pata ; and at length, as respects the ultimate ramification, with 

 C. uncialis, b. This is the general view of Floerke, Schserer, 

 and Nylander ; and in fact, too, of Fries, though he assigns the 

 lichen a different place. 



13. C. Paptttaria (Ehrh.) Hoffm.; thallus of minute, smooth, 

 finally squamaceous and lobulate granules; podetia short; 

 smooth or now granulate ; either sub-simple, and from papillae- 

 form becoming club-shaped and cylindrical - ventricose (a) or 

 much and fastigiately branched, growing in crowded clumps (b. 

 molariformis, Hoffm.), the summits dividing irregularly into gib- 

 bous branchlets ; glaucous, now a little yellowish ; apothecia 



reddish-brown. FL Clad. p. 5. FT. L. E. p. 245. Tuckerm.

White Mountains, Tuckerman. Schserer, whose acquaintance 



with this species will scarcely be questioned, has plainly testi- 

 fied to gathering specimens of it 'furnished with a minute, nar- 

 rowly lacinulate thallus' (Enum. p. 203), a description really 

 bringing to mind the thallus of C. Ravenelii (described below) 

 imperfect squamules of which may be compared with certain 

 states of the granules of the present. And the true place of the 

 lichen is also suggested by its resemblance not only to C. turgida, 

 but to C. Santensis. 



14. C. Santensis, Tuckerm. ; thallus squamulose, small, thick - 

 ish, elongated at length and laciniate, dentate-crenate ; podetia 

 thin and fragile, short, simple, turgid, and dilating, in the man- 

 ner of the last species, into proliferous-fimbriate summits ; or 

 more cylindrical and a little branched ; the epidermis passing 

 more or less into smooth granules ; glaucescent ; apothecia red- 

 dish-brown. Suppl. 1, L c.p. 427. 



b. Beaumontii-, podetia elongated ; cylindrical; very slender, 

 dichotomously much-branched, and intricate ; the summits cris- 

 tate-ramulose.
