Jungermanniales. The Scapaniaceae family contains around 85 species found worldwide. The genus name Scapania comes from the Greek words “skapanē” meaning “spade” and “parvitexta” meaning “small woven”, referring to the small, spade-shaped leaves.
Morphology and Identification
S. parvitexta forms small, green to reddish-brown mats on rocks, soil, or tree bark. The shoots are prostrate to ascending, up to 2 cm long. Leaves are succubously inserted, complicate-bilobed with the dorsal lobe smaller than the ventral, and margins entire to slightly toothed.

Underleaves are absent. Gemmae are often produced in clusters at the tips of shoots.
Key identification features:
- Small size (shoots up to 2 cm)
- Succubous, complicate-bilobed leaves
- Lack of underleaves
- Frequent gemmae production
Global Distribution and Habitat
S. parvitexta has a wide distribution, found in Europe, Asia, Africa, and the Americas. It grows in a variety of habitats including on rocks, soil banks, rotting logs, and tree bases in forests. The species prefers

- Small, compact growth conserves moisture
- Frequent asexual gemmae allow easy dispersal and colonization of new areas
- Lacks complex conducting tissues as it absorbs water and nutrients over its surface
Conclusion
Scapania parvitexta Steph. may be small, but this mighty moss has an important place in the world’s ecosystems. From retaining moisture to providing habitats, it serves many vital functions.
