General Description
Plants: Pleurocarpous (Vitt 1988), threadlike (FNA 2014), small and in mats, light- to yellow-green. Stems about 10 mm long, frequently branched, the shoot with its appressed leaves resembling a slightly loose catkin (Lawton 1971).

Leaves: Stem leaves upright to spreading, loosely overlapping, round to broadly ovate, 0.3-0.4 mm long (FNA 2014), mostly longer than wide, greatly concave, acuminate to apiculate (Lawton 1971); the apiculous often recurved (FNA 2014); the base rounded; margins flat or incurved, smooth to serrulate from protruding cell ends; costa lacking or weak (Lawton 1971).

Leaf Cells: Laminal cells rhomboidal; distal laminal cells with one tiny papilla per cell on the abaxial (outer-facing) surface; alar cells not distinctive (FNA 2014).
