--><span class="statement" id="st-undefined" data-properties=""><b>Plants </b>minute, 1–3(–5) mm, ephemeral, solitary or gregarious, yellow-green to pale green. <b>Stems</b> mostly simple or sometimes with 2–4 short fertile branches from distal stem leaves, sterile innovations absent. <b>Stem</b> leaves similar to perichaetial leaves but usually smaller, reduced proximally to bracts, erect-spreading or loosely spreading, triangular to linear-lanceolate, acute or broadly obtuse; costa weak, not reaching apex or occasionally absent; laminal margins plane, smooth; median and distal laminal cells of distal stem leaves rectangular, 3:1, 35–45 × 15–20 µm, slightly broader and laxer proximally but not conspicuously different. <b>Perichaetial</b> leaves erect-spreading or loosely spreading, triangular to linear-lanceolate, acute or broadly obtuse; costa weak, not reaching apex or occasionally absent; laminal margins plane, smooth; median and distal laminal cells elongate-rectangular to rhomboidal, 3–5:1, 50–130 × 13–24 µm, distally somewhat smaller, proximal cells rectangular, wider than median and distal cells. <b>Specialized</b> asexual reproduction absent. <b>Sexual</b> condition synoicous, antheridia and archegonia intermixed. <b>Capsule</b> terminal, 350–650 µm. <b>Spores</b> typically 32(16–48) per capsule, 115–175 µm, smooth or papillose, pale green to yellow or yellow-brown.</span><!--

|discussion=<p><i>Archidium minus</i> is easily distinguished from other species of the genus by its small size, synoicous sexuality, and the bluntly acute, mostly lanceolate leaves with weak costa. Unlike the other species, it is ephemeral and does not produce the sterile prostrate innovations that give rise to next season’s fertile shoots. It is not closely related to any other <i>Archidium</i> species in North America.</p>
