POPULAR HISTORY OF LICHENS. 



or ramose, bifurcate, axils seldom gaping, fertile ones digi- 

 tately divided. 



The var. uncialis, which is slender, rigid, subimperforate, 

 with stellulate or bifurcate extremities, is common on the 

 ground among moss on hill-heaths in lowland and alpine 

 districts. We have frequently observed the base of the po- 

 detia in this variety, especially in large specimens from north- 

 ern countries, of a beautiful blood-red tinge, as is the case 

 in Cetraria nivalis and other Cetrarias. A similar discolo- 

 ration sometimes exists in other ochroleucous Cladonias. 



10. Cladonia furcata (/urea, a fork). Podetia aphyl- 

 lous or squamulose, glaucous or brownish-green. Cylindrical 

 ones fruticulose, subdichotomously ramose : axils and fertile 

 extremities subperforate ; fertile subcorymbose ; sterile su- 

 bulate, bifurcate. Thallus minute, crisped-lacinulate, rarely 

 conspicuous. 



Common on ground, among moss, on heaths, and in woods 

 in lowland and subalpine regions. 



11. Cladonia eangipeeina (Cervus rangi/er, the rein- 

 deer). Podetia very slightly farinose, at length verruculose, 

 always aphyllous, greyish, fruticulose and very ramose, all 

 cylindrical, subperforate at axils ; extreme ramules radiate ; 

 fertile erect, cymose ; sterile uodding. It may be know r n
