Description A common moss species that can be found where the conditions are wet and so look for it by streams in woodlands, or on wet heaths and bogs.  
ID Notes

This species is most abundant on wet, highly acidic heathland or bog. It is occasional in open woods where its presence indicates strongly acidic soil. In woodland however it is often recorded in error for its close relative Polytrichum formosum.
