It is a spore-bearing vascular plant, growing mainly prostrate along the ground with stems up to 1 m long; the stems are much branched, and densely clothed with small, spirally arranged leaves. The leaves are 3–5 mm long and 0.7–1 mm broad, tapered to a fine hair-like white point. The branches bearing spore cones turn erect, reaching 5–15 cm above ground, and have fewer leaves than the horizontal branches. The spore cones are yellow-green, 2–3 cm long, and 5 mm broad. The horizontal stems produce roots at frequent intervals along their length, allowing the stem to grow indefinitely along the ground. The stems superficially resemble small seedlings of coniferous trees, though it is not related to these.

It has a subcosmopolitan distribution, with distinct subspecies and varieties in different parts of its range:
Lycopodium clavatum subsp. clavatum

Although globally widespread, like many clubmosses, it is confined to undisturbed sites, disappearing from farmed areas and sites with regular burning. As a result, it is endangered in many areas. In the UK it is one of 101 species named as a high priority for conservation by the wild plant charity Plantlife
