328 LICHEXACEI. [gYROPHORA. 



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

 numerous and i-cattered. In all probability it ^vas this form Linnteus 

 had in A-iew when he applied the trivial name of prohoscideus , from the 

 resemblance of the bristles (when nia^nified. as in Eng. Bot. lowest fig.") 

 to the proboscis of the elephant beetle (vide Eng. Fl. /. c). The apothecia 

 in our specimens are generally but sparingly present. 



Hab. On rocks and boulders in upland and subalpine mountainou.s 

 districts. — Distr. Not very general nor common in W. and X. England, 

 among the Scottish Grampians, and in E. Ireland. — B. M. : Llanberris, 

 Snowdon, and Carnedd Llewelyn, Carnarvonshire; Teesdale, Durham;

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 polyphyUous. 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. ^Yales; 

 The Cheviots, Northumberland ; Ennerdale, Cumberland. Ben Lawers, 

 Perthshire ; Ben-naboord, Braemar. Brandon Mt., co. Kerry. 



Form 3. fimbriata Ach. Lich. Univ. {l^K)) p. 224.— Thallus 

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

 pionally sparingly fibrillose beneath.^ — Gray, Nat. Arr. i. p. 477 ; 

 Cromb. Grevillea, sii. p. 74. — Umhilicana cylindrica var. Jimhriaia 

 Cromb. Lich. Brit. p. 40. Lichen prohoscideus var. 2, AA'ith. 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. 



Hah. On rocks and boulders, chiefly quartzose, in upland and sub- 

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