POPULAR HISTORY OF LICHENS. 



mon base, linear-laciniate, glaucous, lacunose on both sides, every- 

 where of similar colour, having a cartilaginous cortical layer, fre- 

 quently sorediiferous, originally erect, frequently pendulous. Apo- 

 thecium scutellate, subpedicellate, varying in site. Thalarnium 

 always naked, of similar colour to thallus, or pale flesh-coloured. 

 (Name derived from ramale, a dead twig, probably in allusion to 

 a very common habitat of its species.) 



1. Bamalina pqllinaria (pollen, fine flour or meal). 

 Thallus flaccid, lacero-laciniate ; lacinise flattened, sub-lacu- 

 nose ; soredia somewhat large, usually scattered ; apothecia 

 sub-terminal. (E. B. 1607.) 



Habitat : the trunks of trees and wooden palings, in or 

 about lowland and sub-alpine woods ; but it is a compara- 

 tively rare species in Britain. 



2. Eamalina earinacea (farina, meal or flour). Thal- 

 lus flaccid, somewhat smooth and shining, multifid-laciniate ; 

 laciniae linear-attenuate, flattened ; soredia small, white, fim- 

 briate ; apothecia terminal and lateral, but very rare. (E. B. 

 889.) 



A very common species, growing on our forest-trees and 

 hedges. We see no reason for dissociating it from the fol- 

 lowing species, of which it appears to constitute a frequent 

 form, and along with whose varieties it may often be met 

 with on the same habitat.
