--><span class="statement" id="st-undefined" data-properties=""><b>Plants </b>light green to yellowish or brownish. <b>Stems</b> 4–9 cm, 2-pinnate, frondose; paraphyllia papillose usually at or near cell ends. <b>Stem</b> leaves ± incurved basally and wide-spreading apically when dry, spreading with reflexed apices when moist, broadly ovate, distinctly plicate, 1 mm; margins plane at least when removed from stem, rarely ± revolute proximally, papillose-serrulate, more strongly so in acumen; apex abruptly acuminate; costa nearly filling acumen but disappearing near apex; distal laminal cells rhombic to oblong-rhombic, to 24 × 8–10 µm. <b>Branch</b> leaves apical cell truncate, multipapillose. <b>Primary</b> branch leaves to 0.5 mm; costa shorter. <b>Secondary</b> branch leaves 0.2 mm; apex acute; costa 1/3–2/3 leaf length. <b>Perichaetial</b> leaves to 4.2 mm, margins denticulate, sometimes dentate or notched near base of acumen. <b>Seta</b> 2–4.2 cm. <b>Capsule</b> 2–3.5 mm; operculum 0.7–1 mm, long-conic or bluntly short-rostrate; endostome cilia in groups of 2 or 3. <b>Spores</b> 11–16 µm, smooth or nearly so.</span><!--

|discussion=<p>The specific epithet of <i>Thuidium recognitum</i> was applied by Hedwig because he recognized the many differences that separate the species from <i>T. delicatulum</i>: stem leaves that are shortly, broadly, and abruptly acuminate and plicate, with margins plane or nearly so; costa spreading out and nearly filling the acumen; stem leaf apices wide-spreading from an arched and incurved base; perichaetial leaves eciliate; paraphyllia papillose at or near cell ends; and operculum not or only shortly and bluntly rostrate. The secondary branch leaves of <i>T. recognitum</i> are erect-spreading when dry or moist and have rhombic distal laminal cells, 8–12 × 8–10 µm, that are thick-walled and stoutly 1-papillose with papillae somewhat curved.</p>
