NEW BRITISH MOSSES. 



By JAMES STIRTOX, M.D., F.L.S. 



This year I picked up, in localities widely apart, three mosses 

 whose characteristics are not reconcilable with those of any mosses 

 hitherto known to me, or with those described in works on the 

 subject accessible to me. 



The first is from Ben Lawers, where it was found in July, at an 

 elevation of about 3,000 feet. 



Didymodon turgescens ; densely caespitose or even pulvinate, 

 very much resembling at first sight tufts of Tortula fragilis, but 

 softer ; stems simple or dichotomously divided, varying in length
