Amandinea devilliersiana is a species of crustose lichen in the family Caliciaceae, and found in South Australia. It was first described in 2013 by Australian lichenologists Jack Elix and Gintaras Kantvilas[1] [2] from a specimen collected on a granite boulder near the seashore in South Australia. The species epithet, devilliersiana, honours Brigitte de Villiers (frequent companion of Gintaras Kantvilas on lichen hunting expeditions).[2] Specimens used for the description came from both Tasmania and South Australia.[2]
