Podetia rather short, from 3 to 6 cm. in height, greyish-green or 
occasionally straw- coloured, corticate-areolate and rather warted, 
repeatedly branched, usually decumbent or of straggling growth, 
ascyphous, or with scyphi when very well developed, the tapering 
branches lighter-coloured at the tips. Apothecia not seen ; sper- 
mogones blackish._—C. amaurocreea £. destricta Nyl. Lich. Scand.

Often regarded as a subspecies, or even a form of the preceding, 
but distinguished by the more slender warted entangled podetia and 
by the presence of dextrictinic acid, which gives a reddish tinge to the 
paper enclosing the lichen. According to Crombie (Monogr. i. p. 181) 
it often constitutes along with Lycopodium Selago, the scanty 
vegetation of granitic and schistose detritus. 
Hab. On bare moorlands and mountains from upland to alpine 
regions.— Distr. Rare in N. Wales, N. England and §. Scotland, 
more abundant among the Grampians.—B. M. Guisboro’ and Baysdale

Thallus crustaceous, granular, forming a crust, whitish or pale-

drical, inflated, very fragile, glabrous, simple or rarely divided, 
white or glaucous-green (K + yellowish, CaCl—). Apothecia
