M r . DICKSON first noticed this species on the trunks of
Scotch firs in the Highlands. Mr. Turner very unexpectedly
detected a few small plants of the same on Mr. Rigby’s pales
at Framingham near Norwich, the most elevated spot in
Norfolk, one of which is drawn at Jig. 1.
This is truly a beautiful as well as very rare Lichen. The
fronds spread loosely in irregular tufts, and are of a l soft
membranous texture when moist, smooth on both sides, and
of a pale glaucous brown, with a strong tinge of yellow;
but the latter hue is overpowered by the bright lemon-colour
of the copious powder, borne by the numerous rounded and
curled marginal lobes, which grow upright, though the leaf
itself is depressed. When Dr. Acharius published his Pro-
dromus he had never seen the shields. We have drawn them,
Jig. 2, from a specimen in the Linnaean herbarium, they being
no where figured. The idisk is bright chesnut; the border!
thin, somewhat notched, yellow.
Our learned friend has, in his Methodus, reduced this to a
variety of L . juniperinus, which last has never been found in
Britain. We have gathered both, with no small pleasure and
attention, in Savoy, and can hardly be persuaded to unite
them. Hoffmann’s t. 7 is sufficiently expressive of their
differences, though we own juniperinus often produces yellow
powder.
