Dill. Muse. 91, t. 15. f. 15.—To this also is referable Cladonia 
vestita Leight. Ann. Mag. Nat. Hist. ser. 3, xix. (1867) p. 117, 
Lich. Fl. p. 67, ed. 3, p. 62. 
From C. coceifera this differs in the longer (2-3 in.), slender, and more 
squamulose podetia, as also in the absence of any chemical reactions. 
As observed, however, by Fries fil. (Lich. Scand. p. 65), specimens from 
more arctic regions are with K (CaCl) distinctly yellowish. This is also 
occasionally the case with specimens growing at high altitudes on the 
Scottish mountains, whence C. vestita Leight., which is nothing typical, 
and differs in the diagnosis from var. vestita Ach. Lich. Univ. p. 541. 
The basal squamules or leaflets are often glaucous and occasionally some- 
what large, while the podetia are frequently brownish at the base and 
sometimes proliferous. The apothecia are usually numerous, of a fine 
scarlet colour, though occasionally, as in the other species of this section, 
becoming denigrate. 
Hab, On peaty soil among mosses in upland, but chiefly in subalpine 
and alpine districts of mountainous regions.— Distr. Local and scarce in 
W. and N. England and N. Wales; more frequent among the Scottish 
Givampians ; doubtful in E. Ireland—B. M.: Hustyn Down, Cornwall ; 
Diffwys, near Barniouth, Merionethshire; the Cheviots, Northumberland. 
Ben Cruachan, Argyleshire; Ben Lawers and Rannoch, Perthshire; near 
Loch Phadrig in Glen Callater, and Cairngorm, Braemar, Aberdeenshire ; 
Ben Nevis, Inverness-shire. 
Form 1. gracilenta Fldrke, Clad. (1828) p. 99.—Podetia elon- 
gate, slender, branched ; scyphi dilated, dentato-radiate ut the mar- 
gins, substerile—Cromb. Lich. Brit. p. 21—Cladonia coccifera 3. 
bellidiflora b. gracilenta Mudd, Brit. Clad. p. 29. Cenomyce cocco- 
cephala & gracilenta Ach. Lich. Univ. (1810) p. 542. 
Differs only in having the podetia more slender, branched (2-4 
divided), and in being substerile, with the apothecia seldom rightly 
developed. 
Hah, On the ground in subalpine moorlands.—Distr. Apparently local 
and scarce in N. England, and among the Central and N. qeottish Gram- 
piaus.—B. M.: Kilhope Law, Northumberland. Rannoch, Perthshire ; 
near ele Phadrig, Glen Callater, and on Ben-naboord, Braemar, Aber- 
deenshire. 
f. Hookeri Nyl. Syn. i. (1860) p. 221.—Podetia glabrous, 
unequally corticate, esquamulose, or occasionally here and there with 
a few small squamules. Apothecia large—Cromb. Grevillea, xi. 
p- 114.—Cladonia Hookeri Tuck. Syn. (1845) p. 55. 
Characterized by the naked or almost entirely naked podetia. In the 
only British specimen seen these are about 1 in. high, robust, entirely 
esquamulose, with the apothecia somewhat large, conglomerate, and 
having a few minute squamules intermixed. 
Hab. On the ground in subalpine mvorlands.—Distr. Very local and 
rare, having been seen only from one locality among the N, Grampians, 
Scotland.—B. M.. Glen Candlic, Braemar, Aberdeenshire.
