l6o MARTINDALE : LICHENS OF WESTMORLAND. 



Var. picta (Tayl, Flora Hib., ii, p. 130) :- pyrithroma 



Leight., op. cit., p. 212. 



On clay slate near Staveley, rather common. My plant, 

 specimens of which have been seen and determined by 

 Dr. Nylander, must, I suppose, be regarded as a state only 

 of Taylor':; lichen. In general appearance it agrees with 

 Taylor's description, but when closely examined with a lens 

 there are several discrepancies. In particular, the bright 

 yellow pruina of the apothecia is entirely absent, and the 

 margin is not such as he describes. 



189. Lecanora luteoalba (Turner in Trans. Linn. Soc, vii, 



p. 92, fide Stizb., Lich. Helv., p. 99). Lamy, Cat., p. 62. 



On elm in Levens Park. The only Westmorland specimens 

 in my herbarium at the present time were gathered on a fine 

 elm at the entrance to Levens Park, which has since been cut 

 down. This tree was, for a large extent, almost completely 

 covered with the lichen in very fine condition. 



190. Lecanora vitellinula Nyl, Lapp. Or., p. 127; Flora, 1863, 



p. 305. Lecanora aurantiaca v. inalpma Leighton, Lich. 

 Flora, 3rd ed., p. 207, at least pro parte. 



On limestone rocks and walls. Very abundant to the south 

 of Kendal. The walls near Beathwaite Green and Levens 

 are covered with a thin badly developed form in thin 

 ochraceous patches, some of them of large extent. At Haver- 

 brack the plant is better developed with larger apothecia. 

 Near Arnside a very handsome form of it occurs with a pale 

 whitish-yellow continuous thallus, sometimes almost evanes- 

 cent, and pleasant yellow apothecia not so crowded as in the 

 other forms. In this state it comes near to saxicolous forms 

 of L. pyracea. 



191. Lecanora phlogina (Ach., Meth., p. 180 ; Syn., p. 176, sub 



L. xanthostigma) ; Nyl., Scand., p. 141 ; Leighton, Lich. 

 Flora, 3rd. ed., p. 213. 

 On trees in Levens Park. Only once gathered. 



192. Lecanora irrubata (Ach., Prod., p. 75 ? Lich. Un., p. 206 ; 



Syn. p. 40) ; Nyl. in Lamy Lich. Caut., pp. 45 and 46. 

 L. rupesiris v. rufescens and v. viridiflavescens Leighton, Lich. 

 Flora, 3rd ed., p. 204. 

 On limestone, probably not uncommon. In Mallerstang, 

 near CHburn and at Arnside.
