One of our commonest British Lichens ; it differs little from the 
preceding species except in the absence of colour reaction with potash 
and in the generally smaller lighter-coloured and less tomentose 
podetia. Forms fenwis and grandis represent the somewhat more 
extreme developments. Jn f. lappacea the podetia are more crowded 
and branched. Cladonia impexa is whitish and almost translucent in 
appearance, but otherwise like the species; the translucent character 
appears occasionally both in this species and in the preceding. It 
is more than probable that Lichen rangiferinus of the older writers 
refers to this, the much commoner species.
