SPORES COLORED. SETAE PRESENT.
SECTION 72. CONTEXT BROWN (ORANGE BROWN IN ONE SPECIES).
SETAE PRESENT. SPORES COLORED.
A. Context Light Brown.
FOMES YUCATENSIS. This is similar in every particular to
Fomes rimosus, excepting that it has setae. They are thickened at
the base, and pointed. At New York there are specimens from
Central America, and at Paris I have noted a specimen from New
Caledonia (determined as Fomes rimosus), but which is characterized
in the same way. Also from Africa, where it was called Xanthrocus
rudis, it being the third time the specific name rudis was applied to
an (alleged) Fomes.
Compare rudis.
FOMES SARCITUS. Pileus applanate, rather thin, (1^ cm.,
with thin edge). Surface black, rimose, at length fibrillose, lacerate.
Context bright brown (Raw Sienna). Pores minute, with concolorous
tissue, but with darker, velutinate mouths. Hyphae deeply colored.
Setae, rare. Spores small, 3-3^ mic., globose, deeply colored.
This species from the West Indies, type preserved in a jar at
Upsala. It seems rare, at least there is no additional material in the
abundant collection from the West Indies at New York. I have a
collection from Trinidad, same on comparison as the type, but the
spores are a little larger (4-4^ mic.).
SPECIMENS. Thos. Langton, Trinidad.
FOMES OSTRICOLORIS. Pileus large, hard, woody, with
obtuse margin. Surface sulcate, black, rough. Context bright yellow
brown (ochraceous-tawny). Pores minute, with concolorous tissue
and dark purplish, velutinate mouths. Setae abundant, with swollen
bases. Spores globose, pale colored, 3>^ x 4.
This was received from Edouard Luja, Congo, Beige. In the
grosser features it is very similar to Fomes torulosus, from which it
differs in colored spores. The velutinate, dark purple pore surface is
a marked feature.
FOMES RHABARBARINUS. Pileus applanate, (5x6x1
inch), with a thick, hard, smooth, ridged, black crust. Context light
yellow brown (near ochraceous tawny), hard, woody. Pores very
minute, with concolorous tissue, but brown mouths. Setae, short,
thick, projecting 10-12. Spores not found. (The hymenial elements
are all deeply colored, and the spores are probably colored, though
it is strange they are not in evidence.)
This is known from a single specimen at Kew. When Berkeley published it
he overlooked the label (attached to the underside), and stated that it had no label
and was probably from Brazil. The label (by Klotzsch) states it was collected by
