--><span class="statement" id="st-undefined" data-properties=""><b>Plants </b>in loose to dense tufts, yellowish to dark green, glossy to dull. <b>Stems</b> 1.5–4.5 cm, sparsely tomentose with whitish to reddish brown rhizoids. <b>Leaves</b> erect-spreading or somewhat falcate-secund, rigid, erect below and flexuose above when dry, smooth, (3–)4–6(–7) × 0.5–0.8 mm, most of the leaf tips broken off, concave below to canaliculate above, from a lanceolate base to a long-acuminate, acute apex (when present); margins entire, sometimes slightly denticulate at apex; laminae 1-stratose or with some 2-stratose regions in patches between margin and costa; costa excurrent, 1/5–1/4 the width of the leaves at base, smooth or slightly rough on abaxial surface in distal half, abaxial ridges absent, with a row of guide cells, two weakly developed stereid bands above and below, not extending above the leaf middle, adaxial and abaxial epidermal layers of cells not differentiated or with a few cells enlarged in both layers; cell walls between lamina cells not or weakly bulging; leaf cells usually smooth; alar cells 1-stratose or with a few 2-stratose regions, well-differentiated, often extending to costa; proximal laminal cells rectangular to short-rectangular, not pitted or with few pits, (11–)33–42(–51) × (7–)9–10(–13) µm; median laminal cells regularly quadrate, not pitted, (9–)15–22(–26) × (5–)7–8(–11) µm; distal laminal cells small, quadrate, not pitted. <b>Sexual</b> condition dioicous; male plants as large as females; interior perichaetial leaves abruptly long-acuminate, convolute-sheathing. <b>Seta</b> 1–1.6 cm, solitary, yellow to reddish brown. <b>Capsule</b> 1.5–2.5 mm, straight, erect, smooth, slightly furrowed when dry, brown to reddish brown; operculum 1–1.5 mm. <b>Spores</b> 9–22 µm.</span><!--

|discussion=<p><i>Dicranum viride</i> has been reported from Alaska by I. A. Worley and Z. Iwatsuki (1970) and from Kentucky by J. A. Snider et al. (1988). It is a not uncommon species of the eastern United States and southeastern Canada. It rarely produces sporophytes and is distinctive because of the fragile, deciduous leaf tips, which probably serve as a means of asexual reproduction. It has on occasion been confused with 22. <i>D. fulvum</i>, which has nearly the same distribution, and rarely with 21. <i>D. fragilifolium</i> where their ranges overlap in the Great Lakes region. For distinctions see the discussions under those species.</p>
