MARTINDALE: LICHKNS OF WESTMORLAND. 150 



form ^re/iu/ana of Withering on sandstone in Lowtlier Park 

 and near Cliburn. A rather remarkable form occurs on sand- 

 stone near Tirrill, in which the apothecia as they increase in 

 size grow darker in colour, and at length become a full black 

 and immarginate, then bearing a great resemblance to some 

 Lecidea of the contigua group. 



184. Lecanora ferruginascens Nyl., Flora, 1872, p 407- 

 Pyr. Or., p. 6. 



On clay slate near Staveley ; only gathered once. 



I publish this lichen with some hesitation, as I have never 

 seen an authoritative specimen of the Pyrensean plant, and 

 I have too little of my own to send any of it away for' con- 

 firmation. It, however, seems to agree perfectly with 

 Dr. Nylander's description.
