Highland mountains of Scotland. — I have never seen it growing ex- 

 cept upon the Cairngorm mountains, in the same situations as Alec- 

 toria ochroleuca, appearing in dense erect tufts, while the latter is pro- 

 cumbent, straggling and creeping.— The apotheciti I possess only upon 

 Norwegian specimens, gathered on Setteficld near Tarfie in Doorefield. 



5. C. landta, Ach. (black woolly Comic ala via); thallus decum- 

 bent spreading- densely tufted smooth brownish-black of innu- 

 merable slender flexuose intricate rounded ramifications, apo- 

 thecia of the same colour flat or slightly convex with a jagged 

 border. — Ach. Syn. p. 846. — Lichen lanatus, Linn. — Schrad.

Rocks, in mountainous situations in the north, more frequent on the 

 highest mountains, plentiful and bearing fruit on Ben Nevis. 



6. C. ? hderomdlla, (black Plush Coniicularia); minutely 

 shrubby densely tufted erect entangled cylindrical corymbose 

 black with palish notched tips. — Lichen heteromalku,- Sm. in

In the cracks of the hark of old Elms, in Hainault forest, Mr. Sower. 

 by. — "We can find no characters suitable to this plant in Acharius, to 

 whose Genus Cvrnicularia it undoubtedly belongs. The fronds form wide 

 dense black patches, from a quarter to half an inch thick, harsh and 

 rigid, but not brittle, when dry; soft, elastic, and spongy when wet. 

 Each is repeatedly branched, from a slender base, in a corymbose man- 

 ner, upwards, so as to make a level surface at the top. The colour is 

 a deep olive-black, rather shilling, paler here and there, especially at the 

 tips, which however are often quite black, and the whole, standing upright, 

 are entangled laterally by their branches, so as to compose BOmetMUg 

 like coarse velvet or plush. No shields are discoverable." It would 

 probably with more propriety be referred to the Flings, but I have never 



seen any specimen. 



Oils. — 'flu- Coniicularia pubescent of Acharius, [Lichen pubescent, Linn, 

 and E. Bot. t. 2318) an inhabitant otwei rock-, has all the structure of 

 Bangi* atro-virens s Lyngbye, (Sligonema, Agardh): but Sir J. K. Smith 

 has represented upon it the Bhields of a Lichen. There is, however, 

 reason to believe that these supposed fructifications arc a parasitic Fan- 



gUS, which ('apt. ( 'arinii bail has detected and described in Dr. <ire\i lie's 



Scottish Cryptogamia Flora, it. 186,) as Spharia affinis : hence the spe- 

 cies must be altogether expunged from this Order.
