Description

A description of Lycopodiella alopecuroides is provided in The Flora of North America.

"Stems subterranean or on the surface, branching dichotomously and ascending or dividing into horizontal and erect branches. Roots adventitious along the creeping stem. Leaves numerous, small, scale-or awn-like, to 13 mm long, appressed or spreading, sometimes partly fused with the branch, simple, entire or toothed, with a midrib only. Sporophylls more or less like the sterile leaves, either in cauline bands or clustered in sessile or pedunculate, terminal strobili. Sporangia solitary at the leaf base, subglobose to reniform, opening by a transverse slit; spores uniform, tetrahedral. Gametophytes epigeous, green and thalloid, or fleshy, subterranean and mycorrhizal." - Radford et al 1964

"Sterile stems not dorsiventral, arching and rooting at the tip or procumbent and rooting throughout, 2-5 dm long, 3-4 mm in diam.; leaves deciduous except for the evergreen apex (“bud”). Leaves linear-subulate, upcurving, strongly ciliate-denticulate. Fertile stems erect, widely spaced, rarely forking or fascinated, 10-45 cm long, 2-3 mm in diam., 5-13 mm broad including the leaves which are as those of the procumbent branches but longer, ascending, more or less flat when dry, and densely overlapping. Strobili usually solitary, 2-10 cm long, 11-20 mm broad, conspicuously broader than the stem, Sporophylls subulate, spreading, strong ciliate-denticulate. Sporangia globose. Plants without gemmae." - Radford et al 1964

Ecology

Habitat

L. alopecuroides occurs in moist to wet semi-shaded soils (FSU Herbarium). Typical soil types range from sandy-peaty soils to loamy sand (FSU Herbarium). This species can be found in several native habitats, but also in disturbed areas. Native habitat types include wet pine savanna (Brewer et al 2011), hillside bogs, seasonally inundated meadows, damp grassy palmetto woods, and on the edges of ponds, creeks and titi thickets (FSU Herbarium). It also occurs in disturbed habitat like powerline corridors, roadsides, railways, pine plantations, and borrow pits (FSU Herbarium). Associated species include Ilex myrtifolia, Nyssa biflora, Pinus palutris, Aristida stricta, Cyrilla racemiflora, Juncus, Sarracenia, Rhynchospora, Xyris, Eriocaulon, Liquidambar styraciflua, Quercus laevis, Pinguicula, Kalmia hirsuta, Serenoa repens, Hypericum, Cliftonia, and Magnolia virginiana (FSU Herbarium).

Fire ecology

This species occurs in habitat that is maintained by frequent or annual fire (FSU Herbarium).
