BICOLORIS.
hard, with yellow pore mouths. Spores globose, 7-8 mic., light brown
color, smooth, punctate.
This wr as received from C. B. Ussher, Straits Settlement, and
named in Letter No. 33. It impressed me as being very curious with
its contrast of context colors and its yellow pore mouths. The pores
are not stratified, and, strictly speaking, it is probably better classed
as Polyporus than Fomes. The hard, woody nature is quite different,
however, from any other Polyporus, and suggests only Fomes.
FOMES SCULPTURATUS. As to its macroscopic features, it
is the same as Fomes mirabilis, excepting that the pore mouths are
concolorous (not yellow). The spores, however, are quite different.
Large, 14 x 20 mic., ovate, brown, with a minutely punctate epispore.
The epispore with brown marking
is thicker near the base of the
spores, and in its spores it approximates the stipitate section Amaurodermiis.
We get this plant abundantly from Henri Perrier de la Bathie,
Madagascar, and when we received it were impressed with the large,
brown spores that ally it to Amaurodermus. There is no other plant
that approximates it excepting the preceding. We thought these
spores were conidial, and we believe now that Fomes sculpturatus
may be a conidial form of Fomes mirabilis. It is curious, however,
that among several specimens received at different times from Madagascar
none have the same spores as the Malay specimen.
5TH GENERAL DIVISION, FUNALIS.
SECTION 68.
Pileus with a thick pad of dense, brown hairs, analagous to section Funalis in
Polystictus.
FOMES PSILA (Fig. 582). Pileus applanate, with thin edge,
surface covered with a thick pad of dense brown hairs. Context dark
brown (Buckthorn brown). Pores
hard, woody, very minute, with concolorous
tissue and mouths, in distinct
layers 4 to 5 mm. thick. Setae,
none. Spores not found, but surely
hyaline.
This plant is an anomalous
Fomes, and were it not for the distinct
pore layers would be classed in
Trametes by the side of Trametes Fig. 582.
hydnoides. The first wr
suggestion as that it was a lapsus of Trametes
hydnoides. It could be made the type of a monotypic genus. No
other plant is known with stratified pores and similar pileus covering.
But one specimen is known, which was sent to me from Brazil by
Rev. Rick.
