Global Distribution and Habitat

A. concinnus has a subcosmopolitan distribution, found in Europe, Asia, Africa, Australia, and the Americas. It grows on shaded soil banks, rotting logs, tree bases, and damp rocks in forests from lowland to montane elevations.

Ecological Roles and Adaptations

As with other mosses, A. concinnus plays important roles in its ecosystems:

  • Regulating moisture and preventing erosion
  • Providing shelter for micro-organisms
  • Cycling nutrients
  • Acting as a pioneer species in disturbed habitats

Its small size and mat-forming growth allow it to exploit limited resources in shaded microhabitats. The numerous oil bodies likely provide protection against desiccation and freezing.


Acrobolbus concinnus may be a small moss, but it certainly isn’t boring! From its global distribution to its important ecological roles, this species demonstrates how even the most unassuming organisms can have a big impact. The next time you’re out in the forest, keep an eye out for this charming little moss. Who knows what other natural wonders you might discover when you start paying closer attention to the small things in life?
