An accurate circumscription of the poorly known Punctelia negata (Nyl.) Krog
Keywords:
Brazil, Colombia, Punctelia borrerina.Abstract
The holotype of Punctelia negata and its isotypes were studied and compared to similar species. The type study confi rmed that P. negata has a pale lower surface and lobules on the upper surface rather than a black lower surface and no vegetative propagules, as reported previously. Brazilian collections identifi ed as P. negata present a black lower surface; therefore should be referred to P. borrerina (Nyl.) Krog. At present, P. negata is only known from the type locality in Colombia.
