178 HOW TO KNOW THE MOSSES 



Dichelyma capillaceum is usually found at the edge 

 of ponds and in very wet, swampy places. The dis- 

 tinguishing characteristics are the long hair-like leaves, 

 sometimes turned to one side, usually curved at the tips 

 of the branches y with the capsule protruding from the long 

 leaves that wrap around the seta. If this species is fruited, 

 the above character of the capsule and seta at once 

 separate it from other mosses growing in similar situ- 

 ations. Sterile plants may be distinguished from Fon- 

 tinalis by the curved leaves, giving the ends of the 

 branches a hooked appearance. Dichelyma is found in 

 stagnant water, while Fontinalis grows in flowing 

 water. See Drepanocladus (p. 213) and Amhlystegium 

 (p. 208).
