--><span class="statement" id="st-undefined" data-properties=""><b>Plants </b>2–10 mm, perennial, in dense turfs, yellow-green. <b>Stems</b> simple or usually branched by several sterile innovations, becoming prostrate with age. <b>Stem</b> leaves erect to erect-spreading, lanceolate to narrowly ovate-lanceolate, acuminate, 1–2.5 mm; costa percurrent or short-excurrent, sometimes somewhat subulate; laminal margins recurved, smooth or finely serrulate distally; median and distal laminal cells irregular in shape, mixed quadrate, trapezoidal, short-rectangular, short- to long-rhomboidal, 14–75 × 8–13 µm, proximal cells quadrate to short-rectangular, similar to median and distal cells; leaves of innovations similar to stem leaves, not much reduced proximally. <b>Perichaetial</b> leaves broadly ovate-lanceolate, narrowly acuminate to subulate, sometimes flexuose to secund, same size as stem leaves; costae short to long excurrent, hairpoint pellucid, sometimes finely spinose; laminal margins recurved, smooth to finely serrulate; distal and median laminal cells similar to stem leaves, proximal laminal cells lax, wider, rectangular, 2–4:1, 35–115 × 12–25 µm, sometimes somewhat hyaline. <b>Specialized</b> asexual gemmae absent. <b>Sexual</b> condition autoicous; antheridia terminating axillary leaf buds. <b>Capsule</b> terminal, 425–750 µm. <b>Spores</b> typically 28(4–60) per capsule, angular to irregularly polyhedral, 120–230 µm, smooth or finely granulose, yellow to orange-red.</span><!--

-->{{Treatment/Body
|phenology=Capsules mature early spring (Mar), more rarely in autumn or winter (Oct–Dec).
|habitat=Uncommon on moist to dry soil along roadsides, in fields, rarely on rock
|elevation=0-250 m
|distribution=Ill.;Md.;Okla.;N.C.;S.C.;Tex.;Va.;Mexico.
|discussion=<p><i>Archidium donnellii</i> usually can be distinguished from other species by irregular areolation in median and distal portions of lamina, proximal lamina cells not strongly differentiated, and sexuality autoicous. It tends to grow in drier habitats than do other species of the genus.</p>
