and uncover its secrets.


Frullania tenera is a member of the Marchantiophyta division and Jungermanniopsida class of mosses. It was first described by Sextus Otto Lindberg and Franz Stephani

in the late 19th century. Since then, it has been studied for its distinctive morphology and wide global distribution.

Morphology and Identification

One of the most striking features of Frullania tenera is its small size. The shoots typically measure between 0.5 to 2 cm

in length and are densely branched. The leaves are arranged in two rows and are deeply bilobed, with the upper lobe being larger than the lower one. The underleaves are also bilobed and are usually smaller than the leaves.
Identifying Frullania tenera requires careful observation of its microscopic features. The leaf cells are small and have thick walls, while the oil bodies are few and large. The perianths, which enclose the female reproductive structures, are obovoid and have a distinct beak.

Global Distribution and Habitat

Frullania tenera

has a wide global distribution, found on every continent except Antarctica. It thrives in a variety of habitats, including:

  • Temperate forests
  • Subtropical regions
  • Montane areas
  • Coastal environments

This adaptable moss can grow on various substrates, such as tree bark, rocks, and even man-made structures like walls and fences. Its ability to tolerate a wide range of environmental conditions has contributed to its success and widespread distribution.

Ecological Roles and Adaptations

Despite its small size, Frullania tenera plays significant ecological roles. It contributes to:

  • Nutrient cycling
  • Water retention
  • Providing shelter for microorganisms

One of the most remarkable adaptations of Frullania tenera is its ability to survive periods of drought. When water is scarce, the moss can enter a dormant state, curling its leaves to minimize water loss. Once moisture returns, it quickly rehydrates and resumes growth.
