--><span class="statement" id="st-undefined" data-properties=""><b>Plants </b>3–10 mm, perennial, in dense short turfs, pale-green to yellow-green. <b>Stems</b> branched by several innovations from axils of stem leaves or outer perichaetial leaves, often becoming prostrate with age. <b>Stem</b> leaves erect-spreading, lanceolate to ovate-lanceolate, acuminate, 0.7–1.5 mm, becoming reduced proximally; costa percurrent to slightly excurrent; laminal margins smooth, weakly recurved; median and distal laminal cells rhomboidal to hexagonal, 3–4:1, 35–70 × 12–18 µm, proximal cells rectangular, 2–4:1, 40–70 × 18–24 µm, short-rectangular to quadrate in alar region in 2–6 rows extending 7–15 cells along proximal laminal margin; leaves of innovations similar to distal stem leaves except being smaller, gradually reduced proximally. <b>Perichaetial</b> leaves larger, 1.5–3 mm, elongate-triangular, lanceolate or ovate-lanceolate, gradually acuminate; costa percurrent to short-excurrent; laminal margins smooth, weakly recurved distally; median and distal laminal cells uniformly rhomboid to hexagonal, 3–7:1, 35–130 × 15–28 µm, proximal cells rectangular, 4–6:1, 70–140 × 15–28 µm, sometimes hyaline in alar region but cells not strongly differentiated. <b>Specialized</b> asexual reproduction absent. <b>Sexual</b> condition autoicous, antheridia terminating axillary leaf buds. <b>Capsule</b> terminal, 450-700 µm. <b>Spores</b> typically 20(8–36) per capsule, triangular to rounded-polyhedral, 140–250 µm, smooth to granulose, yellow.</span><!--

-->{{Treatment/Body
|phenology=Capsules mature early spring (Mar) or rarely late fall (Nov).
|habitat=Uncommon to rare on moist open sandy or loamy soil, along roadsides and in grassy often disturbed areas
|elevation=0-200 m
|distribution=Fla.;Ga.;Tex.;Mexico;South America.
|discussion=<p><i>Archidium hallii</i> can be distinguished from similar-looking forms of <i>A. tenerrimum</i> by autoicous sexuality and leafy bracts enclosing the antheridia.</p>
