The panaustral lichen Pannaria sphinctrina (Mont.) Tuck. and the related new species P. lobulifera from New Caledonia

Pannaria sphinctrina (Mont.) Tuck. is redefined as an exclusively panaustral lichen species, characterized by thin thallus lobes, ellipsoid, verrucose perispores and with vicanicin as its major secondary metabolite. Pannaria lobulifera sp. nov. is described here as the only species known from the P. sphinctrina complex in New Caledonia. Instead of apothecia it produces vegetative propagules in the form of erect lobules. Its lobes are also thinner, rhizines are practically lacking and chlorobiont cells are much smaller than those of P. sphinctrina.
