The genus Campylopus contains around 150 species of mosses found across the globe. They are classified in the Bryophyta division and Bryopsida class. Campylopus atrovirens is one of the more well-known species.
Morphology and Identification
C. atrovirens forms dense tufts or cushions. The leaves are lanceolate (lance-shaped) with hair-like tips. Under a microscope, the leaf cells are rectangular. The seta (stalk bearing the capsule) is red to reddish-brown. Capsules are ovoid and strumose (with a lump on one side of the base).
Global Distribution and Habitat
This moss has a wide distribution, found in Europe, Asia, Africa, and the Americas. It grows on acidic soils and rocks

Appalachian Mountains.
Ecological Roles and Adaptations
Like other mosses, C. atrovirens plays important roles:
- Erosion control

- Habitat for microorganisms: Many tiny creatures live among the leaves
The hair-points on the leaves help reflect sunlight, preventing the moss from drying out. The species is dioicous, meaning male and female reproductive structures are on separate plants.
