FUSCUS. CONTEXT BROWN. 



Richardson. It was from British America, unless Klotzsch made a mistake, for he 

 labeled it "No. 4, Richardson," and all Richardson's collections are from British 

 America. I believe Klotzsch did make a mistake, and that this is a tropical species, 

 just as I am sure that he made a mistake in publishing Irpex flavus as being from 

 "Amer. Borealis Dr. Richardson." Irpex flavus is surely a tropical species only, 

 and I believe this is. Berkeley afterwards referred quite different species from Cuba 

 and Brazil to Fomes rhabarbarinus. (Cfr. Fomes pseudosenex.) 



FOMES SANFORDII. Pileus thin, applanate, with acute 

 edge (about 1x3x3 cm.). Surface reddish brown, sulcate, with a 

 hard, tomentum, separated from the context by a narrow black line. 

 Context orange brown (Sanford brown), hard, about 2 mm. thick. 

 Pores minute, darker than context, with concolorous mouths. Setae 

 with strongly inflated bases. Spores subglobose, 3>^ mic., colored. 



We receive this from T. Fetch, Ceylon. It has some characters 

 in common with Fomes ribis, but differs from all species in this section 

 in its distinct orange brown context. 



SPECIMEN. T. Fetch, 3446, Ceylon, type. 



FOMES RHAPONTICUS. Pileus applanate (3-5 inches by 

 1-2 inches thick), with smooth, brownish surface. Context bright 

 yellow brown (yellow ochre), with a peculiar, shiny effect and faintly 

 zonate. Pores subconcolorous, minute, the indistinct layers 5-6 mm. 

 thick. Setae rare, acute, with swollen bases. Spores subglobose, 

 8-10 mic., smooth, colored. 



The context is not hard and lignescent as in most Fomes, and I 

 rather suspect it is better classed as a lignescent Polyporus, related to 

 Polyporus dryadeus. The distinct pore layers, however, can be dis- 

 tinguished, and hence it must be classed as Fomes, until at least we 

 learn more of its life history. In general appearance, context color, 

 and texture this is close to Polyporus dryadeus, an annual species of 

 Europe with white spores. 



SPECIMENS. Jintaro Umemura, Mikawa, Japan (Type), G. Yatnada, Japan. The speci- 

 men from Yamacla has no annual layers, and would be'called Polyporus. It has also darker context 

 and surface than the type. 



B. Context Dark Brown. 



FOMES EVERHARTI I. Pileus ungulate, with a black, sulcate, 

 often rimose surface. Context hard, color dark, reddish brown (burnt 

 sienna). Pores minute, in very distinct annual layers, 5-6 mm. thick. 

 Pore tissue and mouths concolorous. Setae abundant, large, slender, 

 30-45 mic. Spores globose, deeply colored, 5-6 mic. 



This is a frequent species, usually on oak in the United States. 

 It occurs from the Atlantic coast into Southwest Texas and is quite 

 abundant in the Southwest. The colored spores and setae readily 

 distinguish it from all our other American species. It is only known 

 from America, and I have never noted any specimens from tropical 

 America. Ellis sent it to Cooke, who called it Fomes igniarius. In
