Exsicc. Croall n. 398 ; Cromb. n. 18. 
More closely akin to A. ochroleuca than to A. sarmentosa in the 
colouration and in the type of branching, though of more straggling 
habit than the species. 
Hab. On the ground in alpine places creeping loosely over mosses, 
ete.—Distr. Local though plentiful on the higher Grampians, Scotland.

2. A. sarmentosa Ach. Lich. Univ. p. 595 (1810).—Thallus 
pendulous or decumbent, remotely branched and entangled, more 
or less impressed-lacunose, compressed at the axils, the apices 
long and attenuate, whitish straw-coloured. Apothecia small, 
lateral, the disc dark reddish-brown; spores 2 to 4 in the ascus, 
becoming brown, 15-36 p long, 14-30 » thick.—Cromb. in Journ. 
Bot. xiii. p. 140 (1875). A. ochroleuca var. sarmentosa Nyl. Syn.

The thallus of this species is long and straggling and without the 
tufted apical branches of the preceding species, from which it also 
differs in the uniformly light colour. 
Hab. Among mosses on the ground.—. M. Cairngorm, Braemar, 
Aberdeenshire. 
3. A. thrausta Ach. Lich. Univ. p. 596 (1810).—Thallus 
slender, pendulous or prostrate, subcylindrical, occasionally com- 
pressed, especially at the axils, smooth, shining, pale straw- 
coloured ; branching frequent, the branchlets slender, tapering, 
often soraliate at the tips (medulla K—). Apothecia unknown.—

& Monogr. i. p. 187. 
Of uncertain systematic position in the absence of apothecia, but 
the structure of the cortex is that of Alectoria, being composed of 
thick-walled branching hyphe parallel to the long axis of the plant. 
The algie lie in groups. 
Hab. On trees or on rocks or sandy soil in northern regions or 
high altitudes.—B. M. Bay of Nigg, Kincardineshire, the only British 
locality but now extinct.
