'"p^HIS plant adhered by its bafe to the root of a poplar tree,
which was in a decaying ftate.
It is convex on the upper fide, and about an inch in thicknefs
near the bafe, growing thinner to the margin ;—the convex
part near the root is of a reddiih colour, the reft of a pure
white, and appears to the eye as if it were rubbed with chalk.
A portion of the furface, when magnified,, appeared to be covered
with a ihort velvety dawn, which glittered like filver;
—when the white dawn or powder was rubbed off, the furface
was of a pale duikyfleih colour. The margin is lobed, curled,
• and undulated, in a very pleafing manner. The fubftance of
the plant, within, is of a pale duiky fleih colour, tough, and
elaftic.—One of the fpecimens before me, meafures fix inches
from fide to fide, and near four from the bafe to the fore margin
; another is little more than half that meafure.
The tubes are about two lines in length, they adhere together
by their fides, are of a tough coriaceus fubftance, and
variable in fize and figure. The pores very unequalfome
round, others oblong or angular, fome are long and waved, fome
large, others fmall; but all of equal height.
This Ipecimen grew on the root of a fallen poplar, at Copley-
Hall, near Halifax; it grew near the furface of the ground, and
furrounded, with its fubftance, the graffes and weeds that grew
in its way.
