'TVHIS adheres to putrid wood, fometimes by one fide of the
x _ pileus, but more frequently by a ihort lateral foot-ftalk,
which gradually expands into the fubftance of the pileus. It
grows folitary, or in imbricated clufters.
The pileus circular, but deficient on the radical fide; it is
fhaped juft like a leaf of the Soldoneila alpina • the furface
covered with a buif-coloured cottony dawn; the margin blunt,
and rolled in.
The gills very numerous, thin, and narrow; divided and
fubdivided, in numerous fineand almoft imperceptible branches.
In old fpecimens, the margin fometimes becomes lobed and
galhed, and the colour changes to a duiky brown.
It is of a tough elaftie fubftance, and abides the year
round.—Grows in Woodhou[e-Wood, &c..
