HEXAGONA DYBOWSKI (Fig. 285). Pileus thin, flexible, of a 

 pale color. Surface rugulose, zoned with a dense coat of pale, slender 

 hairs, which are detersive, and old specimens evidently become almost 

 smooth. Pores medium, pale, with angular walls disposed to become 

 somewhat irpicoid. 



There are three collections of this plant from the Congo, Africa, in the 

 Museum at Paris, but it has never reached any other museum. It is a unique 

 species, very different from all others of this section in its pale context color 

 and the general color of the plant. Its affinities are rather with Trametes or 

 Polystictus .than with Hexagona.

 from which species it seems to me to be quite d
