--><span class="statement" id="st-undefined" data-properties=""><b>Plants </b>to 120 × 6 mm. <b>Stem</b> usually profusely branched; axillary hyaline nodules absent; central strand absent. <b>Leaves</b> in numerous pairs, lanceolate to linear-lanceolate, acute, to 6.5 × 0.7 mm; dorsal lamina narrowed proximally, usually ending before insertion; vaginant laminae 1/4–1/2 leaf length, acute, unequal in most leaves, minor lamina rounded above, attached on or near costa, ± equal on proximal part of stem, minor lamina ending near leaf margin; margin ± entire, elimbate or limbate in the proximal 2/3 or less of vaginant laminae; costa ending 5–15 cells before apex, bryoides-type; laminal cells 1-stratose, distinct, smooth, slightly bulging, ± firm-walled, quadrate to oblong to hexagonal, 10–15 × 9–11 µm. <b>Sexual</b> condition cladautoicous; perigonia on elongate, axillary branches; perichaetia terminal on mains stems and elongate, axillary branches. <b>Sporophytes</b> 1–2 per perichaetium. <b>Seta</b> 0.7–1.5 mm, often bent at the vaginula. <b>Capsule</b> theca erect, radially symmetric, 0.4–0.8 mm; peristome anomalous, teeth variable, undivided and often fenestrate to divided 2/3 their length, even in same capsule, nearly smooth to papillose proximally, filaments with straight or spiral thickenings or striations; operculum 0.4–0.6 mm. <b>Calyptra</b> not seen. <b>Spores</b> 14–32 µm.</span><!--

|discussion=<p><i>Fissidens hallianus</i>, named for Elihu Hall, has been confused with <i>F. fontanus</i>; they can be found growing together and both have similar vaginant laminae, although in <i>F. hallianus</i> there can be a weak limbidiuim on the proximal margin. Moreover, the costa is longer in <i>F. hallianus</i> than in <i>F. fontanus</i>. The sporophytes of <i>F. hallianus</i> are terminal, the number per perichaetium usually fewer than in <i>F. fontanus</i>, the seta is longer, relative to the length of the capsule, and the peristome teeth are complete. Sexual reproduction appears to be dependent on seasonal exposure.</p>
