Characteristics

Plants loosely caespitose, yellow to yellow-green; terricolous. Stems 3-5 mm high, branching by subperichaetial innovations; in section central strand present, inner cortical cells large, incrassate, in 1-3 rows, outer cortical cells smaller, incrassate, in 1-3 rows. Leaves bract-like below, larger above, erect-spreading to spreading, concave; ovate-lanceolate, acuminate, 0.9-1.2 mm long; margins plane to slightly recurved, entire. Costa percurrent to short-excurrent; in section semi-circular, ventral surface flat, cells incrassate or stereids dorsally, ventral cells larger. Laminal cells irregularly short-rectangular to quadrate or trapezoidal; basal cells not differentiated or slightly larger. Perichaetia terminal. Leaves erect to erect-spreading, frequently secund, concave; broadly ovate-lanceolate to oblong-ovate, acuminate to subulate, 1.4-2.0 mm long; base broadly ovate to oblong or concave; margins narrowly recurved above, entire. Costa percurrent to slightly excurrent, in section semi-circular, ventral surface flat, dorsal cells incrassate or stereids, ventral cells larger. Laminal cells irregularly rectangular to rhomboidal or trapezoidal, 40-80 µm long, larger below, basal cells irregularly rectangular, thin-walled, hyaline. Spores 20-40 per capsule, irregularly rounded triangular to tetrahedral, 149-85 µm, densely papillose, yellow to yellow-brown.
