Cladonia crispala Fink, The Bryologist 7 : 57, 1904. 



Cladonia furcala crispala Tuck. Syn. N. Am. Lich. I: 247. 1882. 



Primary thallus persistent or finally dying, of medium sized, 

 digitate-laciniate or crenate, ascendant squamules, rather densely 

 clustered, and forming a crust; color greenish and greenish brown; 

 white beneath. 



Podetia rising from the surface of squamules, sometimes dying 

 basally but growing above, from short to medium length, sub- 

 cylindrical, with few branches; these sub-erect, with axils com- 

 monly dilated; surface smooth or becoming granulose or somewhat 

 squamulose; more or less cup-bearing, or terminating bluntly, or 

 rarely awl-like. Cups small, dilated, perforated, usually with pro- 

 liferate margins. 



Apothecia small, solitary or becoming aggregate, at the ends of 

 the proliferations or on the ends of short stalks which form a ragged 

 margin to the cups; brown to very dark brown. 



On earth in the mountains, apparently not common. Generally 

 distributed over the northern part of North America and found in 

 all parts of the world except Africa.
