W e resign with regret Hudson’s name for this pretty Lichen,
out of deference to Linnaeus and Acharius, see last page; but
we presume to change the word lacerus for the more classical
lacer. We gathered our specimens long ago, full of shields,
in Scotland and Westmoreland. The frouds grow nearly erect,
among moss to which they adhere, being extremely thin and
delicate, almost pellucid, light brown with a tinge of blue
sometimes very vivid, and but little changed by drying. From
a slender pale base they dilate and .divaricate into a variously
lobed and singularly jagged figure, the edges toothed or
fringed. The shields, chiefly found in the north, are when
present abundant, minute, prominent, with a red concave disk,
and thick smooth light-brown border. The young ones resemble
little grains like millet, scattered over the surface of the
fronds. Jacq. Coll. v. 3. t. 11. f . 1, surely cannot be our
plant, for nothing can be less like i t !
