Flora of North America species comparison

leaves generally longer than branch leaves, 1.1–1.7 mm, lingulate to lingulate-spathulate, hyaline cells mostly non-septate.

leaves lingulate-spatulate, large, 1.3–1.6 mm; appressed to stem;

apex very broad and lacerate;

hyaline cells efibrillose and aporose, often septate.

terete.

strongly 5-ranked and straight.

1–1.4 mm, broadly ovate, with a narrow involute tip;

hyaline cells only slightly bulging on either surface, in proximal half of leaf aporose on convex surface and with large faint pores on concave surface;

internal commissural walls distinctly papillose; chlorophyllous cells elliptical to elliptical-triangular in transverse section, enclosed on both surfaces with the widest part in the leaf middle.

ovate-lanceolate, 1.5–3 mm; straight to slightly subsecund; imbricate to somewhat reflexed and not undulate;

margins entire;

hyaline cells long and narrow, length to width ca. 10:1 on convex surface with 1 or more small pores in the cell ends and angles and often with numerous pseudopores along the margins, on concave surface with large round wall thinnings on the cell ends and angles; chlorophyllous cells triangular to trapezoidal in transverse section, apex often exposed on concave surface.

dioicous.

monoicous or dioicous.

ca. 31 µm, ornamented by small somewhat amalgamated granulae.

22–34 µm;

both surfaces smooth, apparent ridged border on proximal surface;

proximal laesura more than 0.5 spore radius.

fascicles of 2 spreading and 1–2 hanging branches.;

branch stems with 1–2 layers of cortical cells.

fascicles with 2 spreading and 2 pendent branches, leaves not much elongated at distal end.;

branch stems green, with cortex enlarged with retort cells.
