| 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. |
Plants moderate-sized to robust, usually soft and lax, sometimes moderately stiff, capitulum typically enlarged and flat-topped, ± stellate; green to golden brown, unshaded plants often reddish purple, plants with metallic sheen when dry. |
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. |
leaves triangular-lingulate to broadly lingulate, 0.9–1.3 mm, apex broadly rounded to obtusely angled, border very strong and broad at base (more than 0.4 width); hyaline cells rhombic, efibrillose, most 0–1-septate. |

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.) |
Sporophytes of Sphagnum subfulvum are common. This species is associated with S. centrale, S. contortum, S. teres, and S. warnstorfii. Although it is normally more minerotrophic, S. subfulvum does occasionally (in Newfoundland) occur in the same mires as S. flavicomans. The latter lacks the metallic sheen of S. subfulvum and its stem leaves are not as narrow and acute. In some forms S. subfulvum may develop a purplish gloss that may lead to confusion with S. subnitens but the color of that species has a definite red component and its stem leaves are narrower and more sharply pointed than those of S. subfulvum.
