'"pHIS Helvella. fometimes adheres by its whole underfide, to
dry wood and branches "of trees, in a ftate of decay ; fornetimes
it is detached round the fides, and the margin much elevated
M that it feems to adhere by a central bafe only.
The upper furface is foft, and fmooth to the touch, but made
uneven by riling bunches , particularly in the larger Specimens.
The plant, both in colour and fubftance, very aptly refembles
the beft Cured Spanifli tobacco, by which character, and its golden -
margin, it is at once diftinguiihed. .The figure -is in general round,
the margin elegantly lobed r'the: lobes crenated or dented, and
edged with a fine golden-coloured lace. . '
The underfide is veined and wrinkled', naked and of a colour
fomewhat paler than the upper! The plant fometimes fpreads to
a confiderable di f tanceI have feen it run upon the decayed ihoots
of common woodbine or honeyl'uckle, to the length of two or
three feet, in the manner exprefled in. the upper figure-on the
plate. It is in perfection in February, and foon periihes. It re-,
fembles the Auricularia ferrugenia, of M H 1 but I think
it a diftinit fpecies..
