    Morphology

    Plants loosely caespitose, yellow to yellow-green; terricolous. Stems 1-4 mm high, simple or branching by subperichaetial innovations; in section round, central strand of collapsed cells, cortical cells large, incrassate, outer 1-2 rows smaller. Leaves bractlike below, larger above, erect; ovate to ovate-lanceolate, 0.6-1.0 mm long; apex acute or apiculate; margins plane, entire to crenulate. Costa percurrent to apiculate; in section semi-circular or crescent-shaped, ventral surface flat, cells undifferentiated, substereids or stereids. Laminal cells irregular, short-rectangular to quadrate or trapezoidal; basal cells not differentiated. Perichaetia terminal. Leaves erect to erect-spreading; ovate to oblong-ovate or elliptic, acuminate to subulate, 0.8-1.7 mm long; margins plane to weakly recurved above, irregularly crenulate, frequently hyaline above. Costa excurrent as hair-point; in section semi-circular or crescent-shaped, ventral surface flat, cells undifferentiated, substereids to stereids. Laminal cells irregular, rhomboidal to fusiform and trapezoidal, sometimes quadrate, 20-45 µm long, incrassate; basal cells irregularly rectangular, thin-walled, hyaline in marginal region. Spores 8-40 per capsule, irregularly rounded to polyhedral, 125-176 µm, smooth, pale yellow to yellow-orange.
