Parmelia araucana Adler & Calvelo (in Calvelo & Adler 1999: 146)

Parnelia araucana was described by Calvelo & Adler (1999), and it has only been known from the type locality in Parque Nacional Lanín in the Neuquén province in central Argentina, until it was added from another locality in the neighbouring province of Río Negro ( Adler & Calvelo 2007). Stenroos (1991) described and illustrated a Parmelia with marginal isidia from Argentinian Tierra del Fuego, based on two collections housed in H. She concluded that it might represent an undescribed species, but that more material was needed. We believe these specimens represent P. araucana , although Adler & Calvelo (1993) already interpreted them within the variability of P. saxatilis . Parmelia araucana is reported here from four localities in Magallanes, in addition to two localities further to the north in Chile, both in deciduous and evergreen Nothofagus forests. The species has obviously been overlooked in southernmost South America. Parmelia araucana has not been included in any of the recent morphological and phylogenetic studies on Parmelia . From a biogeographical point of view it could be expected to belong in the new genus Notoparmelia , a mainly Southern Hemisphere genus deviating from Parmelia s. str. principally based on phylogeny and apothecium anatomy ( Ferencova et al. 2014). However, all our samples are sterile and a phylogenetic analysis is necessary to decide on its affiliation.
