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 first sight, as observed by Nylander (Syn. p. 210), it looks 

 almost as if it were a foliolose species of Baomyces, or, when the apothecia 

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

 When more developed, it forms erect imbricate tufts of moderate size, 

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

 cole) it is rather widely expanded. The podetia, which arise from the 

 upper surface of the laciniae, are naked or occasionally subverrucose, and 

 often so short that the apothecia and the spermogones are apparently 

 sessile on the leaflets. 



Hob. 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.

30. C. delicata Florke, Comm. Clad. (1828) p. 7. Thallus 

 caespitosely fbliaceous at the base: leaflets minute, narrowly eroso- 

 laciniate, granulato-lcprose at the margin, greenish-white or brownish- 

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

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

 equamulose (K + yellowish, CaCl ). Apothecia generally conglo- 

 merate, brown or pale; spores oblongo-fusiform, 0,010-15 mm. 

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

From the preceding species, to states of which it bears considerable 

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

 leprose margins of the leaflets, and the granulate 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 generally fertile. The apothecia are small, but are 

 seldom seen simple.
