hyaline hair-point, is a key identifier for the species. The capsules, which contain the spores, are immersed within the tufts, adding to the moss’s unique appearance.

Global Distribution and Habitat

This remarkable moss has a widespread distribution, found across various regions of the Northern Hemisphere, including Europe, Asia, and North America. It thrives in a diverse range of habitats, from temperate forests to mountainous areas, often growing on the bark of trees, rocks, and even man-made structures like walls and roofs.

Ecological Roles and Adaptations

Despite its diminutive size, Ulota rehmannii Jur. plays a vital role in its ecosystems. It contributes to the formation of microhabitats, providing shelter and moisture for other organisms, such as invertebrates and fungi. Additionally, this moss exhibits remarkable adaptations to survive in harsh environments, including the ability to withstand desiccation and rapidly rehydrate when moisture becomes available.
