ABSTRACT: An account of the lichen genus Graphina (Graphidaceae) in Australia is given. Of the 38 taxa recognized, nineteen are described as new and six are new reports for Australia. Graphina abdita, G. aquilonia, G. atramontana, G. atrocelata, G. atronitens, G. borealis, G. boweniana, G. celata, G. daintriensis, G. elaiocarpa, G. incisa, G. lumbschii, G. lumbschii var. deficiens, G. montoensis, G. nothofagi, G. psoromica, G. radicicola, G. rufopruinosa, and G. salazinica are described as new species and Graphina acharii, G. contorta, G. gracilescens, G. hiascens, G. mendax and G. pallido-ochracea are reported as new to Australia. In addition G. fissofurcata is reported to be saxicolous as well as corticolous. A lectotype is selected for G. pallido-ochracea. A key to the species found in Australia is given.
