Blunt-bud Thread-moss
Pohlia bulbifera
Blunt-bud Thread-moss (Pohlia bulbifera) is a small acrocarpous moss characterized by its distinctive blunt-tipped propagules (bulbils) that form at the tips of specialized branches. This delicate moss typically grows in small, scattered patches and plays an important role in soil stabilization and moisture retention in its specialized microhabitats.

Species Profile
Blunt-bud Thread-moss (Pohlia bulbifera) is a small acrocarpous moss characterized by its distinctive blunt-tipped propagules (bulbils) that form at the tips of specialized branches. This delicate moss typically grows in small, scattered patches and plays an important role in soil stabilization and moisture retention in its specialized microhabitats.
Blunt-bud Thread-moss (Pohlia bulbifera) is critically endangered due to its extremely limited distribution and vulnerability to habitat disturbance. The species faces severe threats from human activities that alter its specialized bryophyte habitat requirements. Climate change and environmental modifications pose additional risks to this rare moss species.
Key Facts
Habitat & Distribution
Pohlia bulbifera grows on moist, mineral-rich soil along stream banks, seepage areas, and the edges of springs or wetlands. It typically colonizes disturbed or recently exposed soil surfaces where competition from other bryophytes and vascular plants is minimal.
Threats
IUCN Red List: Critically Endangered
