=Fistulina pallida= B. & Rav. (_Fistulina firma_ Pk.)--This rare and
interesting species was collected by Mrs. A. M. Hadley, near Manchester,
New Hampshire, October, 1898, and was described by Dr. Peck in the
Bulletin of the Torrey Botanical Club, =26=: 70, 1899, as _Fistulina
firma_. But two plants were then found, and these were connected at the
base. During August and September it was quite common in a small woods
near Ithaca, N. Y., and was first collected growing from the roots of a
dead oak stump, August 4 (No. 3227 C. U. herbarium), and afterward
during October. During September I collected it at Blowing Rock, N. C.,
in the Blue Ridge mountains, at an elevation of nearly 5000 feet,
growing from the roots of a dead white oak tree. It was collected during
September, 1899, by Mr. Frank Rathbun at Auburn, N. Y. It was collected
by Ravenel in the mountains of South Carolina, around a white oak stump
by Peters in Alabama, and was first described by Berkeley in 1872, in
=Grev. 1=: 71, Notices of N. A. F. No. 173. Growing from roots or wood
underneath the surface of the ground, the plant has an erect stem, the
length of the stem depending on the depth at which the root is buried,
just as in the case of _Polyporus radicatus_, which has a similar
habitat. The plants are 5--12 cm. high, the cap is 3--7 cm. broad, and
the stem 6--8 mm. in thickness.

The =pileus= is wood brown to fawn, clay color or isabelline color. It
is nearly semi-circular to reniform in outline, and the margin broadly
crenate, or sometimes lobed. The stem is attached at the concave margin,
where the cap is auriculate and has a prominent boss or elevation, and
bent at right angles with a characteristic curve. The pileus is firm,
flexible, tough and fibrous, flesh white. The surface is covered with a
fine and dense tomentum. The pileus is 5--8 mm. thick at the base,
thinning out toward the margin. The =tubes= are whitish, 2--3 mm. long
and 5--6 in the space of a millimeter. They are very slender, tubular,
the mouth somewhat enlarged, the margin of the tubes pale cream color
and minutely mealy or furfuraceous, with numerous irregular, roughened
threads. The tubes often stand somewhat separated, areas being
