This moss was confounded with Teesdalei on the continent, but it is really 

 much nearer to litoreum, from which it differs chiefly by the form of the leaf ; 

 this tapers into an acute point, obscurely serrated, and not acutely acuminate, 

 the leaf-cells also being longer and laxer. It was first found by Bridel, at 

 Rome in 1806.
