--><span class="statement" id="st-undefined" data-properties=""><b>Plants </b>in open, occasionally compact tufts, olivaceous or brownish, sometimes with yellow or orange tones. <b>Stems</b> 1–3.5(–5) cm, central strand distinct. <b>Leaves</b> erect or slightly curved when dry, ovate-lanceolate, sharply keeled distally, 1.7–3.3 mm, 1-stratose with 2-stratose striae or patches or occasionally 2-stratose distally; margins recurved to well just before the apex, often less recurved to nearly plane on part of one side of leaf, usually denticulate near apex, usually 2-stratose or 3-stratose; apices acute; costa percurrent or excurrent as a denticulate, usually decurrent awn, abaxial surface often papillose; basal marginal cells quadrate or short-rectangular, transverse walls often somewhat thicker than longitudinal walls, often trigonous; distal laminal cells usually rounded or short-rectangular, 8–9 µm wide, weakly sinuose. <b>Sexual</b> condition autoicous. <b>Capsule</b> red-brown, sometimes orange-brown, elongate-cylindric to cylindric, 0.8–1.4 mm; exothecial cells mostly elongate, mixed with angular-isodiametric cells, walls unevenly thickened and somewhat curved, often trigonous; stomata absent or few; peristome patent to squarrose, sometimes twisted, 300–450 µm, red, densely to finely papillose, entire or strongly perforated. <b>Spores</b> 8–11 µm, granulose or verruculose.</span><!--

|discussion=<p><i>Schistidium crassipilum</i> is distinguished by its unevenly 2-stratose leaves, its elongate-cylindrical to cylindrical capsules, and the mostly elongate exothecial cells, with their cell walls unevenly thickened and somewhat curved. S. Flowers (1973) may have illustrated this species (as <i>Grimmia</i> apocarpa), although details of the exothecial cells that would confirm this are absent in his illustrations.</p>
