--><span class="statement" id="st-undefined" data-properties=""><b>Plants </b>slender to moderately robust, capitulum flat-topped to somewhate convex, terminal bud rather conspicuous, slightly to distinctly stellate; green to variegated green and brown-red to red-brown, lacking metallic sheen when dry. <b>Stems</b> pale or pale with red-brown portions particularly during late autumn; superficial cortical cells mostly with one ± circular to transversely elliptical pore close to distal cell wall, occasionally superficial cells with 2(–3) pores with most occupying more than half the cell width. <b>Stem</b> leaves broadly lingulate-spathulate to spatulate, widest at base and/or distal third, usually narrower in the mid region, 1–1.3 mm, apex narrowly to broadly truncate and ± fimbriate-lacerate, border narrow distally and expanded proximally to 0.25 width or more; hyaline cells efibrillose, irregularly rhombic to subquadrate, many cells 2–4-septate. <b>Branches</b> unranked. <b>Branch</b> fascicles with 3(4–5) spreading branches and 1–2 pendent branches. <b>Branch</b> leaves ovate-lanceolate, 1.1–1.4 mm, slightly concave, straight, apex involute; hyaline cells on convex surface grading from aporose to few small round pores near apex to numerous semi-elliptic pores along commissures in middle and base of leaf, concave surface with a few large irregular to circular pores (1–4) occupying most of the cell width. <b>Sexual</b> condition autoicous. <b>Spores</b> 20–27 µm, moderately granulate-papillose on both surfaces, distinct raise Y-mark sculpture on distal surface; proximal laesura less than or equal to 0.5 spore radius.</span><!--

|discussion=<p>The sporophytes of <i>Sphagnum rubiginosum</i> are common. The geographic distribution is unclear because of the species’ recent description and possible confusion with <i>S. girgensohnii</i>. It is clearly distinct from <i>S. girgensohnii</i> in coloration, number of spreading branch fascicles, the common occurrence of sporophytes (rarely found with <i>S. girgensohnii</i>, and spore morophology. The conspicuous three spreading branches will separate this from all species of sect. Acutifolia except <i>S. quinquefarium</i>. The latter has 5-ranked branch leaves, while those of <i>S. rubiginosum</i> are unranked.</p>
