--><span class="statement" id="st-undefined" data-properties=""><b>Plants </b>dark green to tan. <b>Stems</b> to 1.5 cm, central strand present. <b>Stem</b> leaves appressed and incurved when dry, patent to spreading-recurved and not keeled when moist, monomorphic, long-lanceolate, grooved adaxially along the costa, especially near leaf apex, 2–3 mm, base scarcely differentiated or short-oblong, margins narrowly recurved in proximal 1/3–1/2 of leaf, often broadly crenate (ca. 8–10 cells across), sinuose or weakly notched in distal 2/3–3/4 of leaf, apex narrowly acute or narrowly blunt and long-acuminate, somewhat fragile; costa percurrent or short-excurrent, not strongly spurred, not much widened or tapering, lacking an adaxial pad of cells, adaxial costal cells quadrate, ca. 4 cells wide at mid leaf, guide cells in 2 layers; basal laminal cells very weakly differentiated medially, walls thin to weakly thickened, quadrate to short-rectangular, not perforated; distal laminal cells 7–9 µm wide, 1:1, nearly smooth or papillae simple or 2-fid, 2–3 per lumen, lumens rounded-quadrate, walls thin or evenly thickened, weakly convex on both sides of lamina, distal 2/3–3/4 of the leaf margins 2-stratose with 1–2 rows of cells similar to the medial cells of the lamina. <b>Specialized</b> asexual reproduction apparently by fragile leaves. <b>Sexual</b> condition apparently dioicous; perigonia not seen; perichaetial leaves little different from the cauline or with wider bases. <b>Seta</b> 0.8–1.2 cm. <b>Capsule</b> 2–2.4 mm; peristome teeth 32, linear, weakly twisted or to 1/2 times, ca. 700–1000 µm. <b>Spores</b> 8–10(–13) µm. <b>Distal</b> laminal KOH reaction yellow-red.</span><!--

|discussion=<p><i>Didymodon eckeliae</i> is an uncommon species known from a few collections in southern and central California, and very recently in coastal British Columbia. F. Puche has collected it in Spain (Alicante, Font Rojas). It is closely related to <i>D. vinealis</i>, sharing the weakly differentiated leaf base, transverse section of the costa deeply convex, and the presence of a short, deep groove with the appearance of a long-elliptical window on the adaxial surface of the costa near the apex, but is immediately distinguished by distal leaf margins 2-stratose in a narrow band extending to the broadened base and often scalloped to weakly notched, at least in leaves of sterile plants. <i>Didymodon vinealis</i> may occasionally have distal leaf margins 2-stratose in small patches, but never evenly so (though sometimes, apparently, completely 2-stratose in distal portion of leaf); <i>D. nicholsonii</i> has a much broader, long-ovate leaf outline. <i>Didymodon</i> sinuosus (Mitten) Delongne of Europe is similar but its immature leaves have denticulate apices, and the distal marginal leaf cells are minutely crenulate (as in <i>Trichostomum tenuirostre</i>) and not 2-stratose.</p>
