During ecological studies on corticolous lichens in Restinga vegetation in northeastern Brazil, many species of crustose Caliciaceae formerly placed in the collective genus Buellia s.l. were collected. A new species was discovered and is described here—Gassicurtia restingiana D.S.Andrade, M.Cáceres & Aptroot differs from G. catasema in the absence of lichexanthone. Two identification keys are provided, one for all species of Gassicurtia known from Brazil, and one for crustose, epiphytic, non-mazaediate species of Caliciaceae found in Restinga areas in northeastern Brazil.
