_The contorted podetia and the often incrassate apices of their branches 
distinguish this form. The podetia are frequently also more or less 
squamulose and furfuraceous in the lower portion, In our specimens a 
few young apothecia only are present.

This is distinguished by the radiate margins of the scyphi; but the 
ascyphous podetia are very similar to those of the preceding variety, 
with which it seems to be confluent. In luxuriant specimens the scyphi 
are expanded, with the subulate fimbriz more elongate. The apothecia 
are not present in our specimens, but the spermogones are frequent. 
Hab. On the ground in upland districts——Dizstr. Probably general in 
hilly tracts of Great Britain and Ireland, though as yet seen only 
from comparatively few localities——B. M.: Near Norwich, Norfolk;

11. C. gracilis Hoffm. Deutsch. Fl. ii. (1795) p. 119.—Thallus 
sparingly squamuloso-foliolose at the base; squamules olive-green 
or brownish above, whitish beneath, often evanescent; podetia 
elongate, slender, corticate, glabrous, simple or branched, subulate 
or scyphiferous at the apices; scyphi narrow, denticulate at the 
margins, pale-greyish or pale-greenish, occasionally subspadiceous
