Well marked by the densely fimbriate margins of the lobes. The 
fibrils are irregularly branched and vary in length and colour. The 
lobes arise by branching outgrowths from the main frond or fronds, 
and become crowded and overlapping. Apothecia and spermogones 
are numerous. 
Hab. On rocks and boulders from upland to alpine regions.— 
Distr. Rather rare in the hilly or mountainous regions of W. England, 
Wales and Ireland, more abundant in Scotland.—B. M. Dartmoor,

Though generally the lobes are almost naked, a few fibrils some- 
what similar to those of the species are always present. The thallus 
is probably affected by some growth conditions. 
Hab. On rocks and boulders in subalpine regions.—Distr. Rare 
in the mountainous districts of the British Islés.—B. M. Cader Idris, 
Merioneth; Ben Lawers, Perthshire; Ben-naboord, Braemar, Aber- 
deenshire; Brandon Mt., Kerry. 
Form exasperata Mudd Man. p. 119 (1861).—Thallus poly- 
phyllous, the lobes crowded, complicate, often small, ascending 
and crisp, somewhat rugose-uneven on the upper surface, smooth 
below, the fibrils sparingly produced on the margins or lower 
surface.—Var. tornata Th. Fr. Lich. Scand. p. 157 (1871): 
Cromb. Monogr. i. p. 329. G. tornata Ach. Lich. Univ. p. 222,

Eesiec. Johns. n. 94. 
Not nulike the previous form but differing from it in the generally 
smaller lobes and in the more or less uneven surface.
