Bryophyta.
Morphology and Identification of B. chrysea
B. chrysea forms yellowish-green tufts or cushions. The stems are 1-10 cm long, with densely arranged leaves that are 2-4 mm long. The leaves are lanceolate with serrated margins and a distinct costa (midrib) that extends to the leaf tip. Capsules are ovoid and slightly curved, borne on 1-3 cm long setae.
Global Distribution and Habitat
This species has a wide distribution, found in Europe, Asia, Africa, Australia, and the Americas. It grows on soil, rocks, and rotten wood in moist habitats like stream banks, wetlands, and damp forests from lowlands to mountains.
Ecological Roles and Adaptations
Like other mosses, B. chrysea plays important roles in its ecosystems:
- Helps retain moisture and prevent erosion
- Provides habitat for micro-organisms and small invertebrates
- Pioneers disturbed sites and aids in succession
The moss has adaptations like water-absorbing leaves, rhizoids for anchoring, and desiccation tolerance to survive in its moist but variable habitats.
