Flora of North America species comparison

leaves generally larger than branch leaves, 1.3– 1.8 × 0.8–1 mm;

elliptic to lingulate-spatulate, widest above middle, hyaline cells nonseptate.

leaves lingulate, 1.3–1.6 mm, apex broadly rounded or pointed and notched (sometimes denticulate), border strong and broadened at base (more than 0.25 width);

hyaline cells short sinuoid-rhombic, mostly efibrillose, 0–1(–2)-septate.

long-cylindrical, branch leaves terete to sometimes distinctly squarrose in shade forms.

long and slender, never 5-ranked.

1–1.4 mm, ovate to ovate-lanceolate, gradually narrowed to an involute tip, hyaline cells somewhat bulging on concave surface and nearly plane on convex surface, with 4–8 large, elliptic, unringed pores per cell on convex surface and 1–4 irregularly rounded pores per cell on concave surface, internal commissural walls smooth to rather strongly papillose, chlorophyllous cells ovate-triangular with the widest part at or close to the convex surface.

ovate-lanceolate, 1.3–1.6 mm, concave, straight, apex strongly involute;

hyaline cells on convex surface with numerous round to elliptic pores along the commissures, grading from small round pores near the apex to large elliptic pores at the base, concave surface usually with large round pores throughout, but sometimes restricted to proximal portions of leaf.

dioicous.

dioicous, but some specimens apparently monoicous.

21–26 µm;

proximal and distal surfaces smooth, papillae indistinct;

proximal laesura 0.5–0.6 spore radius.

18–33 µm, coarsely papillose on both surfaces;

proximal laesura more than 0.5 spore radius.

fascicles typically with 3 spreading (sometimes 2) and 2 pendent branches.;

branch stems with single layer of cortical cells.

fascicles with 2 spreading and 1–2 pendent branches.
