Is found from Kirkcudbright to Shetland, but is an un- 
common species. It prefers granite districts, but occurs 
also on schistose rocks. It is found locally in quantity on 
granite in some of the hilly districts of Kirkcudbright, but 
has not been found elsewhere in the Lowlands. In the 
East Highlands it is more frequent in the Cairngorm 
Mountains than in other parts. It is stated by Mr G. West 
to be “a common species at the side of lochs over the 
whole hill district of the Loch Ness area,” the rocks being 
schistose. It is rare in Perthshire and the West Highlands, 
though occurring in some quantity on the granite of Arran 
and Ben Cruachan. Is very rare in the Inner Hebrides, 
and has not been found in the Outer Hebrides. Is very 
rare in the North Highlands, and has not been found in the 
extreme north of the mainland. It has not a particularly 
western distribution in Scotland, as it is stated to have in 
Norway, but this may be due in part to the greater 
prevalence of granite on the eastern side. It is found from 
near sea-level in the West Highlands, and from 400 to 500 
ft. alt. in the Lowlands, and ascends to 2800 ft. in the East 
Highlands. Grows in dark-green to purple spongy masses 
on submerged rocks in streams, more rarely at the side of 
Jochs. In the latter habitat it appears to be depauperate. 
Fruit has not been found in Scotland, but this may be
