--><span class="statement" id="st-undefined" data-properties=""><b>Plants </b>small, green, brown, or red-green. <b>Stems</b> 0.5–2 cm, distinctly singly rosulate, innovations elongate, evenly foliate. <b>Leaves</b> of fertile rosettes and innovations differentiated; rosette leaves irregularly twisted to contorted when dry, erect-spreading when moist, broadly ovate to obovate, flat, 1–2.5 mm; base not decurrent; margins recurved to mid leaf, entire or weakly serrulate distally, limbidium absent or weak, of 1 row of cells; apex acute; costa not reaching apex to excurrent, awn pigmented or hyaline, slender, irregularly twisted when dry; proximal laminal cells long-rectangular; medial and distal cells long-rhomboidal, 12–20 µm wide, 3–5:1, walls thin, porose; innovation leaves red-brown, somewhat twisted to weakly imbricate when dry, broadly lanceolate to ovate, concave, 0.5–1.5 mm, awn present, short, pigmented to sometimes hyaline. <b>Specialized</b> asexual reproduction rarely by gemmae in distal leaf axils, brown, finely papillose, and rhizoidal tubers, usually on long rhizoids away from stem base, orange-red to red, brighter than rhizoids, (60–)100–200 µm, smooth or almost so. <b>Sexual</b> condition dioicous. <b>Capsule</b> inclined to nutant, brown to red-brown, cylindric, 2–5 mm.</span><!--

|discussion=<p><i>Rosulabryum gemmascens</i> is closely related to <i>R. capillare</i>, but differs in the unusual evenly foliate red-brown innovations, leaves not spirally twisted around the stem, very weak or absent limbidium, and almost entire distal margins. The species is endemic to coastal areas, and is especially common in Mediterranean climate areas of California.</p>
