106 HISTORY OF BRITISH MOSSES. 



an internal peristome of fine cilia has been described, which 

 lengthen out into a reddish membrane. 



2. Encalypta vulgaris, Hedw. {Common Extinguisher 

 Moss.) Stem short ; leaves oblongo-elliptical, obtuse, their 

 nerve produced a little beyond the summit; capsule cylin- 

 drical, smooth ; calyptra entire at the base. — Eng. Fl.p. 18 ; 

 Mull. Si/n. j)t. \. p. 516. 



On banks and wall-tops ; not so common in Scotland as 

 in' the south. Fr. March. Where this Moss is abundant 

 it is readily detected by the pale green of its cylindrical 

 calyptra, which adheres to it longer than in most other 

 Mosses. The peristome however is fugacious in the same 

 ratio, for unless examined when the lid is removed, its short 

 segments fall off at once, or indeed adhere to the lid. 



3. Encalypta ciliata, Hedw. {Fringed Extmguisher 

 Moss.) Stems more or less elongated ; leaves oblongo-acu- 

 miuate, their nerve produced considerably beyond the point ; 

 capsule cylindrical, smooth ; calyptra with a distinct fringe 

 at the base. — Eng. El. p. 18; Milll. Sijn.pt. \. p. 519. 



Moist rocks, and on the ground in mountainous districts. 

 Fr. Summer. The fringe surrounding the base of the ca- 

 lyptra is a prominent feature in the fruit of this Moss : it 

 does not seem to be a continuation of the calyptra, but is
