subhyaline. It might be recognized by comparison if ever found again. The rigid 

 pores and rather soft flesh are the most prominent characters. The species is closely 

 related to caliginosus. 



FOMES SURINAMENSIS. Pileus ungulate, with smooth, 

 black, sulcate crust. Context cinnamon brown, hard, uniform. 

 Pores very minute, with concolorous tissue and darker mouths. The 

 layers are indistinct and hardly distinguishable. Setae, none. Spores 

 globose, hyaline, 4 mic. 



This is known from Surinam, only the types at Leiden. It could 

 be compared to Fomes robustus, but setae are absent and context 

 color is of a darker shade. 



FOMES ROSEOCINEREUS. Pileus very hard and heavy, 

 applanate to unguliform. Surface with a rough, sulcate, brown 

 crust. Context dark brown (Sudan brown). Pores very minute, 

 hard. Setae, none. Spores globose, hyaline, 5-6 mic. 



This species approaches igniarius in its context color, and spores, 

 but is a heavier and harder species and pores are more minute. It is 

 known only in the museum at New York, from Cuba and Central 

 America. I think it is not well named. To my eye, there is nothing 

 roseus and little cinereous about it.

FOMES SCALARIS (Fig. 585). Pileus thin, applanate, with 

 a dark, dull, fuliginous, almost black, surface, no distinct crust. Sul-
