Grey cloudy Lichen, tawny underneath. Anglis. 



On rocks frequent, both in the highlands and low- 

 lands, as in the king's park at Edinburgh., &c. 



This Lichen varies much in appearance : Fre- 

 quently it confills only of a fimple leaf, of a 

 roundifh figure, from the fize of a fhilling to 

 that of a crown-piece, fomewhat concave on the 

 upper fide, and varioufiy waved or lobcd on the 

 margin. The fubftance coriaceous ; the colour 

 on the upper fide grey or cinereous, dotted all 

 over with innumerable minute fufcous points j 

 the under fide fmooth, or flightly wrinkled, with- 

 out veins or fibres, of a tawny colour, having 

 one root in the centre, by which it grows to the 

 rocks. 



Very often the leaf is divided to the centre, and 

 the lobes lie over one another, and are elevated 

 and waved at the margins, fo that the plant 

 feems to confift of m.any leaves, and bears a 

 fancied refemblance to the cbuds lying over,ano- 

 ther.
