C loM M U N IC A T E D by Mr. Oliver and Mr. Harriman
from Durham. We have gathered it on mofiy trees about
Amblefide, Weftmoreland. It has been noticed by but few
botanifts, being dried up and ftmmk to nothing in dry weather,
fo as to have no appearance of a vegetating fubftance;
but during rain it becomes plump and eonfpicuous. It belongs
to the obfeure tribe of gelatinous Lichens, the Collemata
of recent writers, but is one of the bed defined of that tribe,
though the accounts of authors refpefting it are by no means
clear. The following, affifted by the annexed plate, will prevent
miftakes about it in future.
The fronds grow in denfe clufters, and are from a quarter
of an inch to nearly an inch high, very gelatinous, of a dull
greenifh black, paler at the bafe. They are comprefied and
narrow at that part, much dilated upwards, longitudinally
plaited, terminated by great numbers of upright marginal turbinated
fhields, each ftanding on a thick fhort ftalk, of the
fubftance of the leaf, which forms the thick wavy border.
The difk is flattifh, of a red brown when arrived at maturity.
