Adelanthus integerrimus Grolle: A Fascinating Moss of the Adelanthaceae Family
Introduction
Today we’re diving into the captivating world of Adelanthus integerrimus Grolle, a unique moss species of the Adelanthaceae family. This tiny but mighty plant plays important ecological roles and boasts some remarkable adaptations. Let’s explore what makes Adelanthus integerrimus so special!
Background on Adelanthus Mosses
The Adelanthaceae is a small family of liverwort mosses in the order Jungermanniales. Adelanthus is the type genus, which includes our star species –

Adelanthus integerrimus. These mosses are characterized by their creeping growth habit and lack of underleaves.
Morphology and Identification
Adelanthus integerrimus Grolle is a tiny moss, typically measuring just 2-10 mm long. It has a creeping, irregularly branched stem with obliquely inserted leaves. The leaves are ovate to oblong in shape with an entire or slightly toothed margin.
One key identification feature is the perianth, a tubular structure surrounding the female reproductive organs. In A. integerrimus, the perianth has a wide, truncate mouth that is entire or weakly lobed. Microscopic examination of leaf cells is often necessary for definitive ID.
Global Distribution and Habitat
A. integerrimus has a scattered global distribution, found in:

- North America (Pacific Northwest, Appalachians)
- South America (high Andes)
- East Asia (Japan, Taiwan)
This moss inhabits cool, humid environments in montane to subalpine elevations. Look for it on shaded rocks, cliffs, tree trunks and rotten logs in conifer or mixed forests. It seems to prefer

acidic substrates

.
Ecological Roles and Adaptations
Like other mosses, Adelanthus plays a vital role in its ecosystems:
- Regulating moisture by absorbing and slowly releasing water
- Providing shelter and food for invertebrates
- Contributing to nutrient cycling and soil formation
- Acting as a pioneer species on bare substrates
To thrive in its niche, A. integerrimus has developed key adaptations:
- Poikilohydry – can survive desiccation by suspending metabolic activity
- Efficient water and nutrient uptake

through its entire surface
- Asexual reproduction via fragmentation when conditions are unfavorable for sexual reproduction
Conclusion
Adelanthus integerrimus Grolle may be small, but this mighty moss is well-adapted to its cool forest habitats around the world. Next time you’re in a montane woodland, take a closer look – you might just spot this fascinating species! What other tiny treasures are waiting to be discovered in the world of mosses?
