328 LICHENACEI. [GYROPHORA. 



Differs only in the marginal cilia being coarser, larger, and usually less 

 numerous and scattered. In all probability it was this form Linnaeus 

 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 (vide Eng. Fl. I. c.). 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 C'arnedd Llewelyn, Carnarvonshire ; Teesdale, Durham ;

 shire. Sleive Donard, co. Wicklow.

Descends apparently from the preceding, 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, 

 especially 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 Scottish Grampians, and in S.W. 

 Ireland. 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 Aeh. Lich. TJniv. (1810) P- 224. Thallus 

 polyphyllous, shortly and densely black- ciliate at the margins, occa- 

 sionally sparingly fibrillose beneath. Gray, Nat. Arr. i. p. 477 ; 

 Cromb. Grevillea, xii. p. 74. Umbilicaria cylindrica var. fimbriata 

 Cromb. Lich. Brit. p. 40. Lichen proboscideus var. 2, With. Arr. 

 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. 



Hab. On rocks and boulders, chiefly quartzose, in uplard and sub- 

 alpine districts. Distr. Local and rare in S.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, 

 Loch Phadrig, and head of Glen Callater, Braemar, Aberdeenshire.
