kalkhaarschubje
Agonimia globulifera
Agonimia globulifera, commonly known as kalkhaarschubje, is a small crustose lichen species characterized by its pale, chalky appearance and distinctive globular reproductive structures. This inconspicuous lichen forms thin, whitish-gray crusts on calcareous substrates and plays an important ecological role in primary succession and nutrient cycling in limestone environments.

Species Profile
Agonimia globulifera, commonly known as kalkhaarschubje, is a small crustose lichen species characterized by its pale, chalky appearance and distinctive globular reproductive structures. This inconspicuous lichen forms thin, whitish-gray crusts on calcareous substrates and plays an important ecological role in primary succession and nutrient cycling in limestone environments.
Agonimia globulifera, a rare crustose lichen, faces severe threats from habitat loss and degradation of its specialized substrate requirements. Air pollution and climate change further compromise the specific environmental conditions this species needs to survive, while its extremely limited distribution makes it highly vulnerable to local disturbances.
Key Facts
Habitat & Distribution
Kalkhaarschubje grows exclusively on exposed limestone rocks, mortar of old walls, and concrete structures in areas with low air pollution. It typically colonizes vertical or slightly overhanging calcareous surfaces that receive moderate light but remain protected from direct rainfall.
