or warts on their edges or sides, which constitute the essential distinction 
of this species, and which in drying become almost white. The shields 
are flat, of a very pale buff, surrounded when young with an entire border 
of the colour of the leaf.

L. fucifor/mis. Saucers white, mealy, small; foliage grey white; 
leaves nearly straight, even, rather velvety, branched; segments 
spear-shaped.

Leaves flat, thick, leather-like, rigid. Dill. 
Found by Mr. Gosselin on rocks on the coast of Guerney. 
(Sea-weed Lichen. E.) Dicks, iii. 17. and at King Arthur's Castle at 
Tintagel, Cornwall, by Dawson Turner, Esq. (Mr. Forster subsequently 
searched the same spot, and found nothing but L. roccella; hence Mr. 
Turner infers that these two plants are only varieties of each other, and 
that our L. farinaceus is not the real Indian one, figured in Dillenius.

L. pinas'tri. Leaves yellow green, ascending, lobed, edged with a 
yellow curled and powdery border. 
Hoffm. Licit. 7. 1. and Enum. 22. 2 — (i?. Bot. 2111. E.) 
Grows in small roundish patches : leaves half an inch high, rather upwright, 
lobed, the edges swollen. Surface often sprinkled with black dots, which 
under the microscope appear like fungous tubercles. No saucers have 
hitherto been found. Hoffman. 
Golden Pine Lichen. Cetraria juniper ini, var. /3 pinastri. Achar. Hook. 
E.) On the bark of Scotch fir-trees. Dicks, iii. 18. 
L. calica'ris. Saucers pale green grey; lateral and terminating : 
foliage pale grey green, upright, strap-shaped, branched, pitted, 
convex, ending in sharp points.

Dillenius does not think this specifically different from the L. farinaceus, 
and Mr. lielhan is of the same opinion. From one to three inches high, 
or more, variously branched. Leaves (or rather stems ) convex on one side, 
hollow on the other, with shallow oblong pits on each side, smooth, 
rather shining and stiffish. Saucers small, lateral and terminating, con¬ 
cave, becoming flat, the same colour as the plant, viz. pale greenish grey. 
The tops of the branches end in hooked points, either upright or horizontal , 
which is peculiar to this species and readily distinguishes it. Dill. (Dr. 
* (It appears from the experiments of Lord Monboddo and others, that a mucilage 
which on drying becomes transparent, and possesses the properties of gum arabic, may 
be obtained from this and some other species of Lichen. E.)
