The very erect and thickly-tufted mode of growth of this moss 
is very remarkable. In the disposition of the leaves it resembles 
Hypnum moniliforme, H. trifarium, H. flexile, and Leskea ert- 
coides ; and near the latter it will naturally enough rank, The 
whole plant is very brittle, but particularly the fruitstalk,
