Flora of North America species comparison

leaves broadly ovate, 1.5–2(2.5) mm; straight;

hyaline cells fibrillose and nearly aporose, with single small pores occasionally found in the distal cell ends on the concave surface.

leaves ovate-triangular to triangular, 1–1.6 mm; appressed to spreading;

apex acute to slightly obtuse;

hyaline cells often fibrillose and often 1-septate.

lacking or short and slender.

straight and unranked, in capitulum tapering at distal end to a point, leaves greatly elongated at distal end.

when present similar to stem leaves but smaller, 0.8–1.2 mm, hyaline cells fibrillose and mostly aporose, 1–6 irregularly round-shaped membrane gaps in some cells near apex on convex surface.

ovate-lanceolate to lanceolate, 2–3.5 mm; straight, undulate and slightly recurved when dry;

margin serrulate;

hyaline cells on convex surface with 0–1 small pores at cell apex on concave surface with round wall thinnings in cell angles (often indistinct or lacking); chlorophyllous cells trapezoidal in transverse section and exposed more broadly on the convex surface.

dioicous.

monoicous.

usually immersed in perichaetiale leaves, but may be slightly emergent, pseudostomata absent from capsule surface.

29–41 µm, coarsely papillose on both surfaces, indistinct raised sculpture on distal surface;

proximal laesura less than 0.5 spore radius.

26–40 µm; ± roughly to densely granulose.

fascicles none or 1 spreading branch.
