Abstract

The new lichenized ascomycete Tapellaria palaeotropica is described from Mahé Island in the Seychelles. The species is characterized by a crustose, pale green, smooth thallus dispersed in patches and by having black, rounded apothecia with flat discs, hyaline, transversely, 3–5-septate ascospores and a purplish brown excipulum. Morphology, distribution and related species are discussed. A world key to all currently known species in the genus is presented.
