CONTEXT AND PORES COLORED. 



POLYPORUS ANEBUS. Pileus thin, 5-8 mm., rigid, sessile, 

 imbricate. Surface hard, smooth, brownish yellow, no distinct crust. 

 Flesh pale yellow (cinnamon-buff), firm, dry, fissile. Pores minute, 

 2-3 mm. long, slightly darker than the flesh. Hyphae pale yellow. 

 Setae, none. Spores subglobose, 3-4 mic., hyaline, smooth. 



This is a frequent plant in the East and Africa, but does not 

 occur in the American tropics. The pale yellow flesh becomes darker 

 in the old museum specimens. The following three are forms of this 

 plant, all similar as to context, pores, etc., but differ a little as to 

 surface. 



SPECIMENS. Madagascar, Henri Perrier de la Bathie; Japan, J. Umemura; Philippines, 

 E. D. Merrill. 



Compare guadalupensis, Marianus, serpens, subpruinatus.

Polyporus bicolor. 



POLYPORUS BICOLOR (Fig. 676). This is the same as anebus except that 

 the pileus develops a reddish stain; and in some collections the surface is entirely 

 dark reddish. Some collections are partly stained and partly not. We think it is only 

 a form of Polyporus anebus, or perhaps a condition. 



Compare oblinitus, sanguinarius, subpictilis, subrubidus, vulneratus. 



POLYPORUS SANGUINARIUS. In the original sense this is a synonym for 

 bicolor, but we use it for convenience for a color form when the pileus is entirely and 

 distinctly and uniformly reddish in color. It is rare in the Philippines, and from 

 there only as far as we know. The surface color is not a stain as it is in bicolor, but 

 the natural color. The context and other features are same as in anebus, bicolor, 

 and pruinatus. 



SPECIMENS. Philippines, E. D. Merrill, sent labeled "Polystictus sanguineus. Linn," as 

 labels are liable to be confused.
