Species Profile
Glypholecia scabra is a crustose lichen species that forms thin, grayish to brownish crusts on calcareous substrates. This inconspicuous lichen plays an important ecological role in nutrient cycling and provides microhabitat for small invertebrates in limestone ecosystems.
Glypholecia scabra faces severe decline primarily due to air pollution and habitat degradation affecting the specific environmental conditions required for this lichen species. The species is particularly vulnerable to changes in air quality and substrate availability in its specialized coastal and rocky habitats.
Key Facts
Habitat & Distribution
Glypholecia scabra grows exclusively on calcareous rocks, limestone cliffs, and old mortar of stone walls in areas with relatively clean air. It typically occurs in semi-shaded to exposed situations on vertical or near-vertical surfaces where calcium carbonate is readily available.
Threats
