pink, superficial cortical cells aporose.;

stem leaves narrowly triangular to lingulate- triangular, 1.2–1.6 × 0.6–0.8 mm, length: width ratio ca. 2:1, apex apiculate, border strong and moderately broadened basally;

hyaline cells narrowly rhomboid and 1 to occasionally 2 septate, often fibrillose apically.

leaves triangular-lingulate to lingulate, 0.7–1.3 mm, appressed to stem, apex obtuse to broadly obtuse and erose to somewhat lacerate, hyaline cells efibrillose and nonseptate.

not 5-ranked.

curved, unranked to less commonly (in wet-grown forms) 5-ranked, leaves not much elongate at distal end.

1.3–1.5 × 0.5–0.55 mm, ovate-lanceolate, concave, straight, apex involute;

hyaline cells on convex surface with numerous round to elliptic pores along the commissures, grading from large elliptical pores at the base to moderate-sized round pores at the apex, concave surface with a few large round pores scattered throughout.

ovate-lanceolate to broadly ovate-lanceolate, 1.5–2.5 mm, strongly undulate and moderately recurved when dry, straight;

margin entire;

greater than hyaline cells on convex surface with 1–2 pores per cell at cell apex, on concave surface with round wall thinnings in the cell ends and angles; chlorophyllous cells triangular in transverse section and typically just slightly exposed on the concave surface.
