POPULAR HISTORY OF LICHENS. 



2. Cladonia deformis (clef amis, misshapen) is a large, 

 strong, coarse form, irregular in shape, rarely fertile, occur- 

 ring commonly on peaty ground and rotten wood in many 

 highland districts. It occurs also in the Arctic and Ant- 

 arctic regions. The scyphiferous podetia are elongate-tur- 

 binate or tubasforin ; the cylindrical ones often ventricose 

 or lacerate-fissured. (E. B. 1394.) 



3. Cladonia bellidiflora (hellus, beautiful, an&fos, a 

 flower). Podetia always cartilaginous, verruculose, squamu- 

 lose, slender or strong. Scyphi small, narrow, rarely pro- 

 liferous. Cylindrical podetia usually simple. Apothecia 

 often conglomerate or polycephalous. 



A common and beautiful species, growing on moist rocks 

 and on ground on many of our Highland mountains, as Ben 

 Nevis, Ben Lawers, Ben Lomond, and also on hills of minor 

 elevation, as the Cheviots and Pentlands. Its beautiful 

 scarlet apothecia render this one of the most handsome of 

 British Lichens. Steeping in water, we have found, destroys 

 the bright scarlet colour, however, changing it to a dull 

 brown ; this the student ought to bear in mind when he is 

 preserving specimens for the herbarium.
