Dry stony places on the more elevated mountains of the north
of Scotland, particularly abundant on the Cairngorm range, Borrer and
Hook.— This very distinct species, of which the fructification has never
been found in Britain, creeps loosely over stones and tufts of Azalea
procumbens and the alpine Trichostoma, fixing itself to them by the ends
of some of its branches.
33. Cornicularia. Ach. Cornicularia.
Thallus cartilaginous, branched, within nearly solid and cot-
tony. Apothecia orbicular, terminal, obliquely peltate, entirely
formed of the substance of the thallus, at length convex, more
or less bordered and often toothed.—Name ; comicula, little
horns, which its forked branches resemble.
1. C. tristis, Ach. (dark radiated Comicularia); thallus fruticulose
tufted deep pitchy-brown branched, the branches compressed
roughish fastigiate and somewhat distichous, apothecia
large deep-brown flattish with an entire or radiated border.

On the ground in barren heaths and on dry moors, especially in mountainous
countries.—The plant is very variable in size and ramification,
and Acharius has enumerated 5 varieties, referring the English Botany
figure, which is very characteristic of the common fructified state of the
plant, to his var. (h.

erect rigid black much branched tvith numerous capillary compound
attenuated very slender smooth patent wavy branches
pale brown at the extremities. Ach. Syn. p. 301. Lichen bice*

Upon dry rocks among mosses, on the higher mountains of Scotland,
not unfrequent ; but always barren, as it is likewise upon the Continent.
—The plant resembles coarse horse-hair as it grows scattered among
mosses.
4. C. ochroleuca, Ach. (sulphur-coloured Cornicularia); thallus
densely tufted sulphur-yellow repeatedly branched somewhat
pitted and bearing powdery warts, branches divaricated the ul-
