Abstract

Three species of the Buellia epigaea-group, Buellia dijiana Trinkaus, Buellia georgei Trinkaus, Mayrhofer & Elix, and Buellia lobata Trinkaus & Elix, are described as new from Australia. The taxonomy, morphology, anatomy, chemistry, biogeography, and ecology of the three taxa are discussed. Characters which distinguish these species from the corresponding taxa in the northern hemisphere include secondary compounds (presence of xanthones) and filiform conidia. An extended key is provided for the whole Buellia epigaea group as well as other terricolous species of the genus.
