144 ICONES MUSCORUM. 



Hab. In dry woods, on decayed logs, roots of trees, and the 

 ground. — Very common. 



C. cladorrhizans has until recently been considered a native 

 of North America only ; but the European C. Schleicheri is now 

 admitted to be the same species slightly modified. Of the two 

 plants, Prof. Schimper, in his excellent Synopsis Muse. Europ., 

 says : " Stirps americana differt notis pluribus ab europasa, sed 

 vix satis gravibus ut specie distinguatur."
