CONTEXT AND PORES COLORED. 



POLYPORUS SPADICEUS. Pileus thin, rigid, 2-3 mm. thick. 

 Surface smooth, brown, with narrow, raised, hard, concentric zones. 

 Context brown, thin. Pores minute. Setae, none. Spores abundant, 

 globose, 4 mic., colored. 



To the eye this is the same as Polyporus substygius, and our 

 figure 698, page 364, might represent either. The absence of setae and 

 abundant spores mark the difference. The type at Kew is a single 

 specimen from India. We have it abundantly from Africa. The 

 species is quite close to Fomes fastuosus. 



SPECIMENS. Dr. G. Zenker, Kamerun, Africa. 

 Compare Fomes halconensis. 



POLYPORUS CARYOPHYLLUS. Pileus applanate, sessile 

 (6x8x1), unicolorous, dark reddish brown (chestnut). Surface soft, 

 velvety, sometimes forms a pad 1-2 mm. thick, but disappears or be- 

 comes indurated on old specimens. Flesh hard, fibrillose, concolorous. 

 Pores minute, concolorous, 3-5 mm. long. Setae, none. Spores 

 globose, 3^-4 mic., deeply colored. 



Cooke gave the plant a good name which well expresses its color. 

 There are abundant types from Brazil at Kew. It is also found in 

 Brazil by Rev. Rick. The plant is a Polyporus, not Fomes as found 

 in Saccardo. 



SPECIMENS. Brazil, Rev. J. Rick, Rev. F. Thiessen. 



POLYPORUS PUBERTATIS (Fig. 692). Pileus sessile (3 x 

 6xl> cm.), unicolorous dark brown (Verona brown). Surface 



minutely pubescent, soft to 

 the touch. Flesh concolor- 

 ous, hard, slightly punky. 

 Pores minute, round, 3-5 mm. 

 long, with concolorous tissue 

 and mouths. Setae, none. 

 Spores abundant, 3x5, ellip- 

 tical, very pale colored. 



Based on a collection from 

 Prof. A. Yasuda, Japan (No. 

 F| fl- 692 - 38). It is unknown to us 



otherwise. 



POLYPORUS WILSON* 1 1. We know this only from our notes, in New York 

 Gardens. It came from Honduras. Context and pores bright rhei color. Shape like 

 Polyporus gilvus. Surface soft, velvety, pubescent. Setae none. Spores 3x4, pale 

 colored. It impressed us as something very distinct. It is only known from the 

 type collection. 



POLYPORUS MELAENUS Pileus thin, sessile (described 10-20 cm. broad). ' 

 Surface smooth, black. Context buckthorn brown, hard, brittle. Pores much
