Plants on rock, forming rounded cushionlike mats. Stems decumbent to short-creeping, dry stems readily fragmenting; irregularly forked, without budlike arrested branches, tips straight; main stem upperside and underside structurally slightly different, inconspicuously indeterminate, lateral branches radially symmetric, determinate, strongly ascending, 1-forked. Rhizophores borne on upperside of stems, throughout stem length, 0.2–0.35 mm diam. Leaves monomorphic, ± in alternate pseudowhorls of 4, tightly appressed, ascending, green, linear-oblong to linear-lanceolate, sometimes falcate on lateral rows (on main stem), 2–4.5 × 0.5–0.65 mm (usually smaller on young ascending branches); abaxial ridges present; base cuneate and decurrent (rounded and adnate on young branches), glabrous; margins short-ciliate, cilia transparent, scattered, spreading at base to ascending and dentiform toward apex, 0.07–0.15 mm; apex slightly attenuate and bristled or obtuse and abruptly bristled; bristle whitish or transparent, puberulent, 0.2–0.6 mm. Strobili solitary, 0.4–1.5 cm; sporophylls deltate-ovate or lanceolate, abaxial ridges moderately defined, base glabrous, margins short-ciliate to denticulate, apex acuminate with very short bristle.


Habitat: In rock crevices or on exposed rock
Elevation: 800–2800 m

Discussion

Selaginella leucobryoides has very tightly intertwined stems that readily fragment, a characteristic shared with S. utahensis and S. asprella. Selaginella leucobryoides is very closely related to, and difficult to separate from, S. utahensis (see discussion).
