

 its evident Fomes relationship, though as to form it belongs ir the next and 

 as to context color it approaches the section Pallidus. 



Fig. 294. 

 Hexagona resinosa. Co-type in museum at Berlin. 



Note. Hexagona laevis was based on nondescript material from Andaman 

 Islands. There is one poor specimen at Kew and another at the British 

 Museum. I judge it belongs in this section. 



GROUP 4, APPLANATUS. 



This is an artificial group to include species that have no one prominent 

 character to throw them into other groups, and which are flat but .not too thin. 



HEXAGONA POBEGUINI (Fig. 295). Pileus applanate, with 

 concentric, sulcate zones, and minutely pubescent. I think the pubes- 

 cence wears off to a certain extent on old specimens. Context sub- 

 ligneous, harder than others of this group, ferruginous. Pores large 

 2-3 to cm., ferruginous, with rigid walls and setae. 



This seems to be a frequent plant in Africa, and several collections are at 

 Paris and Berlin. One at the Britisli Museum was named Hexagona Wel- 

 vvitschii. In fact, the plant was discovered to be a "new species" in each of
