Dark Ditrichum
Ditrichum lineare
Dark Ditrichum is a small, tufted moss species characterized by its dark green to blackish-green coloration and narrow, linear leaves that give it its scientific name. This bryophyte forms dense, low cushions or mats and plays an important ecological role in soil stabilization and moisture retention in specialized microhabitats.

Species Profile
Dark Ditrichum is a small, tufted moss species characterized by its dark green to blackish-green coloration and narrow, linear leaves that give it its scientific name. This bryophyte forms dense, low cushions or mats and plays an important ecological role in soil stabilization and moisture retention in specialized microhabitats.
Dark Ditrichum (Ditrichum lineare) is critically endangered primarily due to habitat loss and degradation of its specialized wetland environments. This moss species requires very specific moisture and substrate conditions that are increasingly threatened by human activities and climate change.
Key Facts
Habitat & Distribution
Dark Ditrichum typically grows on calcareous soils, limestone outcrops, and disturbed ground in open areas with specific pH and moisture requirements. It is often found on thin soils over rock substrates, particularly in areas with seasonal moisture fluctuations.
