HEXAGONAS. 



Having studied and photographed every type specimen of Hexa- 

 gona in the museums of Europe, and having written a synopsis of the 

 genus, I feel in position now to pass on the specimens of this family 

 that I receive from my correspondents. 



Mr. Edouard Luja, Congo Beige, has sent me a fine lot of Poly- 

 pores, including three species of Hexagona. One species, Hexagona 

 Henschalli, (cfr. Synopsis, page n) had reached Europe, there being 

 only a single specimen at Kew. Mr. Luja sends it abundantly. The 

 pores are large and flaccid, with a pale pore surface. A section through 

 the pore walls shows a-thick, white, exterior layer (hymenial probably) 

 quite distinct from the colored hyphae of the trama. 



HEXAGONA POBEGUINI (Fig. 387, cfr. also Synopsis, page 

 1 8, fig. 295). I thought I knew this species, having seen and photo- 

 graphed it in three different museums under three different names.

 Hexagona Pobeguini. 



but when I first saw Mr. Luja's specimens I did not recognize them. 

 The truth is, I think, that the species was named and described from 

 old specimens that have changed very much. Mr. Luja's are the first 

 good, typical specimens that have reached Europe. When the plant 

 is in good condition it is densely covered, both pileus and pores, by a 

 brown, velutinous coat that disappears largely from old specimens.
