54 THE LICHEN-FLORA 



Wales : — Barmouth. 



Channel Islands : — Jersey. Mr. Larbalestier. 



A foliaceous form ( f . foliosa, Flk = Mudd Brit. Clad. 56 !) in a dense entan- 

 gled depressed mass, occurs in Durham ! Kent ! and Leicestershire ! and 

 Hants ! and is identical with nivea, Ach. spec, in hb. Kew ! 



The smooth pale greyish-green cortex is more or less parted by irregular 

 whitish reticulations, and often becomes sub-decorticate, with adnate verrucae. 

 which sometimes are developed into scales or leaflets. This is also the case in 

 furcata, but the different chemical reaction will always distinguish them. 



3. C. turgida, Hffm. whitish or glauco-cinerascent, basal leaflets 

 laciniiform, variously divided and crenate, more or less ascending, 

 podetia smooth, squamoso-decorticate, turgido-cylindrical, branched, 

 slightly dilated, and open at the truncate, dentato-radiate apices. 



In rocky mountain ranges, rare. 1870.

4. C. Lamarckii, (Del.) according to Nyl. in Flora 1875 p. 

 447 is represented by Coem. Clad. Belg. 91 & 93, and is distin- 

 guished by K tinging the thallus of a slight yellow which quickly 

 changes to a pale ochraceous tint and by the impervious scyphi. 

 It is said to have been found on the ground, rare, (1875.) at Appin, 

 Argyleshire, by Rev. J. M. Crombie.

5. C. cervicornis, Schffir. thallus macrophylline, ccespitose, sub- 

 erect, narrowly laciniato-mtdtifid, crenate, cartilaginous, glaucous- 

 green above, white beneath, purplish-black at the base ; podetia 

 from disk of lacinis, short, slender, smooth or subverrucose, scy- 

 phiferous ; scyphi simple and leafless, or irregularly proliferous, and 

 more or less squamose.
