Hypnum pratense is a temperate to boreal circumpolar species, scattered largely north of the 35 parallel of latitude, but not frequent in the Arctic; plants produce sporophytes infrequently in spring and summer. Plants of H. pratense are strongly glossy with few or no rhizoids, the apical laminal cells are considerably shorter than the medial cells, and the capsules are furrowed when mature and dry. For additional comments, see discussion under 14. H. lindbergii.
