--><span class="statement" id="st-undefined" data-properties=""><b>Plants </b>usually blackish green. <b>Stems</b> to 1(–1.5) cm, central strand present. <b>Stem</b> leaves spreading-incurved and twisted to incurved-appressed when dry, spreading to spreading-recurved and not keeled when moist, monomorphic, short-lanceolate or sometimes short-ovate to long-elliptic, broadly concave adaxially across leaf, usually 1–2.5 mm, base scarcely differentiated in shape to ovate, margins usually recurved at mid leaf, entire, apex broadly acute or occasionally narrowly so, not fragile; costa percurrent or ending a few cells below the apex, broader at mid leaf, occasionally weakly spurred, with a low adaxial pad of cells, adaxial costal cells quadrate, 4–6 cells wide at mid leaf, guide cells in 1–2 layers; basal laminal cells differentiated medially or across leaf, quadrate to short-rectangular, walls very thin and not perforated; distal laminal cells 7–12 wide, 1:1 or occasionally transversely elongate below, papillae usually distinct, low or simple to 2-fid, occasionally absent, lumens oval to rounded-quadrate, walls thin to evenly thickened, convex on both sides of lamina, 2-stratose in one or more rows along margins. <b>Specialized</b> asexual reproduction by multicellular tubers on proximal rhizoids. <b>Seta</b> 0.7–1 cm. <b>Capsule</b> 1–1.9 mm; peristome teeth 32, linear, weakly twisted, to 600 µm, occasionally rudimentary. <b>Spores</b> 11–15 µm. <b>Distal</b> laminal KOH reaction variously negative or yellow- or orange- or red-brown.</span><!--

|discussion=<p>In North American <i>Didymodon</i>, hydroids are found in the costae of <i>D. anserinocapitatus</i>, <i>D. australasiae</i>, <i>D. nevadensis</i>, <i>D. norrisii</i>, <i>D. umbrosus</i>, <i>D. revolutus</i>, and <i>D. vinealis</i>, and in these species the adaxial stereid band is usually absent in well developed specimens. Intergrades exist between <i>D. australasiae</i> and <i>D. umbrosus</i>, but the extreme forms are common and quite distinctive.</p>
