Somewhat similar to G. polyphylUt, but differs at once in the black 

 hirsute fibrilte of the under surface. The upper is somewbat shining, 

 and is occasionally sprinkled with a few small, irregular tufts of black 

 fibres. The apotliecia, which are very rare in this country, are finely 

 gyroso-complicate, resembling, as stated in Sm. Eng. Fl. /. c, " the finest 

 and most beautiful hlagree-work." 



Hah. On rocks and boulders in upland and subalpine districts.— iii'sir.

As its trivial name denotes, this is a more luxuriant state of the type, 

 with the thallus more divided, the lobes often much con<>ested, crisp at 

 the margins, and much less (or scarcely) fibrilluse on the under surface. 

 It is not seen fertile.
