| Plants small or less frequently moderate-sized, slender, capitulum flat-topped and stellate; green or dark purplish red and green, rarely green throughout, often with a distinctive bluish cast when dry. |
Plants small to moderate-sized, compact to fairly slender, normally stiff and erect; capitulum typically hemispherical; in exposed sites red, mottled red and green, in shaded sites green forms are common; without metallic lustre when dry. |
leaves triangular-lingulate to lingulate, 1.1–1.4 mm, apex broad-rounded to narrowly truncate, border very broad at base (more than 0.3 width); hyaline cells efibrillose, rhombic, mostly 1-septate but can be non-septate. |
green to red; superficial cortical cells aporose Stem leaves lingulate-triangular, 1.2–1.6(–1.8) mm, apex ± involute; border entire and broadened to about 0.25 the width of the base; hyaline cells S-shaped, 0–1-septate, usually fibrillose in distal portion of leaf. |
long and tapering, usually strongly 5-ranked. |

Sporophytes are uncommon in Sphagnum warnstorfii. This is one of the most minerotrophic species of the flora, is hygrophytic, and has a very broad niche. The most commonly associated vascular plants are Thuja occidentalis, Abies balsamea, and Picea rubens. Bryophytes typically associated with it are S. centrale, S. squarrosum, S. teres, Calliergonella cuspidata, and Campylium stellatum. This species is perhaps most similar to S. bartlettianum, with which it has small range overlap. Sphagnum warnstorfii has a shorter and less sharply pointed stem leaf and the red color with a characteristic bluish caste compared to the crimson red of S. bartlettianum. See also discussion under 81. S. russowii and 86. S. talbotianum. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Sporophytes are fairly common in Sphagnum capillifolium. This species is most common and abundant in ombrotrophic heath vegetation associated with S. angustifolium, S. fallax, S. fuscum, S. magellanicum, S. rubellum, Polytrichum commune, and P. juniperinum. It can be distinguished from most other red species of sect. Acutifolia with which it co-occurs by its lack of 5-ranking in the branches. Sphagnum subtile is a forest and non-hummock forming species that has a distinctly shorter and more triangular-lingulate stem leaf. The stem leaf border on S. subtile is also more strongly bordered. Sphagnum tenerum, which geographically overlaps S. capillifolium only very minimally, has much more turgid branches and a generally more robust look. The stem leaf of S. tenerum is triangular-lingulate as compared to the lingulate- triangular stem leaf of S. capillifolium. See also discussion under 84. S. subnitens and 87. S. tenerum. The names Sphagnum acutifolium Schrader and S. nemoreum Scopoli (doubtful name) have also been used for this taxon. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
