LICHEN sinopicus.
Sinoper Lichen.
CRYPTOGAMIA Algce.
G en. Char. Male, scattered warts.
Female, smooth shields or tubercles, in which the
seeds are imbedded.
Spec. Char. Crust rounded, tumid, smooth, tessellated,
of a rusty red. Shields minute, sunk, black, depressed
in the centre, with an imperfect crenate
border of the substance of the crust.
Syn. Endocarpon sinopicum. Ach. Meth. Suppl. 30.
F o r this new Lichen we are obliged to Mr. Turner. That
gentleman received it from the Rev. Hugh Davies, by whom
it was gathered in Anglesea, growing on a piece of yellowish
hone schist.
Though small, it is a conspicuous as well as elegant species,
forming little rounded tumid smooth patches, a line or more
in diameter, and often associated into wider tessellated masses,
of a ru.sty red hue varying in brightness. A few strongly depressed
minute dots are situated in each portion of the crust,
becoming at length small black shields, hollow in the middle,
with a spurious sort of crenate border of the substance and
colour of the crust.
Our specimens agree with those communicated by Mr. Wah-
lenberg, the original discoverer of this species in Lapland.
The specific name alludes to a red kind of stone, called
Sinoper, which this Lichen resembles in colour.—Mr. Turner
suggests that Urceolaria diamarta of Acharius is probably no
other than this plant.
