erect to excurved, leafy, obscurely trigonous, slender.
erect or excurved, lax, leafy, slender to wiry.
spreading to ascending, shorter than culm, crowded toward culm base;
blades linear, proximally flat, 1–3 mm wide, gradually involute, apically trigonous, subulate.
overtopped by culm;
basal leaves spreading, twisted, distal longer, erect or ascending;
blades proximally flat, 1–3 mm wide, apex trigonous, subulate, tapering.
spikelet clusters 1–4, dense to open, mostly irregularly turbinate;
peduncles ascending, branches spreading to erect, ultimate branches with many spikelets; leafy bracts setaceoustipped, usually exceeding all clusters, or at least all but the distal.
spikelet clusters 1–4, proximalmost widely spaced, spikelets elongate, open, turbinate or compactlobed hemispheric;
branches erect to ascending; leafy bracts setaceous, exceeding proximal clusters, exceeded by distal clusters.
light redbrown or brown, broadly ellipsoid to lanceoloid, 3–4 mm, apex acute to acuminate;
fertile scales ovate to obovate or suborbiculate, 2–3.5 mm apex acute to rounded or emarginate, midrib included or exserted as mucro.
mostly dark brown to brown, globose to broadly ovoid, (2–)2.5–3(–4) mm, apex acute;
fertile scales broadly ovate to orbiculate, 1.7–2.3 mm, apex obtuse to rounded or emarginate, midrib mostly included, sometimes excurrent as apiculus.
perianth bristles mostly 6, rarely reaching fruit midbody, antrorsely barbellate.
perianth bristles 6 or less, antrorsely barbellate, of various lengths.
mostly 1 per spikelet, 2–2.5 mm, body dark brown, obovoid to subglobose, tumid or lenticular, 1.5–1.7 mm, transversely finely rugose to nearly level, intervals with very small, pitlike alveoli.
1–3 per spikelet, 1.5–1–8 mm (–2 mm in var. pinetorum);
body tumidly biconvex;
surfaces transversely wavyrugose, intervals of vertically rectangular alveolae or transverserugosity indistinct, surface isodiametrically alveolate or cancellate;
tubercle shortconic to patelliformapiculate.

1. Fruit body broadly obovoid to suborbicular, medially with mostly isodiametric tiny alveoli or pits, or minutely raised reticulate in an almost honeycomb pattern of alveolae, or simply evenly finely cancellate; ultimate spikelet complexes with clusters on stiffish branchlets, usually dense and exceeded at least by subulate tips of subtending leafy bract and bractlets. | var. harveyi |
1. Fruit body obovoid, lenticular, medially with oblong or roundish pitlike alveoli, intervals between contiguous transverse rows forming shallow, broad, pale, smooth ridges; ultimate spikelet clusters more sparse, on more slender, lax, erect to excurved branches and exceeding subtending bracts and bractlets. | var. culixa |
1. Spikelets ovoid; fruit body scarcely transversely wavy rugose, instead with transverse, undulate rows of subisodiametric to very broadly rectangular lattices or alveolae. | var. pinetorum |
1. Spikelets broadly ovoid to subglobose; fruit body distinctly transversely wavy-rugose, intervals composed of irregular rows of vertical, rectangular alveolae. | → 2 |
2. Perianth bristles not extending much beyond fruit midbody; tubercle low conic, distinctly narrower than rounded summit of fruit body. | var. globularis |
2. Perianth bristles extending at least to fruit tubercle, sometimes to tip; tubercle depressed conic or patelliform, apiculate, nearly as broad as more truncate summit of fruit body. | var. saxicola |
