抄録

  The taxa belonging to the Lecanora subfusca group occurring in Australia, New Zealand and Papua New Guinea are revised. The morphology and anatomy of the members of the group is shown and the chemistry of the treated species is described. The substances found are ordered into chemosyndromes and the taxonomic significance of these is discussed. 46 taxa are accepted, four without formal description. A number of species is reduced into synonymy and most names treated are typified. Seven species are reported for the first time from the southern Hemisphere and eight for Australasia. The following new taxa are described: L. arnhemica, L. arthothelinella, L. austrotropica, L. casuarinophila, L. cenisioides, L. chionocarpoides, L. neoqueenslandica, L. novaeguineae, L. novaehollandiae, L. planaica, L. pseudargentata and L. streimannii.
