--><span class="statement" id="st-undefined" data-properties=""><b>Plants </b>medium-sized to large, in moderately dense mats, light green, yellow-green, or whitish stramineous. <b>Stems</b> to 7 cm, creeping, terete-foliate, irregularly pinnate, branches to 8 mm, straight to slightly curved, terete-foliate. <b>Stem</b> leaves erect, loosely appressed, loosely imbricate, narrowly ovate-triangular or ovate-lanceolate, broadest at 1/9–1/7 leaf length, sometimes almost at costa insertion, concave, plicate, plicae usually parallel in falcate leaves, often shallow and uneven in straight leaves, giving some leaves a crumply appearance, 1.5–2.6 × 0.5–1.2 mm; base rounded, broadly short-decurrent; margins partly plane, recurved in many places, serrulate to serrate in acumen, occasionally almost entire, variable within one shoot; apex gradually tapered or acuminate; costa to 40–70% leaf length, moderately strong, small terminal tooth sometimes present; alar cells subquadrate or short-rectangular, same size as or smaller than basal cells, 15–25 × 11–13 µm, walls thick, region ± clearly delimited, 4–9 × 4–7 cells; laminal cells linear, (30–)60–100(–110) × 6–9 µm; basal cells to 20–40 × 10–15 µm, region in 1–3 rows, not markedly different from more distal cells. <b>Branch</b> leaves often falcate-secund; alar region conspicuous, pellucid, triangular. <b>Sexual</b> condition autoicous. <b>Seta</b> orange-brown to dark brown with age, 2–2.5 cm, rough or occasionally smooth. <b>Capsule</b> inclined to horizontal, dark brown, elongate, curved, 2 mm; annulus separating by fragments; operculum conic. <b>Spores</b> 15–19 µm.</span><!--

|discussion=<p>A. J. Grout (1928–1940, vol. 3) and H. A. Crum and L. E. Anderson (1981) expressed some doubts on the status of <i>Brachythecium campestre</i> and its clear differentiation from <i>B. salebrosum</i>. However, <i>B. salebrosum</i> seems absent or at least rare in eastern North America (except probably the more northern regions of eastern Canada). The vast majority of collections referred to <i>B. salebrosum</i> in eastern North America belong to <i>B. acutum</i>, <i>B. campestre</i>, <i>B. rotaeanum</i>, and other species. There are some differences between European and American <i>B. campestre</i>; if further studies provide additional evidence for their separation, then the American populations should be called B. leucoglaucum; for typification of this name and discussion on this species, see M. S. Ignatov et al. (2008). The diagnostic characters of <i>B. campestre</i> include the usually light green to whitish color, ovate-lanceolate leaves that are rather crumply plicate when optimally developed, alar cells in small to large groups of rather small and subquadrate cells, and, usually, a minutely rough seta.</p>
