SECTION 59. CONTEXT ISABELLIXE.
FOMES FUSCO-FALLENS. Pileus ungulate or applanate;
with hard, dark, rough crust. Context hard. Pores minute, round,
2-3 cm. long, tissue isabelline near the mouths, but darker fuliginous
above. Cystidia, none. Spores globose, 4-5 mic., hyaline (or seem-
ingly very pale color).
This was received from the Philippines Xos. 3693 and 11352,
named in mss. by Bresadola. It was not published in either of his
Philippine lists. The tendency of the pore tissue to become darker
is a feature of Fomes hornodermus. and the two species are related
in other respects.
SECTION 67. BICOLORIS.
FOMES GRAFFI I. Pileus applanate, sessile, (3 cm. thick)
with a hard, rugulose, brown crust. Context pale isabelline, yellowwhen
moist, hard, ligneous. Pores dark brown, minute, 1^-2 cm.
long, hard, with brown pore mouths. Spores globose, deep colored,
14 mic., smooth.
This is the third Fomes that has reached me belonging to the
peculiar section with pale context and dark pores. All three of them
in macroscopic characters^ are about the same, and to the eye alone
would be held as the same. But the spores are very different as
follows: Fomes sculpturatus, Madagascar Spores elliptical, 14 x 20,
pale colored, with sculptured surface. Fomes mirabilis Straits Settlements
Spores small, globose, 7-8 mic., pale colored. Fomes
Graffii, Philippines Spores large, 14 mic., globose, deep colored.
We have a feeling that it is a spore variation of same species, but we
can not prove it and we would not assert it.
Fomes Graffii reached me labeled "Ganoderma bataanense" Xo.
19097, province of Bataan, collected by P. W. Graff. This was
originally published as Amaurodermus, and, in my opinion, should
have been so left. It was compiled in Saccardo as Ganodermus. I
do not know Amaurodermus bataanensis excepting by description,
which differs from this specimen in almost every point, and, besides,
it is surely not a Fomes.
SECTION 69. CONTEXT BROWN.. SPORES HYALINE. SETAE ABSENT.
FOMES YASUDAI (Fig. 606). Pileus ungulate, (3-4 inches)
with smooth, uneven, annular, sulcate, light brown crust. Context
light sagal brown, scanty. Pores very minute, in annual layers 2-3
mm. thick. Pore tissue cinnamon, paler than the context. Pores
subglobose, hyaline, 3>-4 mic. Setae none.
Based on a specimen (No. 8) from A. Yasuda, Sendai, Japan.
Strongly marked by the narrow, annular, sulcate rings of the surface
caused by the overlapping annual growths. There are a few narrow
layers of context interposed between some of the pore layers, and as
these are absent between most of the pore layers, it is due no doubt
to seasonal conditions, and probably represent wet seasons. As to
