W e see no reason to doubt this being the L . palmatus of
Hudson, notwithstanding the suppositions to the contrary in
Acharius and Withering; neither is his description of the
shields, which no person before him had detected, inaccurate.
Mr. Turner favoured us with specimens in fructification from
sandy ground to the north of Yarmouth, near the sea.
This species belongs to the tribe of Collemata, but is not
very gelatinous, being so thin as to be almost membranous.
Its colour is a greenish pellucid brown, often tinged with a
glaucous or purplish hue. The fronds form tufts on the ground
among moss or other Lichens, and are near an inch high,
crowded or imbricated, very much cut, forked and toothed,
the edges all revolute. Small sessile globose brown shields
are scattered about the disk of the lobes on the fore side,
whose margins are reddish and entire.
