328 LICHENACEI, [GYROPHORA. 
Differs only in the margizial cilia being coarser, larger, and usually less 
numerous and scattered. In all probability it was this form Linnzus 
had in view when he applied the trivial name of proboscideus, from the 
resemblance of the bristles (when magnified, as in Eng. Bot. lowest fig.) 
to the proboscis of the elephant beetle (wide Eng. Fl. d.¢.). The apothecia 
in our specimens are generally but sparingly present. 
Hab. On rocks and boulders in upland and subalpine mountainous 
districts.— Distr. Not very general nor common in W. and N, England, 
among the Scottish Grampians, and in E. Ireland.—B, M.: Llanberris, 
Snowdon, and Carnedd Llewelyn, Carnarvonshire; Teesdale, Durham;

Descends apparently from the precediag, from which it differs only in 
the entire or almost entire absence of marginal cilia. Occasionally, how- 
ever, one or two very short denticulate cilia are here and there visible, 
a aes when it is more polyphyllous. The thallus is at times some- 
what rugose ; the apothecia are numerous and occasionally pedicellate. 
Hab, On rocks and boulders in subalpine regions.— Distr. Sparingly in 
N. Wales, N. England, among the geottial Grampians, and in 8. W. 
Treland.—B. M.: Cader Idris, Merionethshire; Snowdon, N. Wales; 
The Cheviots, Northumberland ; Ennerdale, Cumberland. Ben Lawers, 
Perthshire ; Ben-naboord, Braemar. Brandon Mt., co. Kerry. 
Form 3. fimbriata Ach. Lich. Uniy. (1810) p. 224.—Thallus 
polyphyllous, shortly and densely black-ciliate at the margins, occa- 
sionally sparingly fibrillose beneath.—Gray, Nat. Arr. i. p. 477;

ed. 3, iv. p. 65. ‘ 
A rather elegant form, which is constantly polyphyllous, and easily 
recognized by the lobes being densely pannoso-ciliate at the margins. The 
apothecia are occasionally pedicellate, smaller than in the type, and some- 
times but slightly plicate. 3 
Hab. On rocks and boulders, chiefly quartzose, in upland and sub- 
alpine districts.—Distr. Local and rare in 8.W. and N. England, more 
common among the Scottish Grampians, especially in Braemar.—B. M.: 
Dartmoor, Devonshire; Teesdale, Durham. Ben Lawers and near 
Amulree, Perthshire; Clova, Forfarshire; above Invercauld, Morrone,
