FUSCUS. CONTEXT BROWN. 



FOMES TEXAN US. This is intermediate between Fomes igniarius and 

 Fomes pomaceus. It occurs on Juniper in the Southwest. The black, rimose surface 

 and general appearance of the plant is that of Fomes igniarius. The context color 

 is intermediate, perhaps close to pomaceus. The spores of all three are the same 

 (5-6, not 3-4, as described). Fomes texanus has yellow mycelium, agreeing with 

 Fomes pomaceus in this respect. 



FOMES CINCHONENSIS. This, for me, is a large tropical form of Fomes 

 pomaceus, differing, as far as I can note, in its large size, but in no essential character, 

 context, color, spores, or setae. It also has the abundant yellowish, mycelial hyphae 

 overrunning the old tissue, which is a frequent feature of Fomes pomaceus. 



Compare Fomes Robinsoniae on pag; 234. Should be entered here. 



FOMES ROBUSTUS (Fig. 589). Pileus ungulate, with a hard, 

 rimose, black crust. Context light fulvous. Rhei color would be the 

 best name for it, being the color of commercial rhubarb root. It is 

 near to yellow ochre of Ridgway. Pores minute, with pore tissues 

 cpncolorous. Spores globose, hyaline, 7-8 mic., guttulate when fresh. 

 No setae found by me. (I am informed that setae have been noted 

 in a Swedish specimen.)
