This apparently descends from C. coccifera, of which it is probably 

 only a peculiar and diminutive condition. Thepodetia are usually about 

 2 lines, rarely \ in. high, with the scyphi either not at all developed or 

 very narrow. The apothecia are numerous, becoming at length more or 

 less continent. 



Hab. On peaty soil and putrid stumps of trees in mountainous districts. 

 Distr. Found only sparingly in the S.W. and Central Highlands of 

 Scotland. B. M. : Barcaldine, Argyleshire ; Rannoch, Perthshire. 



Subsp. C. pleurota Croinb. Grevillea, xi. (1883) p. 114. Pode- 

 tia turbinato-scyphiferous, pulverulent, yellowish-white or pale- 

 greenish ; scyphi dilated, subentire or rarely proliferous at the 

 margins. Apothecia solitary, subpedicellate. Cladonia cornuco-

Though sometimes regarded as a variety of C. deformis, its affinity is 

 undoubtedly with C. coccifera, to which it holds a somewhat analogous 

 relation as C.fonbriata to C. py.iidata. Since, however, as pointed out 

 by Nylander, Lich. Scand. p. 59, it occurs also with the podetia corticate 

 at the base, it can scarcely be regarded as a distinct species. Thepodetia 

 in states with larger scyphi have the margin at length sinuate and 

 radiate. With us it is only smaller and less typical states that are 

 usually seen, and the apothecia are rarely present. 



Hub. On the ground among mosses in shady places, on moorlands, 

 and in woods in upland districts. Distr. Apparently local and scarce in 

 S.W. and N. England, the W. and N. Grampians, Scotland, and S.W. 

 Ireland. B. M. : Dartmoor, Devonshire ; St. Breward, Cornwall ; Ayton, 

 Cleveland, Yorkshire. Barcaldine, Argyleshire ; Rannoch, Perthshire ; 

 Glen Callater, Braemar, Aberdeenshire. Killarney, co. Kerry. 



32. C. bellidiflora Florke, Clad. (1828) p. 95. Thallus foliaceo- 

 sijuarnose at the base ; leaflets somewhat firm, variously divided or 

 crenato-incised, straw-coloured above, white beneath ; podetia cor- 

 ticate, subsimple, squamoso-foliaceous. cylindrical, or scyphiterous, 

 often somewhat ventricose in the middle, straw-coloured or greyish- 

 green ; scyphi narrow, sometimes divided when not rightly deve- 

 loped (K , CaCl ). Apothecia somewhat large, often conglo- 

 merate; spores 0,009-11 mm. long, about 0,0035 mm. thick.
