OF GREAT BEITAIN. 55' 



The different reaction keeps this distinct from gracilis, verticillata, and 

 sobolifera. 



F. stipata, Nyl. (in Flora 187& p. 239) basal squamse elongate, 

 sublinear, crenato-incised, erect, stipate, rarely fertile. 

 On rocks. 

 Ireland :— Kylemore, co. Galway, Mr. Larbalestier. (1876.) 



6. G. cariosa, FJk. thallus ashy-green, scales minute, crenate, 

 more or less investing the base of the podetia ; podetia whitish, 

 | — 1 in. high, cylindrical, dilated upwards, carioso-cancellate or 

 eroso-lacunose, granulato-verrucose, scyphi digitato-partite, fastigiate. 



On the earth, rare. 1832. 



The re-action separates from pyxidata, pityrea, decorticala, degenerans, botrytes 

 and mitrula. 



I have seen small specimens from Ireland, similar to " forma juvenilis," Hepp 

 541 and 542, and probably referable to symphycarpa, Ach ! in hb. Kew. L. 

 microphyllus, E. Bot. 1782 is referable to leptophylla of C. pyxidata.

7. 0. delicata, Flk. thallus caespitose, microphylline, white or 

 brownish-grey, leaflets minute, eroso-laciniate, lacinise narrow, 

 minutely incised or crenate and granular at the margins; podetia 

 slender, simple or divided, J in., thickened upwards, cartilaginous, 

 glabrous, longitudinally ribbed or fissured, more or less with 

 granular scales. 



On old rails, not common. 



The reaction (K + C— ) distinguishes this from ccespititia, Flk. (K — C — ), 

 from squamosa, Hffm. (K — C — ), from pyxidata, var. pityrea, (K — C — ), and 

 that and the characters of the podetia, would seem to ally this with cariosa.
