--><span class="statement" id="st-undefined" data-properties=""><b>Plants </b>moderate-sized to large, usually quite compact; reddish brown and often yellow flecked with red-brown; in dense stands forming large and tall hummocks. <b>Stems</b> brown, superficial cortical cells with spiral reinforcing fibrils clearly visible, usually 2 or more pores per cell, comb-fibrils lacking on interior wall. <b>Stem</b> leaves 1.2–1.6 × 1 mm; rarely hemiisophyllous; hyaline cells nonseptate or more typically mostly septate, comb-lamellae present on interior wall. <b>Branches</b> clavate, tapering to short point, tightly imbricate at proximal end to somewhat spreading at distal end in less compact forms. <b>Branch</b> fascicles with 2 spreading and 1 pendent branch. <b>Branch</b> stems with cortical cell comb-lamellae visible on interior wall, conspicuous funnel-like projection on interior end walls extending to next cell less than one half its length, pores in superficial wall restricted to leaf bases. <b>Branch</b> leaves ovate-elliptical to elliptical, 1.5–2.1 × 0.8–1.4 mm; hyaline cells on convex surface with numerous moderate-sized round pores along the commissures, comb-lamellae present throughout most of leaf; chlorophyllous cells broadly triangular in transverse section and well-enclosed on the convex surface, end wall not thickened. <b>Sexual</b> condition dioicous. <b>Capsule</b> with scattered pseudostomata. <b>Spores</b> 23–28 µm; coarsely granulate on both surfaces; proximal laesura more than 0.50 spore radius.</span><!--

|discussion=<p><i>Sphagnum austinii</i> is usually easily recognized in the field by its strongly imbricate and clavate branches. It forms very dense and often tall hummocks with a distinct deep golden brown color. In contrast to the view stated by H. A. Crum (1997), this species has an ecology and distribution quite distinct from those of <i>S. affine</i>. <i>Sphagnum affine</i> is a minerotrophic species that does not even occur in the Pacific coast region, where <i>S. austinii</i> is quite prominent.</p>
