Flora of North America species comparison

leaves triangular-lingulate to lingulate, 1.1–1.4 mm, apex broad-rounded to narrowly truncate, border very broad at base (more than 0.3 width);

hyaline cells efibrillose, rhombic, mostly 1-septate but can be non-septate.

leaves narrowly to broadly lingulate or sometimes lingulate-spatulate, (1.1–)1.2–1.4(–1.6) mm;

apex broadly obtuse to obtuse-truncate and more or less fimbriate-lacerately resorbed, border in distal half narrow and often indistinct, in proximal half widened and filling up 1/3–1/2(–2/3) of the breadth at the base;

hyaline cells broadly S-shaped to rhombic S-shaped, predominantly nonseptate but a few cells are 1–3-septate;

efibrillose.

long and tapering, usually strongly 5-ranked.

unranked, terete.

ovate-lanceolate, 0.9–1.4 mm, concave, straight, apex involute;

hyaline cells on convex surface with very small ringed pores (less than 0.25 cell width) along commissures near apex, changing abruptly to large elliptical pores (0.4 cell width or more) basally, concave surface with large round pores in proximal margins and leaf base.

broadly lanceolate to ovate-lanceolate, (1.1–)1.4–1.8(–2.1) mm, slightly concave, straight to slightly subsecund;

apex involute;

border entire;

hyaline cells on convex surface with (5–)8–10(–12) semicircular to elliptical, ringed pores along the commissures, concave surface aporose or infrequently with 1–2 pores per cell in the distal portion of the cell, more numerous along leaf margins.

dioicous.

unknown.

17–26 µm, finely papillose on both surfaces;

proximal laesura less than 0.5 spore radius.
