Introduction
Mosses are often overlooked, but they play a vital role in many ecosystems around the world. One particularly interesting species is Orthotrichum brotheri Dusén ex Lewinsky, a type of moss in the Orthotrichaceae family. In this blog post, we’ll dive into the details of this fascinating plant.
Background
Orthotrichum brotheri is a species of moss first described by Swedish botanist Per Karl Hjalmar Dusén in 1905. It belongs to the division Bryophyta

and class Bryopsida. The Orthotrichaceae family contains around 900 species found worldwide.
Morphology and Identification
O. brotheri forms small cushions or tufts on tree bark or rocks. The leaves are lance-shaped, 2-3 mm long, with a strong midrib. Capsules are cylindrical, 1.5-2 mm long, with 8 ridges when dry. The calyptra (hood) is bell-shaped and hairy.
Key identification features:
- Leaves: Lance-shaped with strong midrib
- Capsules: Cylindrical with 8 ridges
- Calyptra: Bell-shaped and hairy
Global Distribution and Habitat
O. brotheri has a wide distribution, found in:
- Europe (Scandinavia, Central Europe, British Isles)
- Asia (Russia, China, Japan)
- North America (Alaska, Canada, northern U.S.)
It typically grows on the bark of deciduous trees or occasionally on rocks in forests and wooded areas from lowlands to mountains.
Ecological Roles and Adaptations
Like other mosses, O. brotheri plays important roles in its ecosystem:
- Helps retain moisture and prevent erosion
- Provides shelter and food for small invertebrates
- Pioneers on bare substrates, paving the way for other plants
It has several adaptations for survival:
- Tolerates periods of desiccation
- Reproduces via spores dispersed by wind
- Absorbs water and nutrients over entire surface
Conclusion
Orthotrichum brotheri may be small, but it’s a remarkable and important species. Next time you’re in the woods, take a closer look at the tree trunks – you just might spot this intriguing moss! What other overlooked organisms in nature have caught your interest?
