--><span class="statement" id="st-undefined" data-properties=""><b>Plants </b>to 85 × 5 mm. <b>Stem</b> mostly branched; axillary hyaline nodules absent; central strand present. <b>Leaves</b> as many as 60 pairs, somewhat undulate, oblong to lanceolate, acute, occasionally obtuse, to 3.5 × 1.2 mm; dorsal lamina rounded or narrowed proximally, ending at insertion, not decurrent; vaginant laminae 1/2–3/5 the leaf length, ± equal, minor lamina ending on or near margin; margin crenulate to regularly serrulate but irregularly serrate distally, elimbate; costa ending 2–3 cells before apex to percurrent, taxifolius-type; laminal cells usually 1-stratose, infrequently and irregularly 2-stratose in the dorsal and ventral laminae, distinct, smooth, ± plane, firm-walled, irregularly quadrate to hexagonal, 10–20 µm, 1–5 marginal rows usually thinner with slightly thicker walls, forming a lighter marginal band, juxtacostal cells larger, mostly oblong and pellucid; vaginant laminal cells somewhat larger. <b>Sexual</b> condition dioicous (?); perigonia not seen; perichaetia on short axillary branches, generally confined to proximal half of stems. <b>Sporophyte</b> 1 per perichetium. <b>Seta</b> to 25 mm. <b>Capsule</b> theca mostly ± inclined, ± arcuate, bilaterally symmetric, to 1.5 mm; peristome taxifolius-type; operculum to 1.5 mm. <b>Calyptra</b> cucullate, smooth, to 2.5 mm. <b>Spores</b> 13–22 µm.</span><!--

|discussion=<p>The usually 1-stratose, distinct, smooth, plane laminal cells, lighter band of marginal laminal cells, and short perichaetial stems in the axils of proximal leaves distinguish <i>Fissidens adianthoides</i>. The species, nevertheless, can be confused with <i>F. osmundioides</i>, which has similar laminal cells without a marginal band of lighter cells and a serrate leaf apex, but which differs in having terminal perichaetia and papillose rhizoids. <i>Fissidens dubius</i>, which also has short perichaetial stems in the axils of proximal leaves and often a lighter band of marginal laminal cells, differs from <i>F. adianthoides</i> in its smaller and rather obscure laminal cells that are consistently irregularly 2-stratose. <i>Fissidens adianthoides</i> and <i>F. dubius</i> (as F. cristatus), according to cytological evidence presented by L. E. Anderson and V. S. Bryan (1956), are distantly related.</p>
