N o specimens of this Lichen in fructification had ever been
lound m Britain, till it was observed in that state near Newcastle
by Mr. Thornhill, and obligingly communicated to us,
in great perfection, by Mr. Winch. We cannot but expect
much from a place capable of producing so great a curiosity.
The plant itself occurs chiefly on the granite mountains of
Scotland and Wales, and is not common.
The root is strong and central. Frond many-lobed, often
so deeply as to seem formed of many leaves, membranous,
quite smooth all over, black beneath, somewhat lighter,
wnh an olive hue, above. Tubercles nearly sessile, convex,
black (as in all this tribe), their surface formed of angular
plaits, or of several separate rolls, or rather folds, not one
regular concentric roll.
We lament the necessity of retaining the old Linnaean name
pr this species, which indeed seems to us a very good one,
because we are sorry not to follow in every thing so great a
botanist and so worthy a man as Dr. Acharius; but we rely on
is candour for the present, and posterity must decide between
us m the end.
