Lopezaria is a genus of lichenized fungi in the family Ramalinaceae.
The genus name of Lopezaria is in honour of Manuel López-Figueiras (1915-2012), who was a (Spanish-) Venezuelan botanist (Mycology and Lichenology), from the University of Havana (in Cuba).
The genus was circumscribed by Klaus Kalb and Josef Hafellner in Lich. Neotropici fasc. XI, vol.2 in 1990.
