Overview

Cut Notchwort (Tritomaria exsecta) is a small leafy liverwort characterized by its distinctive deeply notched leaves that give the species its common name. This bryophyte forms small, dark green to brownish patches and plays an important ecological role in nutrient cycling and moisture retention in specialized microhabitats.

Cut Notchwort (Tritomaria exsecta) is declining primarily due to habitat loss and degradation of its specialized bryophyte communities. Climate change and atmospheric pollution are altering the delicate moisture and chemical conditions required for this liverwort's survival, while human activities continue to fragment and destroy suitable habitats.

Threat summary

Habitat

Cut Notchwort grows exclusively on acidic rock surfaces, particularly on exposed siliceous outcrops, cliff faces, and boulder fields in montane and subalpine regions. It requires consistently moist conditions with high humidity and clean air, typically found in areas with frequent fog or mist.
