PALLIDUS. CONTEXT PALE. 



FOMES RUFO-FLAVUS. Pileus small, dimidiate, thin, with a 

 dark, reddish, thin crust. Context pale yellow. Pores in layers (cfr. 

 Myc. Notes, p. 458) in old plants. Pore mouths bright yellow. 

 Cystidia large, rough, hyaline, cylindrical, 8 x 40 mic. Spores (con- 

 id'ial) small, \ l /2 x 2>^ mic. 



This little plant appears to be rare in tropical America, and but few and scanty 

 collections have reached Europe. It was named from a Cuba collection. By some 

 means it has become established in hot houses and mines in Europe, and several 

 collections have been distributed (Rabenhorst 2005, Sydow 16) under the name 

 Polyporus Braunii. Most of the specimens found in the museums are this introduced 

 plant. Ordinarily it would not be referred to Fomes, as the usual collection is an 

 annual. I am convinced on comparing (both to eye and microscope) that the intro- 

 duced European specimens are the same species as originally from Cuba. 



Compare Brownii, canaliculatus, Engelii, paradoxus. 

 Fomes hemitephrus cfr. next subsection. 



SECTION 59. CONTEXT COLOR ISABELLINE. CONTEXT HARD. 



FOMES HEMITEPHRUS. Pileus ungulate, with dull surface, 

 becoming dark in old specimens, but indistinct crust. Context hard, 

 woody, yellowish isabelline color. Pores minute, hard, with con- 

 colorous tissue. 



This species, known only from New Zealand and Australia, is 

 abundantly represented at Kew. Specimens are recorded on Fagus. 



SPECIMEN. New Zealand, P. S. Robinson. 

 (Cfr. Fomes concavus in section 61.) 



SECTION 60. CONTEXT ISABELLINE. SOFT, PUNKY. 



FOMES FLOCCOSUS. Pileus ungulate, with a dull brownish 

 surface, indistinct crust. Context very soft, light, punky, isabelline. 

 Pores harder than the context, concolorous, small, round. Spores 

 6-7 x 12-14, narrow, elliptical, smooth, guttulate. 



The type was from Africa, having been misreferred to Fomes 

 introstuppeus by Hennings. I have a collection from Ceylon, and I 

 believe it to be the same as Polyporus levissimus, which Fries de- 

 scribed from Ceylon, and which answers exactly. Excepting as to 

 spores, it reminds me much of the specimens supposed to be young 

 Fomes fraxineus found in our country. It was described as Trametes. 



SPECIMENS. Ceylon, T. Petch. 

 Compare levissimus. 



SECTION 61. CONTEXT PINKISH CINNAMON. 



There are four tropical species with context exactly same color on comparison, 

 which matches "pinkish-cinnamon" of Ridgway's scale. The first three seem to 

 me to be same plant, excepting pore sizes. 



FOMES SEMITOSTUS. Pileus thin, applanate, rigid, with 

 hard reddish brown, sulcate, smooth surface, indistinct crust. Con-
