HAB. In woods; not very frequent in fructification, but 

 found in that state near Manchester, by Mr. Hobson. 

 About Oxford. Mr. Oglander. And in several sub- 

 alpine spots in Scotland. 



The columella of this moss is protruded, and reaches the top 

 of the lid, which, when the capsules are ripe, and in a dry state 

 of the atmosphere, it raises up, turning in a spiral manner ; 

 and then, perhaps, permitting the discharge of the seeds. If 

 in this state, moisture be applied to the mouth of the capsule, 

 the lid on the top of the columella will descend, as this last 

 performs a spiral volution, and the capsule becomes completely 

 closed again. The segments of the interior peristome being 

 cleft at the base, has induced Weber and Mohr to make a dis- 

 tinct genus of this moss.

HAB. On trees and rocks. 



The nerve is, as Mohr has justly observed, sometimes forked. 

 In habit it somewhat resembles the two last species, but is con- 

 siderably smaller, and the stems are leafy throughout
