HEXAGONA VELUTINA (Fig. 289). The only specimen of this section 

 known from Africa has a uniform brown color with narrow zones. It also 

 has smaller pores. Otherwise it is the same as variegata. It is known from 

 a single specimen and was called velutina. Nearly the same plant (one col- 

 lection) reached Berkeley from Ceylon. He referred it to variegata. 



Note. The following species with pubescent pilei are placed in other 

 sections : Pobeguini in Applanatus ; macrotrema in Pallidus ; bipindiensis in 

 Pseudofavolus. 



GROUP 3, UNGULAFORMIS. 



(Hexagona of the "Fomes" type are few in number, but very marked species.)

 Hexagona nitida. Type at Paris. 



HEXAGONA NITIDA (Fig. 290). Pileus with a hard, smooth, 

 sulcate, polished crust. Context ferruginous, hard. Pores medium 

 (5 to cm.) deep, i*/ 2 to 2.]/ 2 cm., reaching the crust. 



This is the only Hexagona that occurs in Europe, and it is known only 

 from two stations in the extreme south. It was first found in 1829 in the 

 Pyrenees, and in Algeria in 1844. Both were on the live oak (Quercus Ilex) 

 and came to Montagne, who named the species. He gave a good figure in 

 Flora of Algeria. Then Dr. Marcucci seems to have collected it abundantly 

 in Sardinia and his specimens (Exsiccatae No. 69) are in most of the museums 

 under the name "Hexagona (Favolus) Mori Poll.," Dr. Marcucci having referred 

 it in error to an old figure of Pollini, to which it has little resemblance. After- 

 wards Baglietto, noting the mistake, naturally discovered it must be a new
