Atla vitikainenii is a species of saxicolous (rock-dwelling) in the family Verrucariaceae. Found in northern Finland, it was formally described as a new species in 2016 by Juha Pykälä and Leena Myllys. The type specimen was collected by the first author from Oulanka National Park (Salla, Koillismaa), at an altitude of 185m (607feet); there, it was found growing on pebbles in a northeast-facing dolomite rock outcrop. The species epithet honours Finnish lichenologist Orvo Vitikainen, who, according to the authors, "has contributed in many ways to our knowledge of the taxonomy, ecology and biogeography of Finnish lichens".
