GEORGIACEAE 155 



Capsule erect, long-cylindrical; reddish-brown; mature in 

 spring. 



Operculum short-beaked. 



Peristome of only four teeth, sometimes large enough to be 

 seen with the unaided eye when plants are held to the light. 



Range, Canada and the northern United States; Europe; 

 Asia. 



Georgia pellucida is one of the most common mosses. 

 Its favorite habitat is decaying logs and old stumps. It 

 is distinguished from other mosses of similar location 

 by the slender stems with very small erect leaves. If the 

 stems, with terminal leaves forming a cup-like cluster, 

 are present, or if the peristome of four teeth can be made 

 out, no other characters are necessary for identifica- 

 tion. If the plants are found on the ground compare 

 Ditrichiim (p. 78) and Barbula (p. 105).
