--><span class="statement" id="st-undefined" data-properties=""><b>Plants </b>small, in loose to dense tufts, green usually only when very young, pale yellow or brownish yellow with age. <b>Stems</b> 2–4 cm, creeping to ascending, in dense tufts erect, terete-foliate, julaceous or subjulaceous, irregularly pinnate, branches to 4 mm, terete-foliate. <b>Stem</b> leaves appressed proximally, closely imbricate, straight to falcate, ovate to broadly ovate-lanceolate, not to rarely moderately plicate, 0.5–1(–1.5) × 0.2–0.5(–0.7) mm; margins plane or recurved proximally, coarsely serrate almost to base; apex abruptly or rarely gradually short-acuminate, acumen somewhat spreading to reflexed, often homomallous to falcate-secund; costa to 40–70% leaf length, occasionally almost absent, terminal spine absent; alar cells subquadrate, 8–20 × 9–11 µm, region small, of 10 × 4–6 cells, distinctly delimited; laminal cells elongate to linear, 25–60 × 4–7 µm; basal cells almost undifferentiated. <b>Seta</b> reddish orange, 0.6–1.4 cm, slightly roughened, sometimes almost smooth except basal 1/4. <b>Capsule</b> slightly inclined to horizontal, reddish orange, ovate to subcylindric, 1–1.8 mm; endostome basal membrane 1/3 endostome length or longer, cilia as long as segments. <b>Spores</b> 9–12 µm.</span><!--

|discussion=<p>Although stems of <i>Brachytheciastrum collinum</i> are usually julaceous, the leaves are sometimes well spaced, making some populations difficult to distinguish from <i>Brachythecium bolanderi</i>. In this case, the rather extensive alar group and the autoicous sexual condition of <i>B. collinum</i> are helpful, as well as the more abruptly short-acuminate leaves. Some authors distinguish <i>B. collinum</i> and <i>B. fendleri</i> by the non-plicate leaves of the former. However, some collections, for example New Mexico, Santa Fe County, Buck 39717, have plicate leaves, while leaves of <i>B. fendleri</i> are usually smooth.</p>
