CONTEXT AND PORES COLORED.
endocrocinus. The yellow coloring matter is not soluble in water,
but readily so in a potash solution. This must be an unusual species
in our Western States. It has never reached us, nor is it found at
New York.

Polyporus substygius.
POLYPORUS SUBSTYGIUS (Fig. 698). Pileus thin, rigid,
2-3 mm. thick. Surface smooth, brown, with narrow, raised, hard,
concentric zones. Context brown, thin. Pores minute, hard, concolorous,
1-1^2 mm. long. Setae abundant, with slightly thickened base.
Spores (?) globose, 3-4 mic., pale colored.
The above notes are made from type at Kew, a single specimen
from Ceylon. Others of Cooke's naming, from Malay, appear to us
to be the same, though the pileus is evidently velvety. We have also
same plant from Philippines (referred to Polyporus gilvus originally).
In Samoa our collections are also distinctly velvety, and part of the
collection we should have referred to Polystictus tabacinus. Polyporus
substygius is quite close to Polystictus tabacinus, and we are not sure
they are distinct. Substygius is not flaccid, but hard and rigid; but
for all that is probably better classed as a Polystictus (compare also
Polyporus spadiceus in Section 99). Polystictus tabacinus is supposed
to have hyaline spores, and we are not sure but that Polyporus substygius
also has.
SPECIMENS. Abundantly from Samoa, which seem to run into tabacinus.
B. Surface smooth, or at length smooth.
POLYPORUS PLORANS. Pileus sessile, dimidiate, large,
10-50 cm. Surface velutinate, at length smooth. Context reddish
brown, light, friable. Pores medium, ^-1 mm., very long, 3-6 cm.,
