Though so widely distributed a Lichen, and, as Fries remarks, "omnium Lichenum copiosissima ", this species has its limits within the parallels attained by its congeners and other plants. In the south it is stunted at Cape Horn, and neither inhabits Kerguelen's Laud or the South Shetlands ; whilst, towards the Northern Pole, it was not detected in Melville Island, though attaining a much higher latitude in Spitzbergen.

Not observed in Hermite Island or the Falklands ; nor does it extend in the Arctic regions beyond the continents of Europe and America.

Hab. Hermite Island, Cape Horn, and the Falkland Islands ; local, but very abundant where it occurs.
We cannot but regard this as the abnormal state of some Cenomyce (possibly of alcicomis or encliviafolia ?); though we have never succeeded in identifying the species. It is a highly Arctic and Antarctic plant, in the northern regions advancing to the extreme limits of vegetation, in islands beyond Spitzbergen. It also has been collected on the Andes of Peru and of Colombia.

Hab. South Chili, throughout Fuegia and the Falkland Islands ; from the sea to the hill-tops, very abundant.
A very abundant plant in the higher latitudes of the Southern Hemisphere, from Monte Video on the east, Mendoza in Central Chili, Colombia on the Andes, and Juan Fernandez on the west coast of South America to Cape Horn. Its various northern limits in the Old World are the Cape colony in South Africa, Nepaul in Asia, Swan Eiver in Australia, and Norfolk Island in the Pacific. In Tasmania and New Zealand it abounds, reaching 52° S. in Campbell's Island.
