Running Clubmoss, Lycopodium clavatum

This slideshow requires JavaScript.

Common clubmoss (Lycopodium clavatum) is, like most clubmosses, small, evergreen and perennial. Some species of clubmosses resemble miniature pine and cedar trees, or giant mosses. Common clubmoss’s horizontal stem creeps along the forest floor, with upright stems arising from it.  This “fern ally” (related to but not a true fern) reproduces with spores, not seeds, that are found in cone-like structures called strobili located at the end of stalks, looking somewhat like a candelabra.  At this time of year, if you tap one of the strobili, you may see a yellow cloud of spores released into the air.
