摘要
Three new corticolous lichen species are described from the Chapada do Araripe, an isolated table mountain in the state of Ceara, in NE Brazil. Eschatogonia granulosorediata has dissected ascending squamuks and granular soredia that originate marginally but extend to form laminal heaps. Gassicurtia caririensis has a granular, greenish grey thallus with thiophanic acid, a red medulla with chiodectonic acid and copious punctiform red soredia, apothecia black, not pruinose, ascospores 8/ascus, 8.5-11.5 x 3-4 gm. Gassicurtia rubromarginata has a granular, greenish grey thallus with thiophanic acid but without red medulla or soredia, apothecia black with partly red margin, whitish pruinose or not, ascospores 8.5-10.5 x 4-5 mu m.
