A rather anomalous plant, which, if it does not descend from C ceroi- 

 cornis, with which it somewhat afrrees in the character of the basal 

 squamules, is most probably referable to this species. The apothecia, 

 which in the absence of rijzlitly developed podetia are sessile on the leaf- 

 lets, are numerous.

b'. Ascyplnv. — Podetia not scyphiferous. 



20. C. turgida Hoffm. Deutsch. Fl. ii. (1 795) p. 124.— Tliallus 

 foliaceous at the base : leaflets large, laciniiform, variously divided 

 and crenate, sometimes few or evanescent, glaucous-green or whitish, 

 white beneath ; podetia laBvigato-corticate, turgid, elongato-turbinate 

 or cylindrical, subscyphiferous or perforate at the apices, the margin 

 dentato-radiate, glaucous or pale-green (Kf-(- yellowish, CaCl — ). 

 Apothecia brownish-red or pale ; spores oblong or oblongo-fusiform, 

 (J,010-15 mm. long. 0,0035-40 mm. thick.— Crorab. Lich. Brit.

When rightly developed (for the podetia are occasionally absent), this 

 is a very distinct species, which at first sight uiiolit be refeired to the macro- 

 phylline section. As stated, however, by Nylauder (Syn. p. 20-j), its 

 true affinity is with C. fur cat a in the present section. In the only two 

 British specimens the podetia are here and there sprinkled with smaller 

 leaflets. There are no apothecia present, but the spermogones are abun- 

 dant. 



Hah. On the ground among heather in subalpine regions. — Distr.

21. C. furcata HofFm. Deutsch. Fl. ii. (1793) p. 115.— Thallus 

 squamulose at the base or evanescent ; podetia slender, elongate, 

 glabrous, sparinglj' branched, glaucous-white or brownish-green, 

 uot perforate or subpervious at the axils, the branches somewhat 

 erect, attenuato-subulate and divergenti-furcate at the apices (K — ,
