Acarospora rhabarbarina Hue, published as a replacement name for the later homonym Lecanora bella Nyl., is an illegitimate superfluous name because Nylander had previously published his own replacement name, L. xanthophana (≡ A. xanthophana (Nyl.) Jatta). Furthermore, Hue, Magnusson and other later authors misapplied the name A. xanthophana to a common South American taxon, which is described here as A. congregata , the epithet referring to the usual arrangement of the apothecia in groups in large areoles. Lecanora ochrophana Nyl., a synonym of A. xanthophana , is lectotypified. The question of conservation of names, including an explanation as to why it is not proposed in this case, is discussed.
