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 moderate-sized, upright but weak-stemmed; golden brown to dark brown; capitulum distinct and often with strongly curved branches. |
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 triangular-lingulate to lingulate; 0.8–1.2 mm; apex rounded and sometimes erose; hyaline cells non-septate or sometimes septate, usually fibrillose in distal 1/2 of leaf, convex surface with very small pores (ca. 2 µm) along commisures and free, concave surface with fewer commissural pores. |
Branches | weakly to strongly 5-ranked. |
turgid and often strongly curved. |
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-lanceolate; 1.4 or more mm; mostly subsecund; hyaline cells on convex surface with numerous small (2 µm or more) pores along the commissures and sometimes free, concave surface with no pores or fewer small pores along the commissures. |

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.
