Candelariella vainioana is a species of crustose lichen in the family Candelariaceae. It was described by Finnish lichenologist Rainar Hakulinen in 1954 from collections made by Edvard August Vainio in Hollola in 1874. The specific epithet vainioana honours Vainio. The lichen has been reported from Finland, Sweden, and Norway. The lichen's common name in Swedish is kopparägglav, and kuparikeltuaisjäkälä in Finnish, both of which mean "copper egg-yolk". As of 2019, it is considered to be an endangered species in Finland due to its small population.

Catillaria is a genus of crustose lichens in the family Catillariaceae. The genus was circumscribed by Italian lichenologist Abramo Bartolommeo Massalongo in 1852. It is the type genus of Catillariaceae, which was circumscribed by Austrian lichenologist Josef Hafellner in 1984.
Allographa leptospora is a species of script lichen in the family Graphidaceae. The lichen was first formally described in 1921 by Finnish lichenologist Edvard August Vainio as Graphis leptospora. The type specimen was collected in 1904 by German botanist Carl Curt Hosseus on Doi Suthep, where it was found growing on tree bark. Hosseus sent this and other lichens collected from Thailand to Vainio for identification. Robert Lücking and Klaus Kalb transferred it to the genus Allographa in 2018. In 2016, the lichen was reported from the Sintra Mountains, Portugal, which was its first documented occurrence in Europe.
