Somewhat similar to G. polyphylia, but differs at once in the black 
hirsute fibrillee of the under surface. The upper is somewhat shining, 
and is occasionally sprinkled with a few small, irregular tufts of black 
fibres. The apothevia, which are very rare in this country, are finely 
gyroso-complicate, resembling, as stated in Sm. Eng. Fl, d.¢., “ the finest 
and most beautiful filagree-work.” , 
Hab. On rocks and boulders in upland and subalpine districts. — Distr. 
Somewhat local and scarce in W., N. England, and N. Wales; general

As its trivial name denotes, this is a more luxuriant state of the type, 
with the thallus more divided, the lobes often much congested, crisp at 
the margins, and much less (or scarcely) fibrillose on the under surface, 
It is not seen fertile. 
Hab, On rocks, boulders, and stone walls in mountainous districts.— 
Distr. Only in S.W. England and among the Grampians, Scotland.—
