21. C. Boryi, Tuckerm. Th. (crustaceous) evanescent; podetia 

 turgid, fruticulose, dichotomous, fastigiate-ramose, rugulose becoming 

 reticulate-perforate, pale sulphureous and glaucescent ; axils scyphi- 

 form, entire, at length cribrose-perforate ; sterile apices scyphiform, 

 cristate-dentate, entire becoming cribrose, with fuscous tips ; fertile 

 ones somewhat cymose-radiate ; apoth. flesh-colored, at length dark- 

 fuscous. C uncialis, var. reticulata, Russell, in Essex Jour. Nat. Hist.

 detia incrassated, obtusish, lacunose-subperforate, glaucous ; axils and

On the earth, near the sea, fertile ; Hingham, Duxbury, Mr. Russell!

 — /5, alpine and montane districts, infertile ; White Mountains. Mo- 

 nad noc, iJwsseZZ.' Newfoundland, i?or?/ .' I have endeavoured to point 

 out the features that seem to distinguish this remarkable Lichen from 

 C. uncialis, but it is possible that the conclusion of its original indica- 

 tor may be correct. The podetia become very turgid, and at length 

 often explanate, measuring in one of my specimens eight lines in di- 

 ameter at the base, and five where the branches begin. The New- 

 foundland specimen, and our alpine ones, belong to an apparently 

 sterile, subalpine state of the Lichen. 



Series 4. Cocciferce, Fr. Podetia greenish, becoming fulves- 

 cent at the base. Apothecia scarlet. 



* Podetia cartilagineous-corticate, never finely pulverulent. 



22. C. cornucopioides, Fr. Th. squamulose ; podetia cartilagineous- 

 corticate, from glabrous becoming verrucose or granulate-subpulveru- 

 lent, yellowish, at length cinereous-green ; the scyphiferous ones elon- 

 gated-turbinate, attenuate below ; scyphi cyathiform, dilated ; apoth. 

 scarlet. Fr. Lichenogr. p. 236. Lichen cornucopioides, L. Fl. Suec.
