SPORES HYALINE. SETAE PRESENT.
FOMES DENSUS. There occurs rarely in the United States and Europe'a
thick, heavy form of Fomes conchatus, differing only in not being thin. Fomes
conchatus is usually about a centimeter thick. This form is very rare and I have
but three collections.
SPECIMENS. United States, O. M. Oleson; France, F. Fautrey; Portugal, Moeller.
ILLUSTRATIONS. Quelet, t. 17, fig. 5, is a crude cartoon intended to represent this thick
form of Fomes conchatus. The shape is about right, but the color more resembles a carrot.
FOMES LAMAENSIS. Pileus applanate, with a smooth, hard
brown or black crust. Context bright orange yellow (close to Raw
Sienna), contrasting with the dark crust. Tissue of two kinds of
hyphae, having large, thick, darker colored setae like hyphae imbedded
in the usual type. (See fig. 600, page 261.) Pores minute,
darker than the context.
hyaline, globose, 5 mic.
Setae numerous, rather thick. Spores (?)
This is an abundant plant in the East and a number of specimens
are at Leiden, collected years ago in Java. They were referred to
Fomes igniarius. Cooke got it from Tonkin years ago and referred it
for Bresadola to Fomes marmoratus (sic.). Recently the Philippine
collectors have found it in quantity, and Mr. Murrill described it as
a "new species" twice on the same page (Fomes lamaensis and Fomes
Williamsii). A year later he referred it to Fomes endothius, to which
it has no affinity. I am not sure it is a Fomes, at least I have not
noted true Fomes forms. Nor am I sure of spores. I have never
found them. Murrill records them as hyaline ; Bresadola indicates that
they are colored. The hymenial cells are hyaline and I think also
the spores. The bright color of the context is a marked feature of
this plant to the eye, and the "structure" is also unusual under the
lens. Fomes melanodermus (in Section 76) is a very similar plant,
but has abundant colored spores.
Compare Williamsii.
FOMES RHEICOLOR. Pileus applanate, with a dark, smooth
crust. Context bright rhei yellow (brighter than yellow ochre Ridgway),
hard, woody. Pores minute, concolorous or a shade darker.
Setae rare. Spores not found.
This is based on a specimen received from Leon Castillon, Argentine.
To the eye it closely resembles Fomes lamaensis, and we
at first thought it was the same thing. However, we do not find the
two forms of context hyphae that are so characteristic of Fomes
lamaensis, of the East. Nor do we know Fomes lamaensis in the
American tropics.
B. Context Dark Brown.
FOMES IGNIARIUS. Pileus ungulate (often resupinate or
subresupinate), with a hard, black, usually rimose crust. Context
dark brown (Argus brown), hard, woody. Pores minute, with concolorous
tissue, and brown mouths. Pore layers 1-2 mic. thick. Hy-
