'''''Punctelia borrerina''''' is a species of foliose lichen in the family Parmeliaceae. It is found in Mexico and South America.

==Taxonomy== The lichen was first formally described as ''Parmelia borrerina'' by Finnish botanist William Nylander in 1896. The type specimens were collected in Rio Grande do Sul, Brazil. Nylander described the species as somewhat similar to ''Parmelia borreri'' (now the type species of ''Punctelia''), but with different chemistry: in ''P.&nbsp;borrerina'', the medulla has C− and KC− spot test reactions, while ''P.&nbsp;borreri'' is C+.<ref name="Nylander 1896"/> Hildur Krog transferred ''Parmelia borrerina'' to the new genus ''Punctelia'' in 1982.<ref name="Krog 1982"/> ''Punctelia borreri'' var. ''allophylla'' is considered to be a synonym of ''P.&nbsp;borrerina''.<ref name="Canêz & Marcelli 2010"/>

==Description== ''Punctelia borrerina'' produces ascospores that are less than 20&nbsp;μm long, and long-filiform (threadlike) conidia that are typically 10–15&nbsp;μm long.<ref name="Canêz & Marcelli 2010"/>

The lichen is a member of the ''Punctelia microsticta'' group, a set of similar species with a black thallus undersurface and lacking vegetative propagules; the other members of this group are ''P.&nbsp;jujensis'', ''P.&nbsp;microsticta'', ''P.&nbsp;riograndensis'', and ''P.&nbsp;subpraesignis''.<ref name="Canêz & Marcelli 2010"/>

==Distribution== In addition to Brazil, ''Punctelia borrerina'' has also been reported in Argentina and Uruguay.<ref name="Canêz & Marcelli 2010"/> In Mexico, it has been found in San Luis Potosí, Tamaulipas, and Veracruz.<ref name="Ryan et al. 2000"/>
