Background
Aulacopilum brittoniae Pursell is a species of moss first described by Richard Henry Pursell in 1994. It belongs to the Erpodiaceae family in the order Bryopsida of the division

Bryophyta. The Erpodiaceae family contains around 35 species found in tropical and subtropical regions worldwide.
Morphology and Identification
A. brittoniae forms small, dense cushions or mats. The stems are creeping and irregularly branched, reaching 5-10 mm long. Leaves are ovate-lanceolate, 0.5-1 mm long, with a short apiculus at the tip. The leaf margins are entire and the costa (midrib) is absent.
Identifying A. brittoniae requires microscopic examination. Key features include:
- Leaf cells that are smooth and hexagonal
- Presence of multicellular gemmae on the stems
- Capsules that are erect and cylindrical on short setae
Global Distribution and Habitat

- Panama
- Colombia
- Ecuador
This moss grows as an epiphyte on tree bark and branches in moist lowland to montane tropical forests. It prefers partial shade and high humidity.
Ecological Roles and Adaptations
Like other mosses, A. brittoniae plays important roles in its forest habitats:

- Provides shelter and food for micro-organisms and invertebrates
- Aids in nutrient cycling by trapping organic debris
- Can be a bioindicator of air quality and habitat health

A. brittoniae has adaptations for its epiphytic lifestyle:
- Stems and rhizoids anchor it to bark
- Dense growth form resists desiccation
- Leaves and stems absorb water and nutrients directly
Conclusion
Aulacopilum brittoniae Pursell may be tiny, but it is a prime example of how mosses are essential components of the ecosystems they inhabit. From its unique morphology to its ecological roles, this species reminds us to appreciate the small wonders of nature. Next time you’re in a tropical forest, take a closer look – you might just spot an Aulacopilum moss making its quiet but vital contribution. What other overlooked species are out there waiting to captivate us?
