'''''Punctelia digitata''''' is a species of foliose lichen in the family Parmeliaceae. Found in Brazil, it was described as a new species in 2009 by lichenologists Patrícia Jungbluth, Marcello Marcelli, and John Alan Elix. The holotype was collected from Itirapina municipality in São Paulo State. It was found growing on a tree trunk in a cerrado forest, at an altitude of {{convert|770|m|ft|abbr=on}}. The thallus is greyish in colour, measuring {{convert|4.5|–|10|cm|in|abbr=on|0}}, comprising irregularly branched lobes with a width of {{convert|2|–|4|mm|in|abbr=on|2}}. The specific epithet ''digitata'' (Latin for "finger-like") refers to the characteristic shape of the lacinules (vegetative propagules). The lichen contains trace amounts of atranorin, and lecanoric acid as the main secondary metabolite.<ref name="Marcelli et al. 2009"/>
