--><span class="statement" id="st-undefined" data-properties=""><b>Leaves </b>ovate to lingulate, apex broadly acute to rounded, apiculate or mucronate, margins revolute or occasionally plane, often bordered proximally with rectangular cells usually hidden in the revolute margins; costa percurrent or ending in apiculus or short mucro, with an adaxial pad of swollen cells similar to those of the lamina, distally broad, (4–)6(–8) cells across adaxial surface; distal laminal cells subquadrate, 9–13(–18) µm wide, µm, 1:1; strongly papillose. <b>Sexual</b> condition autoicous. <b>Sporophytes</b> exerted. <b>Seta</b> 0.6–1.2 cm. <b>Capsule</b> stegocarpic, not systylius, cylindric to ellipsoidal, erect and nearly straight, urn 0.9–1.5 mm; peristome commonly 210–390 µm, teeth of 32 filaments, weakly twisted, occasionally rudimentary, basal membrane 40–50 µm; operculum 0.5–0.7 mm. <b>Spores</b> 15–18 µm, broadly ellipsoidal, nearly smooth.</span><!--

|discussion=<p><i>Tortula atrovirens</i> has a massive pad of bulging cells covering the costa, and may be mistaken for a <i>Crossidium</i>, which, however, has a ventral pad of filaments. It is somewhat similar to <i>T. obtusifolia</i>, which also has weakly differentiated, smooth, somewhat elongate marginal cells, but that species of more mesic climates and more northern latitudes has spatulate leaves lacking an adaxial pad.</p>
