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-

 horns, which its forked branches resemble. 



1. C. tristis, Ach. (dark radiated Comicularia); thallus fruti-

On the ground in barren heaths and on dry moors, especially in moun- 

 tainous 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. 



3. C. hicolor, Ach. (black and grey Cornicularia); thallus 

 erect rigid black much branched tvith numerous capillary com-

 pale brown at the extremities. — Ach. Syn. p. 301. — Lichen bice*

 mosses. 



4. C. ochroleuca, Ach. (sulphur-coloured Cornicularia); thallus 

 densely tufted sulphur-yellow repeatedly branched somewhat
