CONTEXT WHITE. 



This species is hard and heavy and the tissue is very finely grained. 

 It is tropical, frequent in West Indies and other American tropics. 

 Also occurs in Africa, Java, and the Philippines, though the eastern 

 form differs slightly from the American form. The eastern form has 

 more minute pores and harder context. Also, it takes ungulate 

 forms. I have a specimen from New Zealand over a foot in diameter, 

 and with more than 25 annual layers. At Kew is a large, ungulate 

 specimen from Madagascar, with about fifty annual pore layers. I 

 have a Madagascar collection with paler crust than usual. 



SPECIMEN'S. Xew Zealand, W. A. Scarfe (very large), R. S. Robinson (?); Mauritius, C. A. 

 O'Connor; Madagascar, Henri Perrier de la Bathie; Brazil, Rev. Rick. 

 Compare hippopus, ligneus, sulcatus. 



FOMES MARTIUS. Pileus applanate, thin, 1-1 ^ cm. thick, 

 with a hard, smooth, reddish brown or black crust. Context white, 

 slightly punky, often tinged with orange shade directly under the 

 crust. Pores very minute, hard, slightly isabelline. 



This species is similar to Fomes hornodermus, but thinner, and 

 context not so hard. The crust also varies from shades of reddish 

 brown to black, and is often zonate. It was originally from Brazil, 

 but there are a number of collections at New York (called Fomes 

 subferreus in part) from Central America and West Indies. I have a 

 collection from Australia. 



SPECIMENS. W. W. Froggatt, Australia. 



FOMES OBESUS. Pileus globose-ungulate, with mat surface, 

 and thin, indistinct crust. Context and pores white, soft, ligneous, 

 with many narrow pore layers 2 mm. wide. 



This is based on a single specimen from Pacific Islands (Apataki) 

 on a cocoanut tree. Type at Paris. I do not know if the narrow zones 

 represent pore layers or zones of the context. 



FOMES ROSEIPORUS Pileus applanate, with a thin, smooth, 

 brown crust. Context white, with a faint pinkish tint. Pores minute, 

 pale rose. 



This was named from Java. The type is not at Paris museum. 

 The above description is from a specimen at Kew recently collected 

 in Java by v. Hoehnel. 



FOMES SUBRESINOSUS (Fig. 571). Pileus applanate, with 

 a black, smooth, shiny crust. Context white, contrasting strongly 

 with the black crust. Pores minute, slightly darker than the context. 

 Spores globose, 4 mic. hyaline. 



This is a frequent species in the East, Africa, Ceylon, India, 

 Philippines, etc., and has been known for years. I found it named 

 Fomes nigro-laccatus in the museums at Berlin and Paris, which was 

 an error said to be based on determinations of Cooke. The records of 

 nigro-laccatus, Patouillard p. 103, and Bresadola, Kamerunenses, p.
