Though appearing as if descending from C. sguamosa, 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 Beumyces, or, when the apothecia 
are sessile, as if it were a squamulose Lectdea 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 lacinie, are naked or occasionally subverrucose, and 
often so short that the apothecia and the spermogones are apparently 
sessile on the leaflets.

30. C. delicata Florke, Comm. Clad. (1828) p. 7.—Thallus 
cespitosely foliaceous at the base; leaflets minute, narrowly eroso- 
laciniate, granulato-leprose 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 
squamulose (K+yellowish, CaCl—). Apothecia generally conglo- 
merate, brown or pale; spores oblongo-fusiform, 0,0]0-15 mm.

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 grahulate 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.
