F ir s t discovered in Britain by the son of Dr. Burgess in
Dumfriesshire, and by Dr. Buchannan near Stirling. Our
specimens were gathered on marine rocks near Bangor, by
Mr. D. Turner. It generally grows on the earth, among
turf or decayed mosses, in moist situations; and sometimes
clothes foliaceous Lichens, looking like their fructification;
an instance of which was shown us by the Rev. Mr. Williams
of Shropshire.
The crust consists of minute imbricated lobed leaves or
scales, of an olive brown, somewhat glaucous. The shields
are excessively crowded in some specimens, so as to become
angular; in others they are more distant and round. They
vary in size and in colour, being sometimes pale brick-coloured,
sometimes dark chesnut. Their disk is nearly flat,
surrounded by an elevated but not broad border, of the colour
and substance of the crust, crenate, but not leafy.
Mr. Griffith authorizes us to say this is the plant he took for
L. tenuissimus; see With. v. 4. 61 and 2 1 .
We cannot see why the original name pezizoides should not
have been retained, as we presume this is Weber’s plant. Dr.
Acharius indeed rather puzzles us in his Methodus Lichenum
just published, by quoting Weber and Dickson,.and yet saying
“ the synonym in Dickson ought to be excluded.’’ Now
he has no synonym but this of Weber, whose specific name
he adopts.
