Rinodina calcarea
Rinodina calcarea is a crustose lichen species that forms thin, grayish to whitish crusts on calcareous substrates. This inconspicuous lichen plays an important ecological role in nutrient cycling and soil formation processes, while also serving as a bioindicator of air quality in its specialized habitats.

Species Profile
Rinodina calcarea is a crustose lichen species that forms thin, grayish to whitish crusts on calcareous substrates. This inconspicuous lichen plays an important ecological role in nutrient cycling and soil formation processes, while also serving as a bioindicator of air quality in its specialized habitats.
Rinodina calcarea, a crustose lichen species, faces severe decline primarily due to habitat loss and degradation of its specialized calcareous substrates. Air pollution, particularly nitrogen deposition and acid rain, significantly impacts this pollution-sensitive species by altering the chemistry of its rocky habitats and reducing air quality.
Key Facts
Habitat & Distribution
Rinodina calcarea grows exclusively on natural limestone outcrops, calcareous rocks, and occasionally on old mortar of historic stone buildings. It typically colonizes exposed to semi-shaded vertical or sloping surfaces where calcium carbonate is readily available.
