PALLIDUS. CONTEXT PALE.
annosus in context color and surface color, but differs in its peculiar
shape, and pore development. The pores of the form contin-
species
uous layers, as is usual in Fomes, not separate and independent layers,
as in Fomes annosus. The type specimens are two to three inches
wide, but the collector states that it "grows very large."
SECTION 57. SMALL. CONTEXT WHITE OR ISABELLINE.
\Yc include in this section Fomes ohiensis, which really forms a section of
itself. It has large, obovoid, truncate, hyaline spores, similar (except color) to the
that characterize the section Ganodermus. No other known Fomes has
spores
riilar spores, but Polyporus ochroleucus does have such spores, and in a natural
arrangement should be classed in same section with Fomes ohiensis.
FOMES OHIENSIS. Pileus small, dimidiate, usually less than
2 cm. in diameter, > cm. thick, white, hard. Surface smooth, even,
with no distinct crust. Context and pores white. Pores small, round,
regular. Spores obovate, truncate at base, hyaline, smooth, 8x12-14.
This is quite a frequent little species in Ohio, growing around
Cincinnati, usually on rail fences, rarely on logs in the woods. At
New York there is a collection from Cuba, and Romell records it
from Brazil. But one collection is so referred from Europe, sent to
me from Portugal by Rev. Torrend, but I can not be sure it is not a
small specimen of Polyporus ochroleucus. It is unknown from the
East being replaced there by Polyporus ochroleucus.
SPECIMENS. A dozen from Ohio, mostly my own collections, one collection from Dakota,
Dr. J. F. Brenckle, but not elsewhere have I gotten this typical form.
Large form. There occurs in New York State a larger form than the usual
seen one collection
Ohio form. I have a specimen Ixlxl^ inches. I have only
of it from the west.
SPECIMENS. New York, L. H. Weld, D. Reddick; Ohio, Hurt Leeper.
FOMES SCUTELLATUS. Pileus ligneous, usually scutellate
from position of growth on underside of branches, rarely dimidiate,
small, usually about a cm. in diameter. Surface rugulose, dark brown
or black. Context isabelline. Pores minute, the tissue isabelline, but
mouths, when fresh, white. Spores not found by me.
This little species is American only, as far as known. It grows
usually on under side of alder, .hazel, and other soft wood branches,
lying on the ground in moist places. It is common in the swamps of
our northern and eastern States. I do not find spores even in freshlycollected
material. Fomes scutellatus is well named, for in every collection
I have, excepting one, all specimens are scutellate. It is rarely
dimidiate. Morgan confused Fomes ohiensis under the name Fomes
scutellatus.
SPECIMENS. Eight collections all from the north, Canada, Michigan, or the east, New
York, Vermont, etc.
