--><span class="statement" id="st-undefined" data-properties=""><b>Plants </b>medium-sized to large, in large, dense or loose tufts or mats, grayish olive or olivaceous in the distal part, brown or grayish proximally. <b>Stems</b> (1–)3–10(–13) cm, creeping, decumbent to ± erect, mostly pinnately branched with short, tuft-like branchlets, usually distinctly recurved at the apex. <b>Leaves</b> imbricate, not altered on drying, recurved when moist, ovate-lanceolate to subtriangular, indistinctly plicate, 2–3.2 × 0.8–1.2 mm; margins broadly recurved throughout; apices sharply carinate, most often piliferous, awns recurved to reflexed, subulate, strongly denticulate, mostly long-decurrent, slightly to distinctly papillose distally, strongly papillose basally with high and narrow papillae; costa percurrent, situated at the base of a moderately deep, wide-angled channel and strongly flattened basaly, 75–100 µm wide; basal laminal cells long-rectangular, 20–50 × 4–6 µm, moderately thick-walled, nodulose, papillose with large papillae, except for 1–4 rows of epapillose cells at the insertion; alar cells hyaline, thin-walled in 3–5 rows, forming a sharply delimited, convex group; supra-alar cells short, thick- and sinuose-walled, forming non-transparent border of 6–10 cells; medial and distal laminal cells subquadrate to rectangular, 6–20 × 5–8 µm, distinctly papillose. <b>Inner</b> perichaetial leaves hyaline, piliferous. <b>Seta</b> brown, glistening, 10–15 mm. <b>Capsule</b> brown, long-cylindric, 1.4–1.8 mm, sulcate when dry; peristome teeth 650–800 µm long, reddish brown to red, split to the base into 2 filiform prongs, densely papillose. <b>Spores</b> 9–11 µm.</span><!--

|discussion=<p><i>Niphotrichum elongatum</i> has only recently been formally described as a distinct species. Although it was distinguished at that level by several bryologists of the early eighteenth century, it subsequently fell into oblivion and was merged with <i>N. canescens</i>. It is very distinct, though closely related to <i>N. ericoides</i>. In contrast to the latter, it is a more southern taxon, and in North America does not extend to the Arctic, reaching its northernmost locality on Gilbert Island in southeastern Alaska. Apart from a few collections from the southernmost tip of Greenland, it has been found only once at lat. 70º N in East Greenland. It grows in habitats similar to those of <i>N. ericoides</i>, with which it often occurs in mixed stands, but the latter generally favours drier, warmer, and more exposed microhabitats than the former.</p>
