Highlands of Scotland ! Mr. Borrer. 



Similar in all respects to *a/ except in its upper surface 

 having extremely prominent reticulations, rising to nearly a line 

 in height, and looking like a series of erect curled squama?. 



d. mesenteriformis, Turn. & Borr. Tliallus thickish, the upper 

 side rough with elevated reticulations, and somewhat papillose.

 Gyrophora deusta, 8. mesenteriformis, Turn. & Borr. Lich. Brit. 222 (1813). 



Highlands of Scotland ! Mr. Borrer. 



Upper surface of the thallus singularly rugose, almost papil- 

 lose. The reticulations nearly as prominent as in ' c,' and some- 

 times growing out into new leaves : substance considerably 

 thicker than in the other states. 



I must refer here a specimen ! amongst Mr, Spruce's Lichenes 

 Pyrensei collected at Lac Lehon.
