--><span class="statement" id="st-undefined" data-properties=""><b>Plants </b>in loose tufts, dark green to yellowish green, dull to glossy. <b>Stems</b> 1–6 cm, tomentose with white or reddish brown rhizoids. <b>Leaves</b> often secund, straight or nearly so, often crisped when dry, smooth, 4–8 × 0.5–1 mm, lanceolate, acute, tubulose to apex; margins entire below, serrulate ot serrate near apex; laminae 1-stratose or sometimes 2-stratose on distal margins; costa excurrent, 1/5–1/3 the width of the leaves at base, abaxially papillose or toothed from leaf middle to apex, abaxial ridges absent, with a row of guide cells, stereid bands often present and well-developed in proximal part of leaf, absent in distal 1/4–1/3 of leaf, cells above and below guide cells large and thin-walled; cell walls between lamina cells not or slightly bulging; leaf cells smooth or often strongly papillose in distal half of leaf; alar cells 2-stratose, differentiated, often extending to costa, abaxial ridges absent; proximal laminal cells linear to rectangular, with or without pits, (26–)58–95(–130) × (10–)12–14(–16) µm; distal laminal cells quadrate, rounded, irregularly angled or short-rectangular, not pitted, (10–)15–26(–38) × (8–)9–11(–12) µm. <b>Sexual</b> condition dioicous; male plants as large as female plants; interior perichaetial leaves abruptly short-acuminate, convolute-sheathing. <b>Seta</b> 1–2.5 cm, solitary or sometimes 2, rarely 3, per perichaetium, yellow, rarely reddish yellow or brown with age. <b>Capsule</b> 1.5–3.5 mm, arcuate, inclined, often with a small struma, strongly furrowed when dry, contracted below mouth, yellow or yellowish brown, rarely reddish yellow or brown with age; operculum 1.5–2.5 mm. <b>Spores</b> 14–20 µm.</span><!--

|discussion=<p><i>Dicranum pallidisetum</i> has often been confused with <i>D. fuscescens</i>, being considered a form of it for many years (R. R. Ireland 1966). Unlike that species, which often occurs at low altitudes below 800 m, <i>D. pallidisetum</i> occurs predominately at high elevations, 800–2000 m, rarely being found as low as 500 m. It is distinguished from <i>D. fuscescens</i> by its tubulose leaves, usually 1-stratose or rarely 2-stratose on the margins, by its costa cross section that shows no stereid bands in the distal 1/3 of the leaf, and by its yellow or yellow-brown capsules that are sometimes 2–3 per perichaetium. In contrast, <i>D. fuscescens</i> has leaves keeled above, usually 2-stratose on both margins, rarely 1-stratose on one margin, stereid bands present throughout the leaf and dark brown to reddish brown capsules that are solitary or rarely 2 per perichaetium.</p>
