Plants small, 5–8 mm high, light-green, loosely gregarious or in turfs. Stems elongate, simple or forked; rhizoids dark-red, conspicuous. Leaves involute, erect-ascending and loosely secund when dry, straight and with involute margins when wet, narrowly linear to lanceolate above broader base, to 2.0–4.5 mm long, axillary hairs inconspicuous; costa smooth to papillose or remotely spinose abaxially, smooth to thickly spinose adaxially; cells of upper laminae pellucid, isodiametric to rectangular, smooth abaxially except toward margin where usually some laminal cells are papillose-spinose in abaxial intramarginal rows, but abaxial rows of spinose papillae are lacking on some leaves; margins of upper laminae narrowly bordered nearly all around with hyaline cells, border weak or lacking near leaf tip, often difficult to see in narrow leaves because of involution of leaf margins; margins of lower laminae with delicate hyaline cilia, the cilia to 70–90 µm long; cancellinae ending in acute angles distally. Gemmae inconspicuous, on adaxial surface of costa tip. Sporophytes unknown.
