Apart from the etomentose podetia this dift'ers but little in external 

 form and appearance from C. rangiferina. of which it has generally been 

 regarded only as a variety with somewhat imcertain characters. By the 

 aid of the chemical reactions, however, we are now able to distinguish it 

 in all its different states, and to assign to it its proper specific value. In 

 this country it is comparatively rare in a fertile condition.
