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.
