--><span class="statement" id="st-undefined" data-properties=""><b>Leaves </b>broadly ovate-lanceolate, apex broadly acute or occasionally rounded, not or weakly apiculate, margins plane, always distinctly bordered nearly throughout with 2–4 rows of narrower, thicker-walled, smooth or weakly papillose cells; costa percurrent or ending in an apiculus, lacking an adaxial pad of cells, distally of even thickness, 4(–6) cells across adaxial surface; distal laminal cells hexagonal or sometimes subquadrate, width 11–15 µm, 1:1; hollow-papillose medially. <b>Sexual</b> condition dioicous. <b>Sporophytes</b> exerted. <b>Seta</b> 0.5–0.8(–1) cm. <b>Capsule</b> stegocarpic, not systylius, cylindric, erect and nearly straight, urn 1.1–1.5(–1.8) mm; peristome 200–350 µm, weakly twisted, teeth of 32 rather short filaments variously anastomosing proximally, basal membrane 60–100 µm; operculum 0.4–0.8 mm. <b>Spores</b> 8–10 µm, spheric, finely papillose or nearly smooth.</span><!--

|discussion=<p>A report of <i>Tortula porteri</i> by Ced. L. Porter (1937) from Wyoming is doubtful. This species is quite like <i>Hennediella</i> in leaf traits such as plane margins, flattened superficial laminal cell walls, and border of elongate, thick-walled cells, but is yellow in KOH solution and lacks marginal teeth. The two genera intergrade somewhat and a less arbitrary distinction than simple emphasis on KOH color reaction awaits more study. This species is distinguished from <i>T. obtusifolia</i> by the more acute leaves with plane margins.</p>
