On rocks and stones in the neighbourhood of Eglestone, Durham,

2. R.fraccinca, Ach. (Ask Ramalina); thallus pendent flat 

 pitted and reticulated greenish-grey glabrous much branched 

 especially from below, the segments linear-lanceolate attenu- 

 ated often jagged, apothecia large submarginal plane or convex 

 at length rugged. — Ach. Syn. p. 296. — Lichen fraxineus, Linn. 

 —E. Bot. t. 1781.— Dill. Muse. t. 22. f. 59. 



Abundant on the trunks and especially the large branches of very old 

 trees, Oak and Ash, and bearing apothecia copiously. — Fronds often 

 .5 and 6 inches long; but variable in length and in the breadth of their 

 segments. — This has been used in Glasgow for the same purpose as 

 Kvernia prunashi, 



3. R. fastigidta, Ach. (fastiyiate Ramalina); thallus erect 

 pale-green much branched and tufted rigid compressed lacunose 

 smooth naked, the segments dilated upwards and bearing short 

 spur-like branches, apothecia subterminal nearly sessile pale flat. 

 — Ach. Syn. p. 296. — Lichen fastigiatus, Ach. Piodr. — E. Bot, 

 t. 890.— L. calicaris, Huds.—Dill. ' Muse t. 23. f. 62. 



Trunks of trees, frequent. — A variable plant, especially in its ramifi- 

 cation. 



4. R. soopulorum, Ach. (Rock Ramalina); thallus pendent 

 pale greenish- white compressed sublaeunose somewhat polished 

 branched the segments linear attenuated, apothecia scattered 

 on short stalks of the same colour as the thallus. — Ach. iSjyae,

 —Dill. Muse. t. 17./ 38. (Ark.) 



On rocks near the sea, abundant. — This appears to hold the place in 

 northern regions that Roccella iinctoria docs in the southern. I find it 

 sometimes difficult to distinguish small specimens of this from Rama On * 

 fastigiata. It is indeed, usually, much larger and pendent. I have 



gathered individuals 6 — 8 inches long, < u the 1 ' >tanding stones ofSti n-
