On rotten basalt at Bamborough ; on sandstone at "Whitsunbank hill, and on

 confluens, ib. ii. 175. On mountain and exposed rocks, and stone-walls, com- 

 mon. The vars., PLATYCAKPA, ^c7i. ,• and confluens, Web. are common on 

 the higher moors. 



S. OCHKOMELA, AcJi. N. On Cheviot and Hedgehope. B. On walls on the 

 Dreedreigh or Warlaw bank. This appears to have been the L. silacea of 

 "VVinch. The Rev. J. Harriman's Teesdale plant is very distinct from this, — 

 L. flavocarulesccns, Ach. 



£. HYPOLEOCE. This is a state in which the L. contigua spreads from the 

 rock in diffuse greyish white patches over soil ; apothecia few, large, at first 

 concave, then plane, and finally considerably convex, the margin thick, slightly 

 flexuose or circular, opaque black, pruinose when fresh ; spermagonia as nu- 

 merous black points. I sent an example to Mr. "VV. Mudd, who was not ac- 

 quainted with it. The sporidia are oval, unilocular, and are " very large, filled 

 with granular protoplasm." {Mudd in litt.) I found it in January among rocks 

 on the banks south of Hudshead, where L. contigua is so prevalent, and again 

 in the ravine above Lumsden shore, on soil in contact with L, contigua growing 

 on the crumbling edges of slaty rocks.
