They are [[flower]]less, vascular, terrestrial or [[epiphyte|epiphytic]] [[plant]]s, with widely branched, erect, prostrate, or creeping stems, with small, simple, needle-like or scale-like [[leaf|leaves]] that cover the stem and branches thickly.<ref name="EB1911" /> The stems usually creep along the ground, forking at intervals.<ref name="Peninsula">{{Cite book |last=Levyns |first=M.R. |title=A Guide to the Flora of the Cape Peninsula |publisher=Juta & Company, Limited |year=1966 |edition=2nd Revised |oclc=621340}}</ref> The leaves contain a single, unbranched vascular strand, and are [[microphyll]]s by definition.<ref name="EB1911" /> They are usually arranged in spirals.<ref name="Peninsula" /> The kidney-shaped (reniform) [[spore]]-cases ([[sporangium|sporangia]]) contain spores of one kind only, ([[spore|isosporous, homosporous]]), and are borne on the upper surface of the leaf blade of specialized leaves (sporophylls) arranged in a cone-like [[strobilus]] at the end of upright stems.<ref name=EB1911/> Each sporangium contains numerous small spores.<ref name="Peninsula" /> The club-shaped appearance of these fertile stems gives the clubmosses their common name.

Lycopods reproduce asexually by spores. The plants have an underground sexual phase that produces [[gamete]]s, and this alternates in the lifecycle with the spore-producing plant. The prothallium developed from the spore is a subterranean mass of tissue of considerable size, and bears both the male and female organs ([[antheridium|antheridia]] and [[archegonia]]).<ref name=EB1911/>  They are more commonly distributed vegetatively, though, through above- or below-ground [[rhizomes]].
