This is the last in a series of books illustrating Brazilian lichen specimens collected by the second author in the past decade. This volume includes some specimens and species that were not treated in previous books. As ever, it includes many isotypes of species that were recently described. The main purpose is to give many people virtual access to these unique specimens.
