Circumboreal. Labrador west to AK, south to FL, AR, MT, and CA.

Morphology

Coarse, shaggy moss occurring in loose tufts. Stems decumbent or erect, to 20 cm, irregularly branched and wide-spreading; stems and branches orange-red. Leaves gradually tapered to a broad, flat tip, erect or spreading, irregularly plicate, orange where inserted; back of leaves roughened by projecting cell ends (prorulose); costa double. Seta 1.5-4.5 cm long; capsules red-brown, horizontal, asymmetric, short-necked.

Notes

The common name is one suggested by Crum. Unfortunately most mosses do not have common names in general use, likely because most people can not tell one moss from another.
