Clad. p. 108. — /?. clavata, Fr. ; podetia ventricose, subulate at the 

 apices or branched, substerile. Fr. I. c. 



On the earth, decaying logs, dead wood, and rocks ; common in 

 mountainous districts, and fertile ; New England. Pennsylvania, Muhl. 

 Ochrocarpous states of this species, in which the bright scarlet of the 

 apothecia is changed to a pale yellow, occur in our mountains, but less 

 frequently than similar forms of C. Floerkiana. 



27. C. digitata, Hoffm. Th. squamulose ; podetia cylindrical, be- 

 coming ochroleucous-pulverulent above ; scyphi narrowed, with an in- 

 curved, entire margin, becoming at length ampliate, and the margin 

 somewhat proliferous-palmate ; apoth. scarlet. Fr. Lichenogr. p. 240. 

 Sclicer. ! Spicil. p. 22. Floerk. ! Clad. p. 102. Lichen digitatus, L. 

 Icon, Laur: in Sluriji's Fl. t. 15, 16. — a. plalyphyllina ; lobules of 

 the thallus dilated, somewhat entire ; scyphi mostly entire. Fr. I. c. — 

 (?. microp7iylli7ia ; squamules of the thallus rather small ; scyphi mostly 

 palmate-ramose. Fr. I. c. 



Decaying trunks, and moist earth among mosses, in mountainous dis- 

 tricts, fertile ; New England. 



28. C. deformis, Hoffm. Th. squamulose ; podetia elongated, cy- 

 lindrical or ventricose, becoming sulphureous-pulverulent above ; scyphi 

 somewhat narrow, becoming at length cupulseform and dilated, with 

 an erect, crenate-dentate margin ; apoth. scarlet. Fr. Lichenogr. p. 

 239. Schcer. ! Spicil. p. 23. C. crenulata, Floerk. ! Clad. p. 105. 



On the earth, common upon mountains, a conspicuous Lichen, fer- 

 tile ; New England. Northward to Arctic America, Rich. Green- 

 land, Floerke. 



29. C. sulphur ina, Michx. (sub Scyphoph.). Podetia simple, at first 

 very simply and slightly scyphiform, thick, submembranaceous, at 

 length subclavate-elongated, smooth, the apices finally irregularly sub- 

 divided, and rimose-perforale, hoary-sulphureous ; fertile scyphi small ; 

 apoth. confluent, black-fuscous. Scyphophorus sulphurinus, Michx. Fl. 

 2, p. 328. Cenomyce, Ach. Lichenogr. p. 557. Ach. Syn. p. 265. 



On the earth, Canada, Michaux ! Fries. This is the " Lichen coc- 

 ciferus; major. Dill. t. 14, f. 6, M," of Michau.x's herbarium, the speci- 

 mens appearing to me, at the time I examined them, to resemble some 

 states of C. deformis. Fries observes incidentally (Lichenogr. p. 237) 

 upon Canada specimens (' specimina authentica Canadensia') of Mi» 

 chaux's Lichen, that the podetia do not become squamulose, that it has
