MARTINDALE : LICHENS OF WESTMORLAND. 



the short piece of Westmorland coast, it is rather remarkable 

 that it should be found inland. Perhaps the coast rocks 

 being of limestone may have something to do with its absence 

 there. Although especially a dweller by the sea, it has been 

 gathered at great distances from the coast, as, for instance, 

 among the Cevennes in France and the Himalayas in India 

 (vide Nyl., I.e.). 



146. Physcia stellaris (L., Sp. Plant, No. 27); Nyl, Syn., i. 



p. 424, p. pte. ; Leighton, Lich. Flora, p. 140, p. pte. 



On trees. Kentmere, Troutbeck. The type is somewhat 

 uncommon, but the var. leptalea (Ach., Meth., p. 198) is 

 widely distributed on rocks and stones. 



147. "Physcia tenella (Scop.); Nyl., Syn., i, p. 426; Leighton, 



Lich. Flora, p. 141 (both as var. of Ph. stellar is). 



On trees and stones. Generally distributed and abundant. 



148. Physcia aipoHa (Ach., Prod., p. 112); Stizb., Lich. Helv., 



p. 73 ; Physcia stellaris, p. pte., Nyl., Syn., i, p. 424. 



On trees. Lowther Park and Levens Park. 



149- Physcia tribacia (x\ch., L. U., p. 415; Syn., p. 191); 

 Nyl., Syn., i, p. 425, as a form of stellaris ; Ph. erosa (Borr.) 

 Leighton, Lich. Flora, p. 139. 

 On mossy walls. Common. 



Mr. Crombie, in his Index Lichenum Britannicorum, 

 Grevillea, vol. xv, p. 78, keeps Ph. erosa (Borr.) distinct from 

 Ph. tribacia (Ach.); but according to Dr. Nylander (in litt.) 

 there is no difference between them. 



150. Physcia caesitia Nyl. in Norrlin, Lapp., 326. 



On walls at Staveley, abundantly. Probably common. 



These plants have a somewhat different appearance from 

 specimens of Ph. ccEsiiia kindly communicated by Dr. Arnold, 

 of Munich, the lacinise of the Staveley plants being con- 

 siderably narrower ; but they are identical Avith specimens from 

 New Galloway, gathered by Mr. McAndrew, and which were 

 named by Dr. Nylander. The reaction with K. is the same 

 • in all. 



151. Physcia csesia (Hffm., En., p. 65, tab. xu, fig. i) ; Nyl., 



Syn., i, p. 426; Leighton, Lich. Flora, p. 141, as var. of 

 Ph. stellaris. 



On stone walls, here and there. Not very common. In 

 several places near Staveley.
