This strongly marked species is only known from Ceylon. Berkeley pub- 

 lished it in 1847 with a good figure and sent specimens to both Fries and 

 Montague. That sent to Montagne (Fig. 292) was typically sulcate, but the 

 specimen to Fries (Fig. 293) was more even. Berkeley did not retain a speci- 

 men in his own herbarium, and when some twenty years later he received the 

 smooth form also from Ceylon he described it as Hexagona durissima. It is 

 the same as the specimen of sulcata he sent Fries. Whether or not it is 

 the same species as sulcata I do not know, but I think probably only a smooth 

 form.

Hexagona durissima. 



HEXAGONA DURISSIMA (Fig. 293). This seems to be practically the 

 same plant as sulcata except it has a more even crust. It is known only from 

 Ceylon, but recently I have seen a specimen so referred, and probably cor- 

 rectly, from Java. 



HEXAGONA RESINOSA (Fig. 294). Pileus applanate, with a 

 dark resinous crust. Context hard, sub-woody, pale alutaceous or pale 

 ferruginous. Tubes medium, 5 to cm., i to i l / 2 cm. deep, pale color, 

 with rigid walls. Spores (teste Murrill) hyaline, smooth, 4x6. 



This species was recently well named by Murrill, from the Philippines, 

 and is very different from all others. It is known only from one collection 

 or record. 19 Its natural relations I think arc with Fomes pinicola, the same
