Grows in dense tufts. Stems about one inch long, reclining, moderately 
broad, compressed, solid, smooth, divided into a few horn-shaped branches, 
when fresh brown oliv v e, when dry blackish; stiff, tough, horny, pellucid 
when moist. Tubercles terminating, plano-convex, circular or oblong, of 
different sizes, blackish brown, fleshy, fungous and white within. In 
some plants saucers are produced at the ends of the branches, flat or 
gently concave, border regular, of the same colour with the saucer, some¬ 
times bearing horn-shaped branches. These saucers being smaller than 
the tubercles are probably changed into tubercles. Dill.

* (From this plant is prepared the deep red dye so called ; used both by the ancients 
and moderns ; and obtained in quantity from the Canary Islands, and the Archipelago, 
whence it is exported as a valuable commodity. When scarce it has been sold for 
100(P. per ton. Mr. Gray describes the purple tint yielded by this Lichen as perish¬ 
able, but used to give a fine bloom to other colours. E.)
