--><span class="statement" id="st-undefined" data-properties=""><b>Plants </b>small, green or yellow-green, often with reddish tinge. <b>Stems</b> 0.5–1(–2) cm; rhizoids yellow-red, brown, or red-brown. <b>Leaves</b> loosely set, broadly lanceolate to narrowly ovate, weakly concave, 0.4–1.5(–2) mm; base not decurrent; margins plane to revolute proximally, serrulate distally, limbidium absent; apex acute to acuminate; costa short- to long-excurrent, awn slender, yellow to red; alar cells similar to adjacent juxtacostal cells; proximal laminal cells abruptly quadrate to occasionally short-rectangular, 1–2:1; medial and distal cells 40–60 × 10–12(–14) µm, 3–5:1. <b>Specialized</b> asexual reproduction by rhizoidal tubers, on long rhizoids in soil, red to red-brown, spheric, 120–180 µm, cells 20–40 µm, smooth. <b>Sexual</b> condition dioicous. <b>Capsule</b> inclined or nutant, 2–3 mm.</span><!--

|discussion=<p><i>Gemmabryum radiculosum</i> is distinguished by the relatively large, reddish, spheric tubers with smooth cells, similar in color to the rhizoids, long-excurrent costa, and preference for strongly calcareous substrates. <i>Gemmabryum subapiculatum</i> is similar, but with red tubers that are brighter than the rhizoids, a short-excurrent costa, and a preference for acidic substrates.</p>
