Exploring the Fascinating World of Entodon obtusatus Broth. Moss

Introduction

Mosses are often overlooked, but they play crucial roles in ecosystems around the world. One particularly interesting species is Entodon obtusatus Broth., a moss in the Entodontaceae family. In this blog post, we’ll dive into the details of this fascinating plant.

Background

Entodon obtusatus Broth., also simply called Entodon, is a species of moss in the Bryophyta

division and Bryopsida class. Mosses are non-vascular plants that lack true roots, stems, and leaves. Instead, they have leaf-like structures called phyllids that absorb water and nutrients.

Morphology and Identification

E. obtusatus

forms dense mats with creeping stems. The phyllids are ovate-lanceolate in shape, 0.7-1.2 mm long, and have a short, double costa (midrib). The seta (stalk bearing the capsule) is 8-15 mm long and the capsules are cylindrical, 1.5-2 mm long.
Key identification features:

• Ovate-lanceolate phyllids
  

  

• Short, double costa
• Cylindrical capsules on 8-15 mm setae

Global Distribution and Habitat

E. obtusatus has a wide distribution, found in North America, Europe, Asia, Africa, and Australia. It grows on various substrates including soil, rocks, tree bases and logs in forests and wooded areas from lowlands to mountains.

Ecological Roles and Adaptations

Like other mosses, E. obtusatus plays important roles in its ecosystems:

• Helps retain moisture and prevent erosion
• Provides habitat for micro-organisms
  

  

• Pioneers disturbed sites and aids succession
• Indicator of air quality as it absorbs pollutants

E. obtusatus has adaptations that allow it to thrive:

• Tolerates periodic drying with ability to rapidly rehydrate
  

  

• Grows in dense mats that aid moisture retention
• Reproduces via spores and asexual fragmentation

Conclusion

Entodon obtusatus Broth. is a prime example of how even tiny mosses can be fascinating. From its global distribution to its ecological importance, this species illustrates the significant roles mosses play. Next time you see a moss mat, take a closer look – it may be E. obtusatus!
