The lichen genera Phaeographis and Phaeographina (Graphidaceae) in Australia. 3. Phaeographis - new reports and new species

Abstract

An account is given of the species in the lichen genus Phaeographina (Graphidaceae) in Australia, other than those taxa based on Australian type specimens. An additional 14 species are recognised and of these seven are described as new species: Phaeographina atromaculataA.W. Archer, P. fuscescensA.W. Archer, P. hadrosporaA.W. Archer, P. impudicaA.W. Archer, P. litoralisA.W. Archer, P. montiscalviA.W. Archer and P. wilsoniiA.W. Archer. Phaeographina arechavaletae Müll. Arg., P. caesioradians (Leight.) Redinger, P. exilior (Vain.) Zahlbr. and P. montagnei (v.d. Bosch) Müll. Arg. are reported as new to Australia. Phaeographina banksiae Müll. Arg. is reported as a synonym of P. arechavaletae Müll. Arg. and Phaeographina contexta (Pers.) Müll. Arg. is shown to belong to the genus Graphina. The epithets ‘chrysentera’ and ‘quassiaecola’ have been corrected to ‘chrysenteron’ and ‘quassiicola’ respectively. A key to all the Phaeographina species in Australia is given.
