SPORES COLORED. SETAE NONE. 



FOMES RHYTIPHLOEUS (Fig. 592). Pileus applanate, with 

 a hard, smooth, sulcate, pale crust. Context bright rhei. Pores 

 minute, dark colored. Setae, none. Spores globose, colored, 4-5 

 mic., smooth. 



This species, remarkable for its pale crust, bright colored con- 

 text, dark pores, is known only from one old specimen in Montagne's 

 herbarium. It came from Brazil. 



FOMES JAVANICUS. Pileus applanate, smooth (2x3x5 

 cm.), with a hard, black, rimose crust. Context bright brown (ochra- 

 ceous- tawny), hard. Pores minute, with concolorous tissue, and 

 stuffed mouths. Setae, none. Hymenial cells white. Spores (B) 

 "flavidae," 3-3 ^<x4-5. 



This was collected in Java recently, and referred to Fomes in- 

 flexibilis as a variety. I think it different from Berkeley's plant in 

 black crust, much brighter context, and also spores (if they are 

 yellow). I consider the spores of inflexibilis as hyaline. The only 

 specimen I have seen is at Kew. 



FOMES MINUTULUS (Fig. 593). This is a small plant, with 

 the same crust, context, and pores as Fomes fomentarius, and to the 

 eye appears to be a small spec- 

 imen of fomentarius. It is 

 quite different, however. The 

 fresh specimen has the pore 

 mouths white, strongly glau- 

 cous. The spores in abundance 

 are subglobose, pale colored, 

 4-5 mic. 



The plants are small 

 (about 2 cm. thick). Still it is 

 not well named, for they are 

 not really "minute," and there 

 are several Fomes more "mi- 

 nute." Henning's named the 

 plant from Africa, and it has Flg - 693 - 



been reported from Borneo. There are good, fresh specimens at Kew 

 and Paris, 



FOMES GLAUCOPORUS. Pileus applanate, large, with a 

 rough, sulcate, brown crust. Context pale brown (tawny olive), with 

 concolorous pore tissue. Pores minute ( mm.) with walls about the 

 same thickness, in distinct layers, 2-4 mm. thick. Pore mouths 

 white, glaucous when fresh, when rubbed, light brownish olive. Setae, 

 none. Spores pale colored, subglobose, 4-5 mic. 



This was quite a large specimen received from Henri Perrier de la 

 Bathie, Madagascar. It is unusual in this section because of its pale,
