Stag's-horn clubmoss

About

Stag's-horn clubmoss is an evergreen spore plant with long creeping stems that spread along the ground for a meter or more and occasionally root. The stems and ascending branches are densely covered with small soft leaves. Each leaf ends with a long white hair, making the shoots appear fluffy — this feature makes the species easily recognizable.

In July and August, thin yellowish legs 5–15 cm tall rise above the shoots, and on each sit two or three narrow spikes. They contain small yellow spores. The powder from the spores — lycopodium — does not get wet and flashes brightly when sprinkled over a flame. It was once used to dust pills, as baby powder, and for stage effects.

In the Carpathians, Stag's-horn clubmoss grows in dry coniferous and mixed forests, on forest edges, old pastures, in blueberry thickets, and wastelands on acidic soils — from the foothills to the subalpine zone.

Like all clubmosses, it develops very slowly: it takes more than ten years from spore germination to mature plant. Therefore, thickets pulled for wreaths or Easter decorations take decades to recover.

This species is not listed in the current Red Book of Ukraine, unlike Lycopodium annotinum and Lycopodium clavatum. However, picking any plants in reserves and national parks is prohibited, and in the EU, all clubmosses belong to species whose collection may be restricted.

When to see it

From naturalists’ observations in the Carpathians (iNaturalist, research grade): the darker the cell, the more often the species is seen that month.
