Acromastigum integrifolium: The Fascinating Moss of the Lepidoziaceae Family


Mosses are often overlooked, but they play crucial roles in ecosystems around the world. One particularly interesting moss is Acromastigum integrifolium (Austin) A.Evans, also known simply as Acromastigum. This small but mighty plant is part of the Lepidoziaceae family in the division Marchantiophyta, class

Jungermanniopsida. Let’s take a closer look at this fascinating moss species.


Acromastigum integrifolium was first described by American botanist Coe Finch Austin in 1869 under the name Lepidozia integrifolia. It was later reclassified into the genus Acromastigum by Alexander William Evans in 1934. The Lepidoziaceae family contains over 400 species of liverworts and a few mosses, mostly found in tropical and subtropical regions.

Morphology and Identification

Acromastigum integrifolium is a small, delicate moss that forms dense mats. Its leaves are ovate to oblong, 0.5-1 mm long, and arranged in two rows along the stem. The leaves are typically entire or slightly toothed at the apex. Acromastigum produces sporophytes (spore-producing structures) on short setae, with ovoid to cylindrical capsules

Identifying Acromastigum in the field requires close examination, as it can be confused with similar small mosses. Key characteristics to look for include:

Global Distribution and Habitat

Acromastigum integrifolium has a wide distribution, found in North America, Central America, South America, Europe, Africa, Asia, and Oceania. It grows in a variety of habitats, including:

  • Moist, shaded rocks and cliffs
  • Soil banks along streams and rivers
  • Rotting logs and tree bases in forests
  • Damp, sheltered crevices and caves

This adaptable moss can tolerate a range of environmental conditions but prefers

humid, low-light environments.

Ecological Roles and Adaptations

Like other mosses, Acromastigum plays important ecological roles:

  1. Erosion control: Its dense mats help stabilize soil and prevent erosion.
  2. Water retention: Acromastigum absorbs and retains water, regulating moisture in its environment.
  3. Habitat provision: It provides shelter and microhabitats for small invertebrates.
  4. Nutrient cycling

    : As it grows and decomposes, Acromastigum contributes to nutrient cycling in ecosystems.

Acromastigum has several adaptations that allow it to thrive:

Characteristic Description
Leaf shape Ovate to oblong
Leaf size 0.5-1 mm long
Leaf arrangement Two rows along stem
Leaf margin Entire or slightly toothed
Sporophytes On short setae, ovoid to cylindrical capsules


Acromastigum integrifolium may be small, but it is a remarkable moss with a wide distribution and important ecological roles. Its adaptations allow it to thrive in diverse habitats, from tropical forests to temperate caves. Next time you’re out in nature, take a closer look – you might just spot this fascinating plant!
