--><span class="statement" id="st-undefined" data-properties=""><b>Plants </b>2–20 mm, perennial, sometimes gregarious but mostly in dense short turfs, green to yellow-green. <b>Stems</b> variable, simple, with few innovations, or often short and multi-branched by numerous innovations from axils of stem leaves or exterior perichaetial leaves, often becoming prostrate with age, innovations fragile and often detached. <b>Stem</b> leaves erect to erect-spreading, lanceolate, triangular or ovate-lanceolate, narrowly acuminate to subulate, 0.5–2 mm, becoming reduced proximally; costa percurrent to distinctly excurrent in hairpoint; laminal margins plane, smooth or finely serrulate distally; median laminal cells rhomboidal to prosenchymatous, 4–8:1, 45–90 × 9–15 µm, somewhat shorter distally and along margin, proximal cells short-rectangular to rectangular, 2–4:1, 25–60 × 12–16 µm, short-rectangular to quadrate in alar region in 2–6 rows extending 6–15 cells along proximal lamina margin; leaves of innovations similar to distal stem leaves except smaller, often sharply reduced proximally. <b>Perichaetial</b> leaves variable in shape, ovate, oblong, ovate-lanceolate to lanceolate, larger, 1–2 mm, short- to long-acuminate; costa percurrent to long-excurrent, often forming pellucid hairpoint; laminal margins smooth, plane or rarely weakly recurved; median laminal cells rhomboidal, linear-rhomboidal to prosenchymatous, 4–8:1, 45–140 × 9–15 µm, shorter distally and along margin, proximal cells hyaline, lax, rectangular to rhomboidal, 4–6:1, 50–90 × 12–18 µm. <b>Specialized</b> asexual reproduction absent. <b>Sexual</b> condition autoicous, antheridia terminating axillary leaf buds. <b>Capsule</b> lateral, or both lateral and terminal, 270–600 µm. <b>Spores</b> typically 16(4–60) per capsule, rounded-triangular to polyhedral, 110–320 µm, pale yellow, smooth to papillose.</span><!--

|discussion=<p><i>Archidium ohioense</i> is the most widespread and variable species in the genus. J. A. Snider (1975) assigned many names to the synonymy of this species. In the United States, the plants vary from rather tall, lax, weakly branched forms with longer leaves in wet sites to short, strongly branched forms with shorter leaves in drier sites. The perichaetial position is also highly variable. Future work may show the species to consist of a series of closely similar species, as suggested by the rather anomalous and scattered world distribution. <i>Archidium ohioense</i> is most easily confused with <i>A. alternifolium</i> and <i>A. tenerrimum</i>, but can be distinguished from them by a combination of primarily lateral capsules, antheridia enclosed in leafy bracts, and sexuality autoicous.</p>
