Distribution

Circumpolar. Most of Canada and AK, south NC, AL, AR, to CO. Also northern South America and Costa Rica.

Morphology

Robust pleurocarpous moss with erect-ascending stems to 16 cm high, from a decumbent base. Branches pinnately branched, julaceous, cuspidate-tipped. Paraphyllia absent, stem and branch leaves not differentiated.  Leaves loosely imbricate, concave, oblong-ovate; costa short and double; alar cells short-oblong, with thick, orange walls. Dioicous. Perichaetial leaves (surrounding the archegonium) erect, elongate, acuminate. Setae 2-4 cm long, reddish, smooth; capsules 2-2.5 mm long, smooth, curved, horizontal or inclined, annulus absent.

Notes

Most notable for its red stems that show through the semi-transparent leaves when moist. Does not survive fire well because it lacks rhizoids that penetrate the soil.
