Though appearing as if descending from C. squamosa, yet preserving as 

 it constantly does its own type, this may rightly be regarded as a distinct 

 species. At iirst sight, as observed by Xylander (Syn. p. 210), it looks 

 almost as if it were a folioiuse species of BcPumijres, or, when the apothecia 

 are sessile, as if it were a squamulose Lecidea with reddish aputhecia. 

 \\'hen more developed, it forms erect imbricate tufts of moderate size, 

 and when less developed and with the squamnles more scattered (terri- 

 co!e) it is rather widely expanded. The poielia, which arise from the 

 upper surface of the laciniye. are nalied or occasionally subverrucose, and 

 often so short that the apothecia and tlie spermogones are apparently 

 sessile on the leaflets. 



Hab. Among mosses on the trunks of trees and on rocks, on thatched 

 roofs, and also on the bare ground in maritime and upland tracts. — Distr. 

 fleueral and common throughout Great Britain ; rare in S. and W.

30. C. delicata Fliirke, Comm. Clad. (182S) p. 7.— Thallus 

 cgespitosely foliaceous at the base ; leaflets minute, narrowly eroso- 

 laciniate, granulato-leprose at the margin, groeuish-wbite or brownish- 

 grey ; podetia short, slender, somewhat thickened upwards, simple 

 or shortly divided at the apices, granulato-furfuraceous or minutely 

 squamulose (Tv-|- yellowish, CaCl — ). Apothecia generally conglo- 

 merate, brown or pale: spores oblongo-fusiform, 0,0] 0-15 mm. 

 long, 0,0035-40 ram. thick. — Cromb. Lich. Brit. p. 20 ; Leight.

From the preceding species, to states of which it beara con>iderable 

 resemblance, this is distinguished by the micriiphylline thallus, the sub- 

 leprose margins of the leaflets, and the gramdate or squamulose podetia. 

 More especially, however, and at once, it may with certainty be recog- 

 nized by the reaction with K. In suitable habitats it spreads somewhat 

 extensively, and is geuprally fertile. The ap >thecia are small, but are 

 sehhun seen >iniple.
