Exploring the Fascinating World of Leucophanes horridulum Broth. Moss
Introduction
Mosses are often overlooked, but they play a vital role in many ecosystems around the world. One particularly interesting species is Leucophanes horridulum Broth.

, a moss in the Calymperaceae family. In this blog post, we’ll dive into the details of this fascinating plant.
Background
Leucophanes horridulum Broth. is a species of moss first described by Viktor Ferdinand Brotherus in 1895. It belongs to the genus Leucophanes and the family Calymperaceae. Mosses are non-vascular plants in the division

Bryophyta, class Bryopsida.
Morphology and Identification
L. horridulum forms dense, cushion-like tufts. The leaves are lanceolate (lance-shaped) and have a horrid (rough or bristly) appearance, hence the species epithet “horridulum“. The leaves have a costa (midrib) that extends to the apex. Sporophytes (spore-producing structures) are

rare.
Global Distribution and Habitat
This moss has a pantropical distribution, meaning it is found in tropical regions around the world, including parts of Africa, Asia, Australia, and the Americas. It typically grows on tree trunks and branches in humid forests at low to moderate elevations.
Ecological Roles and Adaptations
Like other mosses, L. horridulum plays important roles in its ecosystem:
- Water retention

- Habitat for micro-organisms: Many tiny creatures make their homes in moss tufts.
- Nutrient cycling: As mosses grow and decompose, they contribute to nutrient cycling.
