Notes:

Ecology: Open or forested premontane to páramo; boggy or seepy sites, on humus, rocks, base trunk of Blechnum. Elevation: 1000-3980 m (Venezuela: 1000-3625 m, Colombia: 1500-3850 m, Ecuador: 2090-3980 m, Peru: 2000-3400 m, Bolivia: 1800-3670 m). Distribution: Widespread, in the tropics mostly at mid to high elevations. Assigned to section Sphagnum.

Ecología: Distribución: Crece desde el premontano abierto o arbolado hasta el páramo; sitios pantanosos o con filtraciones, sobre humus, rocas, base de los troncos de Blechnum. Elevación: (415)1500-3980 m (Venezuela: 415-3625 m, Colombia: 1500-3850 m, Ecuador: 2090-3980 m, Perú: 2000-3400 m, Bolivia: 1800-3670 m). Distribución: Ampliamente distribuida, en los trópicos mayormente en elevaciones medias a altas. Asignada a la sección Sphagnum.

Plants large, red or red-tinged. Stem and branch cortical cells are delicately fibrillose; branch leaf hyalocysts are flat on both surfaces; chlorocysts in section are shortly elliptic and entirely included. Similar to S. alegrense which shows a slight development of short, vermiform ridges on the inner side walls of branch leaf hyalocysts and the cortical cells sometimes lacking fibrils.

Sphagnum magellanicum is by far the most commonly collected and named species, in large part due to the relative ease of identification. Synonyms include Sphagnum andinum Hampe and Sphagnum wallisii Müll. Hal. A collection from Vaupés, Colombia (Río Kananari, affluent of Río Apaporis, Cerro Isibukuri, Schultes & Cabrera13300 NY, det. HC), is possibly mislabeled (an entire series of Schultes collections were incorrectly labeled); until this species is definitely documented from Amazonas, all reported should be considered questionable for the eastern lowlands of Colombia. Collections named this species below 1000 m from Venezuela are likely incorrect.

Plantas grandes, rojas o matizadas con rojo. Células corticales de tallos y ramas delicadamente fibrilosas; hialocistos de las hojas de las ramas planos en ambas superficies; clorocistos en corte tranversal un poco elípticos y completamente incluidos. Así como en S. alegrense que presenta estrías vermiformes, cortas, poco desarrolladas, en las paredes internas de los hialocistos de las hojas de las ramas y células corticales algunas veces sin fibrillas.

Sphagnum magellanicum es la especie más comúnmente colectada y nombrada, en gran parte debido a su fácil identificación. Asignada a la sección Sphagnum. Una colección de Vaupés, Colombia (Río Kananari, afluente del Río Apaporis, Cerro Isibukuri, Schultes & Cabrera13300 NY, det. HC), posiblemente fue mal etiquetada; hasta que esta especie esté claramente documentada para Amazonas, todos los reportes deben ser considerados cuestionables para las tierras bajas orientales de Colombia.

Plants typically robust and pink or reddish, rarely green. Stem cortex 3-4 layered, epidermal cells elongate, fibrillose, 1 (2-4) rounded to elliptic pores Stem leaves flat, oblong to lingulate, ca. 2 mm, apex rounded and hyaline, margins fringed; hyaline cells not divided, fibrils absent, or fibrillose only at leaf apex, mostly resorbed on the outer surface or sometimes on both surfaces. Branches stout and tumid, in fascicles of 4-5 (2-3 spreading, 2-3 pendent), cortical cells 1-layered, cortex delicately fibrillose, sometimes with 1 large distal pore, Branch leaves broadly ovate, ca. 2 mm, deeply concave and cucullate, roughed on back and denticulate along a marginal resorption furrow; hyaline cells on the outer surface with rather numerous (2-5, rarely more) large, elliptic, ringed pores or occasionally pseudopores at the corners, also along the commissures, usually in 3’s at adjacent corners, passing into membrane gaps towards the leaf apex, on the inner surface with few (0-5) elliptic pores or pseudopores at corners and along the commissures in upper and lateral regions, often with 1 large rounded to elliptic pore at the upper ends; in cross-section green cells small, central and entirely included, short elliptic, hyaline cells plane on both surfaces.
