Habit | Plants small to moderate-sized, slender, fairly stiff but soft, capitulum flat-topped and stellate; deep maroon-red to variegated red and yellowish green, lacking metallic sheen when dry. | Plants typically small and slender, larger and compact in the Arctic, capitulum small to moderate-sized, often with a conspicuous terminal bud; green, yellowish brown to brown; without metallic lustre when dry. | ||||
Stem(s) | leaves lingulate-triangular to lingulate, 1–1.4 mm, apex broadly rounded but becoming acute in hemiisophyllous forms, border strongly developed at base (more than 0.25 width); hyaline cells rhombic and 0–3-septate with some cells in leaf midregion 2–septate. |
leaves spatulate to broad-spatulate, 0.8–1.5(–2) mm, strongly lacerate across the broad apex and often part way down the margins, border scarcely to strongly broadened at base (0.25 width of base or less); hyaline cells rhomboid, efibrillose and often 1–2-septate. |

Branches | weakly to strongly 5-ranked. |
not 5-ranked, quite terete, long, and slender Branch fascicles with 1– 2 spreading and 1–2 pendent branches. |
||||
Branch leaves | ovate to ovate-lanceolate, 0.9–1.2 mm, concave, subsecund on some branches, apex involute; hyaline cells on convex surface with numerous round to elliptic pores along the commissures, grading from small round pores near apex to round pores near base, on concave surface with large round pores in proximal portions of leaf. |
ovate to ovate-lanceolate; 1.1–1.5(–2) mm, slightly concave, straight; apex involute; margins entire; hyaline cells on convex surface with numerous pores along the commissures grading from small pores near leaf apex to large pores at base, concave surface with large round pores at leaf apex and along margins. |

Discussion | Sporophytes are uncommon in Sphagnum rubellum. This common species is associated with S. angustifolium, S. capillifolium, S. fallax, S. fuscum, S. magellanicum, S. papillosum, S. recurvum, and S. tenellum. Inland, it has a greater tendency to form extensive carpets and floating mats than hummocks. See also discussion under 65. S. andersonianum, 68. S. bartlettianum, and 86. S. talbotianum.
