PALLIDUS. CONTEXT PALE.
FOMES RUFO-FLAVUS. Pileus small, dimidiate, thin, with a
dark, reddish, thin crust. Context pale yellow. Pores in layers (cfr.
Myc. Notes, p. 458) in old plants. Pore mouths bright yellow.
Cystidia large, rough, hyaline, cylindrical, 8 x 40 mic. Spores (con-
l
id'ial) small, \ /2 x 2>^ mic.
This little plant appears to be rare in tropical America, and but few and scanty
collections have reached Europe. It was named from a Cuba collection. By some
means it has become established in hot houses and mines in Europe, and several
collections have been distributed (Rabenhorst 2005, Sydow 16) under the name
Polyporus Braunii. Most of the specimens found in the museums are this introduced
plant. Ordinarily it would not be referred to Fomes, as the usual collection is an
annual. I am convinced on comparing (both to eye and microscope) that the introduced
European specimens are the same species as originally from Cuba.
Compare Brownii, canaliculatus, Engelii, paradoxus.
Fomes hemitephrus cfr. next subsection.
SECTION 59. CONTEXT COLOR ISABELLINE. CONTEXT HARD.
FOMES HEMITEPHRUS. Pileus ungulate, with dull surface,
becoming dark in old specimens, but indistinct crust. Context hard,
woody, yellowish isabelline color. Pores minute, hard, with concolorous
tissue.
This species, known only from New Zealand and Australia, is
abundantly represented at Kew. Specimens are recorded on Fagus.
SPECIMEN. New Zealand, P. S. Robinson.
(Cfr. Fomes concavus in section 61.)
SECTION 60. CONTEXT ISABELLINE. SOFT, PUNKY.
FOMES FLOCCOSUS. Pileus ungulate, with a dull brownish
surface, indistinct crust. Context very soft, light, punky, isabelline.
Pores harder than the context, concolorous, small, round. Spores
6-7 x 12-14, narrow, elliptical, smooth, guttulate.
The type was from Africa, having been misreferred to Fomes
introstuppeus by Hennings. I have a collection from Ceylon, and I
believe it to be the same as Polyporus levissimus, which Fries described
from Ceylon, and which answers exactly. Excepting as to
spores, it reminds me much of the specimens supposed to be young
Fomes fraxineus found in our country. It was described as Trametes.
SPECIMENS. Ceylon, T. Petch.
Compare levissimus.
SECTION 61. CONTEXT PINKISH CINNAMON.
There are four tropical species with context exactly same color on comparison,
which matches "pinkish-cinnamon" of Ridgway's scale. The first three seem to
me to be same plant, excepting pore sizes.
FOMES SEMITOSTUS. Pileus thin, applanate, rigid, with
hard reddish brown, sulcate, smooth surface, indistinct crust. Con-
