--><span class="statement" id="st-undefined" data-properties=""><b>Plants </b>small to large, ± glaucous, green to rusty brown. <b>Stems</b> with branches erect to arcuate, sometimes attenuate to flagellate distally; central strand cells differentiated or not; pseudoparaphyllia absent in all but 2 species. <b>Branch</b> leaves appressed to moderately secund or crispate when dry, complanate or erect to imbricate when moist, broadly ovate to lanceolate, ± abruptly narrowed mid leaf, not plicate proximally (somewhat plicate in <i>A. longifolius</i>); margins plane, sometimes undulate or revolute, entire, papillose, crenulate, serrulate, or sometimes denticulate near apex; apex rounded, obtuse, acute, or narrowly acuminate; costa usually strong, sometimes obscured by laminal cells and ending before mid leaf, sometimes discreetly, asymmetrically 2-fid at end, abaxial costa cells smooth or papillose; laminal cells hexagonal, obscure to irregular, small, papillae 1 or many, high, on both surfaces, walls thin; basal cells sometimes oblong, pellucid, smooth, walls incrassate. <b>Perichaetial</b> leaves well differentiated. <b>Seta</b> to 2.2 cm. <b>Capsule</b> symmetric; stomata sometimes present; peristome reduced (well developed in <i>A. rostratus</i>); exostome teeth white to pale brown, densely papillose, occasionally cross striolate, sometimes slightly trabeculate; endostome sometimes very reduced or absent (sect. Haplohymenium), basal membrane 2–7 cells high, segments keeled to linear and reduced or absent. <b>Calyptra</b> smooth to papillose or hirsute (sect. Haplohymenium). <b>Spores</b> 9–20(–23) µm.</span><!--

|discussion=<p>Species 16 (8 in the flora).</p><!--
--><p><i>Anomodon viticulosus</i> grows mostly on shaded calcareous outcrops, but the other species are found on tree trunks, including their base, logs, or sometimes soil or rock. <i>Anomodon attenuatus</i>, <i>A. minor</i>, and <i>A. rostratus</i> may grow on the same tree, with <i>A. rugelii</i> sometimes joining them in submontane regions. Although <i>A. tristis</i> may be found growing with the above species, it usually forms much thinner, more delicate mats higher on the tree. In North America, at least two species (<i>A. attenuatus</i> and <i>A. rostratus</i>) fruit profusely; <i>A. minor</i> and <i>A. rugelii</i> fruit less abundantly and perhaps less frequently, while sporophytes of <i>A. viticulosus</i> are extremely rare in North America (only one fertile specimen of <i>A. viticulosus</i> seen, none of <i>A. tristis</i>).</p><!--
--><p>Haplohymenium was created to accommodate plants that resemble <i>Anomodon</i> but are more slender and have a papillose calyptra with long, hyaline scattered hairs. Segregating Haplohymenium would make the rest of <i>Anomodon</i> paraphyletic, as Haplohymenium is a sister group of <i>A. minor</i>, <i>A. rugelii</i>, and <i>A. viticulosus</i>, all of which are part of subg. <i>Anomodon</i> (Í. Granzow-de la Cerda 1997); these taxa are more distantly related to subg. Pseudoanomodon (Limpricht) Ochyra, to which <i>A. attenuatus</i> and <i>A. rostratus</i> belong.</p>
