Vondrak, Jan & Jaroslav Soun. An appraisal of the syntype material of Caloplaca aurantiomurorum(Teloschistaceae, lichenized fungi). Mycotaxon 97: 67-71. 2006.

ABSTRACT: Sample no. 54 of Flagey: Lichenes Algerienses exsiccati represents the syntype of Placodium aurantiomurorum (basionym: Caloplaca aurantiomurorum). However, the samples of this exsiccatum distributed to FH, H, M, PC and UPS contain different lichen species. The lectotype of P. aurantiomurorum is selected here (sample in UPS) and this name is treated as a synonym to Caloplaca aurantia. In this exsiccatum, Candelariella senior has been identified (in H, FH, and PC), which is reported here as a new species to Algeria. The known distribution of Can. senior is described.
