CRYPTOGAMIA, ALGiE. Lichen 
35 
(Brittle Globe Lichen. Acharius and Hooker consider that this plants 
their Sphcerophoroji fragile, is more properly represented by E. Bot. 2474, 
than by plate 114, L. fragilis of that work, which is their Sphoero - 
phoron compressum. E.) On rocks and stones on mountains and high 
heaths. (On Cheviot and near Harbottle : on rocks at Muggleswick, at 
Knitsley, and near Egleston, Durham. Mr. Winch. Rocks in woods near 
St. Ives in the parish of Bingley, Yorkshire; where I have frequently 
observed it in fructification, even in the driest season. Hailstone in 
Whitaker’s Craven. E.) P. Jan.—Dec. 
L. vermicula'ris. Tubercles dark brown, very small, few, lateral, 
globular; branches white, nearly cylindrical, awl-shaped, spread¬ 
ing from one central point. 
Jacq. Coll. ii. 12. 2— Hoffm. Lich. 29. i. 3— Dicks. 6. 10—( E. Bot. 2029. E.) 
In tufts. Issuing and diverging from one central point. Awl-shaped, two 
to three inches long; soft, hollow, snowy white, reclining; very rarely 
branched, sometimes here and there a little tooth is found, but no leaves. 
Jacq. Stems awl-shaped, tapering to a point, irregularly matted toge¬ 
ther, variously bending, rarely forked, here and there a short lateral 
branch, not unlike tubercles, hollow within, tough and pliable when 
moist, brittle when dry. Hoffman. 
(Vermicelli Lichen. E.) L. vcrmicellaris, and also L. suhuliformis of 
Gmel. Syst. Veg. Among moss on the higher mountains of Scotland. 
(At or near their summits: also on moors between Forfar and Cortachy.

L. rangiferi'nus. Tubercles brown; plant hoary, hollow, very much 
branched; terminating branches mostly turned downwards.

Ger. Em. 1572. 5— Park. 1310. 8— Kniph. 6. 
Branches perforated in the forks. Linn. Light, brittle, hoary when dry; 
grey green or whitish, tender and soft when fresh. Surface covered with 
mealy particles. Has neither leaf nor leafy crust. Roots not easy to 
find; it adheres slightly to the earth and to mosses, from which it readily 
separates. But many species of Lichen seem destitute of roots, and to 
be nourished by the leaves, or by a mucous matter at the base. About 
two inches high, divided and subdivided into branches all the way up, the 
ends turning down. Tubercles small, roundish, reddish, shining, black 
when dry, on the terminations of the branches. Dill. 
Var. 2. Ends of the branches reddish. 
Dill. 16. 30 —FI. Dan. 539. 
Smaller branches reddish, and the whole when old turning brown. Tubercles 
darker brown than those of the preceding, more crowded, more frequently 
found. Branches sometimes bearing small crisp leaves. Dill.

and high exposed mountainous situations. Dill.—and woods. Huds.

* (The Laplanders could not exist without this plant. With them it grows at least a 
foot high; and continues increasing in size for several years. It is the food of the rein¬ 
deer, which will grow fat upon it, and that animal supplies every necessary of life for 
the contented people of that inhospitable climate. Beneath open pine groves many miles 
of otherwise sterile surface are covered with it; and there the, rein-deer penetrate the 
deepest snow to procure it. Vid. Linn. FI. Lap. p. 332. E.)
