FUSCUS. CONTEXT BROWN.
Richardson. It was from British America, unless Klotzsch made a mistake, for he
labeled it "No. 4, Richardson," and all Richardson's collections are from British
America. I believe Klotzsch did make a mistake, and that this is a tropical species,
just as I am sure that he made a mistake in publishing Irpex flavus as being from
"Amer. Borealis Dr. Richardson." Irpex flavus is surely a tropical species only,
and I believe this is. Berkeley afterwards referred quite different species from Cuba
and Brazil to Fomes rhabarbarinus. (Cfr. Fomes pseudosenex.)
FOMES SANFORDII. Pileus thin, applanate, with acute
edge (about 1x3x3 cm.). Surface reddish brown, sulcate, with a
hard, tomentum, separated from the context by a narrow black line.
Context orange brown (Sanford brown), hard, about 2 mm. thick.
Pores minute, darker than context, with concolorous mouths. Setae
with strongly inflated bases. Spores subglobose, 3>^ mic., colored.
We receive this from T. Fetch, Ceylon. It has some characters
in common with Fomes ribis, but differs from all species in this section
in its distinct orange brown context.
SPECIMEN. T. Fetch, 3446, Ceylon, type.
FOMES RHAPONTICUS. Pileus applanate (3-5 inches by
1-2 inches thick), with smooth, brownish surface. Context bright
yellow brown (yellow ochre), with a peculiar, shiny effect and faintly
zonate. Pores subconcolorous, minute, the indistinct layers 5-6 mm.
thick. Setae rare, acute, with swollen bases. Spores subglobose,
8-10 mic., smooth, colored.
The context is not hard and lignescent as in most Fomes, and I
rather suspect it is better classed as a lignescent Polyporus, related to
Polyporus dryadeus. The distinct pore layers, however, can be distinguished,
and hence it must be classed as Fomes, until at least we
learn more of its life history. In general appearance, context color,
and texture this is close to Polyporus dryadeus, an annual species of
Europe with white spores.
SPECIMENS. Jintaro Umemura, Mikawa, Japan (Type), G. Yatnada, Japan. The specimen
from Yamacla has no annual layers, and would be'called Polyporus. It has also darker context
and surface than the type.
B. Context Dark Brown.
FOMES EVERHARTI I. Pileus ungulate, with a black, sulcate,
often rimose surface. Context hard, color dark, reddish brown (burnt
sienna). Pores minute, in very distinct annual layers, 5-6 mm. thick.
Pore tissue and mouths concolorous. Setae abundant, large, slender,
30-45 mic. Spores globose, deeply colored, 5-6 mic.
This is a frequent species, usually on oak in the United States.
It occurs from the Atlantic coast into Southwest Texas and is quite
abundant in the Southwest. The colored spores and setae readily
distinguish it from all our other American species. It is only known
from America, and I have never noted any specimens from tropical
America. Ellis sent it to Cooke, who called it Fomes igniarius. In
