| Habit | 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. | Plants moderate-sized, fairly stiff-stemmed; green, brownish green, pale yellow, golden yellow, yellow and brown; capitulum hemispherical and not 5-radiate to somewhat 5-radiate in shade-grown or wet-grown forms. | ||||
| Stems | pale green to straw-colored; superficial cortical with a large round pore in distal portion of cell free from cell wall. |
pale green to pale brown, superficial cortex of 2 layers of moderately differentiated cells. |
||||
| Branch stems | green but proximal end sometimes red, with cortex enlarged with conspicuous retort cells. |
|||||
| Branches | not 5-ranked, quite terete, long, and slender Branch fascicles with 1– 2 spreading and 1–2 pendent branches. |
straight, mostly unranked, but can be 5-ranked in wet-growing forms, leaves little elongated at distal branch ends. |
||||
| Stem 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. |
triangular to lingulate-triangular, 0.8–1.2 mm, mostly appressed to the stem, apex acute to apiculate, hyaline cells mostly efibrillose and nonseptate. |
||||
| Branch leaves | 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. |
ovate-lanceolate, greater than 1.2 mm, straight, undulate and sharply recurved when dry, margins entire; hyaline cells on convex surface with usually 1 round pore per cell at apical end, on concave side with round wall thinnings in the cell ends and angles; chlorophyllous cells triangular and just reaching or slightly enclosed within the concave surface. |
||||
| Branch fascicles | with 2 spreading and 2–3 pendent branches. |

| Sexual condition | often monoicous. |
dioicous. |
||||
| Spores | 20–27 µm, finely papillose on both surfaces; proximal laesura less than 0.5 spore radius. |
25–31 µm; proximal surface finely papillose, distal surface pusticulate with bifurcated Y-mark sculpture; proximal laesura less than 0.5 spore radius. |

| Discussion | Subspecies 2 (2 in the flora). (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Sphagnum fallax can be distinguished from the closely related S. isoviitae by its sharply recurved branch leaves, as opposed to the leaves of the latter only slightly reflexed at their tips. See also discussion under 26. S. brevifolium and 46. S. splendens. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
