The lichen was first formally described as a new species in 2009 by lichenologists Jan Vondrák, Pavel Říha, Ulf Arup, and Ulrik Søchting, who initially classified it in the genus Caloplaca.

In younger apothecia, the thalline exciple tends to be concealed beneath the true margin, while in older specimens, it is well-developed and persists.

[3] Flavoplaca austrocitrina, initially described from specimens collected in Ukraine, has an ecology in the Buenos Aires region of Argentina that is quite similar to its European counterparts.

[5] Flavoplaca austrocitrina has been identified in various European countries, including Austria, Bulgaria, Germany, Greece, the Czech Republic, Romania, Russia, and Slovakia.

The discovery of this species in South America, coupled with its established presence in Europe, suggests a potential for a wider global distribution.

[5] Flavoplaca austrocitrina has been identified as one of several saxicolous lichens responsible for the biofouling of crypts of historical and architectural interest at La Plata Cemetery in Argentina.
