CONTEXT AND PORES COLORED.
POLYPORUS INAMOENUS. This is an indurated subfomes form of Polyporus
gilvus. Sometimes it shows distinct pore layers. Polyporus gilvus takes this
form more commonly in warm countries, but we have specimens from California
and Dakota.
SPECIMENS. California, L. C. C. Krieger; South Dakota, Dr. Brenckle; Uruguay, Dr. F.
Felippone; Australia, E. Jarvis; New Caledonia, Museum Paris; Mauritius, P. Koenig; India, H.
Val. Ryan.

Polyporus Hookerii.
POLYPORUS HOOKERII (Fig. 683). Hooker made a collection in India
which is an extreme form of Polyporus scruposus, to which Berkeley referred it as a
"var." The pileus, instead of being simply tubercular, rough as in the American and
African forms, is strongly fibrillose-strigose (Fig. 683). If standing alone, it would be
a strong species, but intermediate collections connect it with the ordinary form of
Polyporus scruposus. There is also a specimen of this plant at Kew from Australia,
and we have it from Mexico.
SPECIMEN. Mexico, Dr. S. J. Bonansea.
Compare stabulorum.
POLYPORUS SPURCUS. Pileus thin, applanate, rigid, with a thin, rugulose,
glaucous crust, distinct from the context. Context cinnamon brown, hard. Pores
minute, with darker mouths, concolorous as to tissue with the context. Setae abundant,
slender. Spores hyaline, small.
Polyporus spurcus is known only from the type at Paris from Guadaloupe.
With the same context color, setae, and spores as Polyporus gilvus, it differs in having
a distinct, glaucous crust. It surely is not Polyporus licnoides as recently referred,
nor is it the same as Polyporus callimorphus as recently referred, which is licnoides.
There is a possibility that when Polyporus spurcus is better known it will be found to
be a Fomes.
POLYPORUS ILLICICOLA. Named from Japan, is a thin, soft form of
Polyporus gilvus, which when young is a bright, yellow color that it loses with age.
It was named and misdescribed by Hennings as having spores 8-10 x 13-16. They
are 3 x 3>. We have also the same form from Japan.
SPECIMENS. Japan, Dr. A. Yasuda.
POLYPORUS MARCUCCIANUS. Pileus applanate, with soft, brown surface.
Context dry, soft, light, floccose. Pores small, round. Setae slender,
numerous. Spores globose, hyaline, 4-4X mic.
