Main Content
Morphology and Identification
Fossombronia angulosa is a thallose liverwort, meaning it grows in a flat, ribbon-like form. Its thalli are typically green to yellowish-green in color and can reach lengths of up to 2 centimeters. One of its distinguishing features is the presence of angular to crescent-shaped gemmae cups on the thallus surface, which aid in its vegetative reproduction.
Global Distribution and Habitat
This moss species has a widespread distribution, occurring on various continents, including Europe, Asia, Africa, and North America. It thrives in moist and shaded environments, often found growing on soil, rocks, or decaying wood in forests, grasslands, and even urban areas.
Ecological Roles and Adaptations
Despite its small stature, Fossombronia angulosa plays a vital role in its ecosystems. It contributes to soil formation and moisture retention, creating microhabitats for other organisms. Additionally, this moss exhibits remarkable adaptations, such as the ability to
