--><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 Tortula porteri by Ced. L. Porter (1937) from Wyoming is doubtful. This species is quite like Hennediella 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 T. obtusifolia by the more acute leaves with plane margins.</p>
