Characteristics

Plants caespitose, yellow or yellow-green; terricolous. Stems 1-5 mm high, branching by subperichaetial innovations; in section with central strand of collapsed cells, inner cortical cells thin-walled, large, in single row, outer cortical cells smaller, in 1-2 rows. Leaves bract-like below, larger above, erect to erect-spreading, ovate-lanceolate to lanceolate, acuminate, 0.9-1.1 mm long; margins plane, entire. Costa excurrent or forming hair-point; in section round, cells undifferentiated, incrassate or stereids. Laminal cells rhomboidal to fusiform, incrassate; basal cells short-rectangular to quadrate; lower marginal cells rectangular to quadrate. Perichaetia terminal. Leaves erect to erect-spreading, occasionally secund; ovate-lanceolate to oblong-lanceolate, acuminate, 0.8-1.4 mm long; margins entire, plane to faintly recurved above. Costa excurrent as hair-point; in section round, surface cells incrassate or substereids, central cells sub-stereids to stereids. Laminal cells fusiform, shorter above and along margins, 48-88 µm long, walls 3-7 µm wide, lumen 5-9 µm wide; basal cells rectangular, thin-walled, basal marginal cells hyaline. Spores 10-17 per capsule, irregularly rounded, 88-202 µm, smooth to granulose, yellow.
