Characteristics

Plants caespitose, yellow-green; terricolous. Stems 2-10 mm high, branching by subperichaetial innovations; in section with central strand of collapsed cells, inner cortical cells large, in 2 rows, outer cortical cells smaller, in 1-2 rows. Leaves bract-like below, larger above, erect to spreading; ovate-lanceolate to lanceolate, acuminate, 0.9-1.2 mm long, ventral surface flat to channelled; base often clasping; margins plane to recurved above, entire; lamina bistratose juxtacostally. Costa percurrent; in section crescent-shaped, ventral surface flat, cells undifferentiated, incrassate. Laminal cells irregular, trapezoidal, short-rectangular, quadrate and short-rhomboidal; basal cells irregularly short-rectangular to quadrate. Perichaetia terminal. Leaves erect, loosely secund, concave, narrowly acuminate to subulate above an ovate to oblong base, 1.2-1.8 mm long; margins plane to recurved above, entire to crenulate; lamina bistratose juxtacostally. Costa percurrent to excurrent; in section crescent-shaped, ventral surface flat, cells undifferentiated, incrassate. Laminal cells irregular, rectangular to trapezoidal or rhomboidal, 30-60 µm long, larger below; basal cells irregularly rectangular to rhomboidal, thin-walled, hyaline. Spores 12-28 per capsule, 132-167 µm, smooth to granulose, yellow.
