distinct capsule that is cylindrical in shape and can reach up to 3 mm in length. The capsule is borne on a short seta and is covered by a hairy calyptra.

Global Distribution and Habitat

Braunia macropelma has a wide global distribution, with populations found in North America, Europe, Asia, and Africa. This moss species is known to inhabit rocky substrates, particularly on exposed boulders and cliffs. It can thrive in both dry and humid environments, showcasing its adaptability to various ecological conditions.

Ecological Roles and Adaptations

Braunia macropelma plays a significant role in its ecosystem by contributing to soil formation and nutrient cycling. As a pioneer species, it helps to colonize bare rocks and create suitable conditions for other plants to establish. Braunia macropelma exhibits several adaptations that enable it to survive in harsh environments. Its thick-walled cells and water-retaining capabilities allow it to withstand periods of drought. Additionally, the hairy calyptra covering the capsule helps to protect the developing spores from desiccation.
