Lecanographa lyncea é um líquen crustoso raro que cresce sobre a casca de árvores antigas e veteranas em florestas antigas. Produz apotécios lirelados alongados e é considerado um dos indicadores mais sensíveis de ecossistemas florestais não perturbados de longa continuidade na Europa. Criticamente Ameaçado, enfrenta grave ameaça por perda de habitat, declínio de árvores veteranas e poluição do ar.
