Haircap moss is a rare tall one among mosses: its stems grow to the height of a palm, leaves stiffly rising upward, dense patches joining into a sheet that from afar looks like tiny conifer seedlings just emerging—and it springs back underfoot.

The Tall One Among Mosses

Haircap moss is a rare tall one among mosses: its stems grow to the height of a palm, leaves stiffly rising upward, dense patches joining into a sheet that from afar looks like tiny conifer seedlings just emerging, and springs back underfoot.

Its stems are erect and hard, unlike most mosses’ soft sprawl. Look close and the leaf margins curl slightly inward, the leaves bearing vertical lamellae—ribs the moss has added to itself.

— Botany Notes, self-inscription —

A body of stiff leaves, a miniature pine;

a headful of golden threads that will not droop.

The Origin of the Golden Hair

Its name comes from the spore capsules: at maturity they gleam golden, each capped with a fuzzy little hood, hanging like a head of golden hair. Then the whole clump stands full of small columns, golden at a distance.

Among mosses, this kind of flowering-like display is rare. Most moss capsules are too small to see clearly; only in its mature season can you recognize it at a glance from under the trees.

Tinder for the Flint

Old mountain folk used it as tinder: dried haircap moss is fluffy and quick to catch, stuffed into a flint and lit at one spark. A patch of forest moss saved people a great deal of fire-making trouble.

It loves shady, damp, acidic ground, common under conifer forest and on shaded slopes. In those places of little light and thin soil, it covers the ground leaf by leaf, slowly building a little humus.

• How to know it: Moss; stems erect and hard; leaves lanceolate with incurved margins and lamellae; capsules four-angled columns, hood densely hairy.
• Season: Capsules mature in summer and autumn—the golden season most striking; otherwise deep green tufts.
• Caution: Likes shady, damp, acidic ground; avoid dryness and strong light; collect sparingly for display, leave the colony to recover.

Groundcover and Observation

Today it serves as woodland groundcover and a supporting piece in terrarium scenes; botanically it is fine material for observing moss form—large, clear capsules and hoods make alternation of generations easy to explain.

Collecting and keeping it both require care for the environment: it depends on the forest-floor moisture and acidic substrate, and retreats when the surroundings change. The forest stands, it stands; cut the forest and it is gone.
