Bonfire moss is a tiny moss that moves onto old campfire sites, burned ground, and freshly disturbed soil, often among the first plants to return. Its stems are only about 1/8–3/8 in (3–10 mm) tall, but its long wiry stalks topped with lopsided, pear-shaped make it easy to spot. It grows across North America and much of the world, and is also called common cord-moss.

Appearance

Appearance
A soft, light green moss with a small rosette of oval leaves near the ground. In sunny spots, the leaves may turn orange-red before withering in the summer heat.
Growth form
Grows upright in dense little tufts.

Look-alikes

Urn mossPhyscomitrium pyriforme

Urn moss has short stalks, about 3/16–5/8 in (0.5–1.5 cm), with upright, urn-shaped capsules. Bonfire moss has much taller stalks with slanted, lopsided capsules.

Why they get mixed upThe two often grow side by side on disturbed soil, and plants without capsules are hard to tell apart.

Funaria flavicans

Its capsule mouth is less slanted, but the surest difference is in the tiny teeth around the capsule mouth, which needs magnification; photos usually aren't enough.

Why they get mixed upIt is a close relative in the same genus with a similar long stalk and tilted capsule.

Where it lives

Typical habitats
  • Burned ground
  • Old campfire sites
  • Disturbed soil
  • Flowerpots and greenhouses
  • Sidewalks and walls
Range
Found nearly worldwide, especially in temperate regions, and widespread across North America; in Illinois, for example, it probably grows in every county.
Preferred conditions
Prefers moist, bare, often nutrient-rich soil in sun to light shade, such as abandoned farm fields, roadsides, railroad edges, and patio cracks.

Life cycle

Reproduction
Spore stalks run about 3/4–2 in (2–5 cm) long, green at first and red when mature. They twist and untwist as the humidity changes, which helps shake the spores loose. It is one of the earliest mosses to produce capsules in spring, and spores are usually released from late spring to midsummer.

Culture and stories

Culture and stories
  • The species name hygrometrica refers to the way its stalks twist and untwist with changes in humidity, like a tiny humidity gauge.
  • It can be a stubborn weed in greenhouses and nursery pots.
