IIab. Shady woods, on decayed logs, roots of trees, &c. 

 Common, but seldom in fruit. 



This species closely resembles the common European C. den- 

 droides, which is a native also of this country. In C. America- 

 num the capsules arc cylindrical, narrower, and much longer, 

 with longer-rostrate opercula : the teeth of the peristome are 

 differently shaped, being suddenly subulate from a short lanceo- 

 late base (not well represented in the figure) : the leaves of 

 the branches are more plicate, and the auricles at their base 

 arc much larger ; so that a leaf, when flattened, presents a some- 

 what hastate outline.
