This is another new Moss discovered by Professor Hornschuch, 
differing in so many respects from any other known moss, that it 
is hard to say to which it approaches the nearest. The stems 
and foliage most resemble small specimens of Bryum julaceum ; 
but the fructification is very remarkable, having the fruitstalk 
curved below the capsule, like the neck of a swan, and the capsule 
either inclined or pendent according to the degree of curvature.
