--><span class="statement" id="st-undefined" data-properties=""><b>Plants </b>small, in dense cushions, sometimes turfs, or rarely gregarious, pale green-silver, pinkish, or yellow-silver. <b>Stems</b> 0.4–2 cm, sometimes julaceous, strongly branching by subfloral innovations; rhizoids many, micronemata and macronemata present on stems. <b>Leaves</b> imbricate when dry, erect to erect-spreading when moist, broadly ovate to spathulate, somewhat concave, 0.2–2 mm; base not decurrent; margins recurved or sometimes plane proximally, plane distally, serrulate to distinctly serrate near apex, 1-stratose, limbidium present or absent; apex broadly rounded to acute; costa long-excurrent, sometimes percurrent in proximal leaves, awn hyaline, denticulate to spinose, guide cells present; alar cells usually distinct in quadrate groups or sometimes transversely elongate in small groups; laminal areolation heterogeneous; proximal laminal cells usually quadrate to short-rectangular, 1–2:1; medial and distal cells hexagonal, rhomboidal, or almost vermicular, 3–6:1, walls thin to thick, not pitted. <b>Specialized</b> asexual reproduction absent. <b>Sexual</b> condition dioicous; perigonia and perichaetia terminal, leaves same size as vegetative leaves or usually larger, not forming rosette, inner leaves little differentiated. [Seta usually single, straight to somewhat twisted. <b>Capsule</b> erect, oblong or cylindric, 2–4 mm; hypophysis inconspicuous to well differentiated; operculum weakly convex, short-conic, not rostrate; peristome diplolepidous-alternate; exostome pale yellow or tan, sometimes reddish, teeth slender lanceolate; endostome separate or rarely adherent to exostome, basal membrane low, segments absent, cilia absent. <b>Spores</b> shed singly, not as tetrads, 17–25 µm, finely papillose, pale yellow-tan or brown].</span><!--

--><p><i>Leptostomopsis</i> is a distinctive genus superficially similar to Leptostomum. Recent molecular work suggests that the genus is basal to the remainder of Bryaceae. The genus was originally included in the polyphyletic <i>Brachymenium</i>. Although molecular work indicates that the genus should be placed in Bryaceae, morphologically it is close to Leptostomum and could be placed in Leptostomataceae. Plants of <i>Leptostomopsis</i> have reddish brown to yellow setae. The exostome teeth are not trabeculate.</p>
