This very handsome moss comes in general habit nearer to our
Hypnum dendroides than to any other that I know; yet it is
very different even from that. In nothing, however, is it so remarkable
as in the large cylindrical deeply sulcate capsule, and
the long perichætial leaves compared with the shortness of the
fruitstalk.
