Grows very like a shrub. Stem very short, blackish. Branches wide- 
spreading, numerous, grey green. Saucers large, terminating, concave, 
smooth, fringed. Dill. Colour bluish green, the larger branches tawny, 
large for the size of the plant; smaller branches upright, cylindrical, 
thickly set with horizontal hair-like fibres. Saucers large, terminating, 
slightly concave, pale yellowish colour, sometimes an inch in diameter; 
border fringed with long radiating fibres, which sometimes also grow out 
of the under convex greenish side. Hoffm. (Dr. Smith suspects these 
radiated disks may be abortive flowers, and that the flesh-coloured rugged 
tubercles, sometimes found on the lateral branches, are the real fruc¬ 
tification. E. Bot. E.)

Short and hair-like when young (A) ; broader when older (B) ; one to three 
inches high, compressed, segments sometimes fewer and broader (C), 
irregular, grey glaucous green, smooth, rigid. Warts on the edge of the 
branches, mealy, as is the whole plant, flat, or rising, resembling saucers. 
Dill. (Rarely found. In order to distinguish this plant from L.calicaris , 
of which it has been conceived by Dillenius, Scopoli, and others to be 
only the other sex. Dr. Smith gives the following particulars in E. Bot. 
L. farinaceus ; form spreading, much branched tufts; its segments vary 
in breadth, though generally very narrow, acute, flattish, pitted, of a pale 
glaucous grey, smooth, except for the numerous irregular powdery cracks 
* (This moss may be successfully applied to hemorrhages as an astringent styptic. 
Dr. Swediaur.—The Earl of Dundonald has discovered a method of extracting from it 
a gum, perfectly answering the purpose of the calico-printers, and other manufacturers, 
to whom the gum Senegal has hitherto been a most expensive requisite. The gum from 
the Lichen may be regularly afforded at one-fourteenth part of the war-time price of 
gum Senegal, and at one-sixth of the peace-time price. Vide Nicholson’s Journal, No, 
55. E.)
