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 becomes
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 concolorous,
hard, slightly punky.
Pores minute, round, 3-5 mm.
long, with concolorous tissue
and mouths. Setae, none.
Spores abundant, 3x5, elliptical,
very pale colored.

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
