Among the six species observed, Caloplaca cinnabarina was the most common. Lichen species were identified by observation under optical microscope and chemical reactions. The chemical composition of the paint was analyzed by IRS and the metal composition of the plates by SEM and EDS. SEM analysis also revealed paint cracking around the lichen and paint particles trapped in the thallus.application/pdfenginfo:eu-repo/semantics/openAccessCaloplaca cinnabarinaSEMEDSinfo:eu-repo/semantics/articleAtribución (Attribution): En cualquier explotación de la obra autorizada por la licencia será necesario reconocer la autoría (obligatoria en todos los casos).
