Bartramiaceae family, this moss is commonly known simply as Breutelia. In this blog post, we’ll dive into the captivating world of Breutelia incana and discover what makes this tiny plant so special.
Background on Breutelia incana
Breutelia incana is a species of moss classified in the Bryophyta division and Bryopsida class. It was first described scientifically by Thomas Taylor in 1846 and later reclassified into the Breutelia genus by August Jaeger in 1875. The species epithet “incana” means hoary or quite grey, referring to the appearance of the leaves.
Morphology and Identification
Breutelia incana forms loose tufts or mats, with stems reaching 2-10 cm long. The leaves are lanceolate, often falcate-secund (curved to one side), and have a single costa (midrib) that ends before the apex. The leaf margins are serrated. Capsules are ovoid to cylindrical on long setae and have a characteristic sulcate (grooved) appearance when dry.
Global Distribution and Habitat
This moss has a wide distribution, found in many parts of the world including Europe, Asia, Africa, Australia, and the Americas. It grows on soil, rock, or sometimes tree bases in various habitats such as woodlands, grasslands, and montane environments. Breutelia incana is able to tolerate a range of conditions but prefers slightly acidic substrates.

Ecological Roles and Adaptations
Like other mosses, Breutelia incana plays important ecological roles. It helps retain moisture in its environment, prevents soil erosion, and provides shelter and food for micro-organisms and small invertebrates. This species has adaptations like water-repellent leaves and desiccation tolerance that allow it to survive periodic drying.
