Sticta crocata. Ach. Meth. 277.
FO U N D first by Mr. Dickson on the Highland rocks of
Scotland. Mr. Borrer and Mr. Hooker gathered the specimen
in our plate on trees at Inverary,
The fronds spread in a loosely imbricated manner, forming
roundish patches, and are rather leathery, siuuated, with
rounded notched lobes. The upper surface is of a dull glaucous
or greenish brown, full of numerous little smooth
hollows, separated from each other by a rude network of elevated
veins, which are rough and scurfy, producing a fine
lemon-coloured powder. The under side is of a reddish
_ brown, downy, with littje smooth lemon-coloured pits inter-
’ spersed. We have never been so fortunate as to see shields,
either in the Linnaean or any other specimens; but they
are described as of a brownish black, with a margin like the
substance of the frond. No doubt, they are much like those
of L.fuliginosus, t. 1103.— -W ith this was originally confounded
the Sticta aurata, Ach. Meth. 2 7 7, which, on our
representation, the learned author has distinguished from it,
and which is figured byDillenius and Hoffman. Finding this
last in Mr. Hudson’s British herbarium, we have suspected he
might have gathered it in Devonshire; which merits further
inquiry.
