Doubtfully distinct from U. vellea and hirsuta, with which it 

 is united in the ' Lichenographia ' and ' Enumeratio.^ Of the 

 latter, L. mtirinus, Eng. Bot. t. 2486, is a form, but the exam- 

 ples figured were of foreign growth, and I am not aware that 

 either of these is known to inhabit Britain. The Lichen under 

 consideration is plentiful amongst the Alps, and grows also 

 amongst the Pyrenees and Sardinian mountains. It is not 

 likel}'" to be confounded with any other indigenous species. The 

 Lancashire examples agree best with Schper. Exsic. 138, the 

 common Alpine variety.
