Additional Information at NatureServe

Diagnostic Characteristics:
A densely tufted species, forming tight hummocks up to 20-40 cm tall, composed of mostly unbranched, somewhat grey-green, erect shoots. These bear short (about 1 cm long), evenly spaced, narrowly spearhead-shaped leaves with a reddish-brown tip, and untoothed, inrolled margins. These are held away from the stem when moist, and appressed to each other when dry. The stems are densely matted together below with an off-white felt of rhizoids. The shortly rectangular, sharply 4-angled capsules are borne on a rather slender, reddish seta that is 3-4 cm long. These are produced in summer, albeit less commonly than those of other Polytrichum species.

Grazing or browsing pressure, vegetation removal, or hydrologic changes (i.e. stream alterations road construction) would be detrimental.
