Flora of North America species comparison

pale green to straw-colored;

superficial cortical with a large round pore in distal portion of cell free from cell wall.

pale green to light brown, rarely dark brown;

superficial cortex of 2–3 layers of enlarged, thin-walled cells.

not 5-ranked, quite terete, long, and slender Branch fascicles with 1– 2 spreading and 1–2 pendent branches.

somewhat curved, leaves spreading.

spatulate to broad-spatulate, 0.8–1.5(–2) mm, strongly lacerate across the broad apex and often part way down the margins, border scarcely to strongly broadened at base (0.25 width of base or less);

hyaline cells rhomboid, efibrillose and often 1–2-septate.

triangular-lingulate to lingulate, 0.7–1.4 mm;

apex rounded-obtuse and weakly denticulate;

hyaline cells nonseptate, mostly efibrillose, and, if porose, with more pores per cell on the concave surface (3–6) than on the convex surface (0–2).

ovate to ovate-lanceolate; 1.1–1.5(–2) mm, slightly concave, straight;

apex involute;

margins entire;

hyaline cells on convex surface with numerous pores along the commissures grading from small pores near leaf apex to large pores at base, concave surface with large round pores at leaf apex and along margins.

ovate to ovate-lanceolate, 1.2–2 mm;

subsecund;

hyaline cells with numerous tiny pores in a continuous line along the commissures on the convex surface, no or scattered pores on the concave surface.

with 2–3 spreading and 2–3(4) pendent branches.

often monoicous.

dioicous.

exserted, with scattered pseudo-stomata.

20–27 µm, finely papillose on both surfaces;

proximal laesura less than 0.5 spore radius.

22–28 µm;

papillose on both surfaces;

proximal laesurae more than 0.5 spore radius.
