Imshaugia aleurites (Ach.) S.F.L. Mey. (1985: 338)

In addition to Parmeliopsis hyperopta, Calvelo & Liberatore (2002) also listed P. pallescens (Neck.) Zahlbr., from Argentina, referring to its inclusion from Argentinian Tierra del Fuego by Grassi (1950), whose source was Räsänen (1932), both treating it as Parmelia pallescens (Neck.) Räs. However, P. pallescens is a synonym of Imshaugia aleurites ( Santesson et al. 2004) , and not Parmeliopsis hyperopta , although listed as such by Räsänen (1932). His inclusion of the character ‘soredia semisphaeroidea’ indicates that the species in question is P. hyperopta , which has been confirmed by us by a study of the reported collection at S. Thus, Imshaugia aleurites remains unknown from South America.
