X. subhosseana (Elix) O. Blanco, A. Crespo, Elix, D. Hawksw. & Lumbsch (2004b: 971)

The species was reported with one locality from Santa Cruz and two from Magallanes by Esslinger (1977), and from Santa Cruz as new to Argentina by Calvelo & Liberatore (2002). Xanthoparmelia subhosseana appears to be scattered in the National Park Torres del Paine, but more common in steppes elsewhere in Magallanes, and was noted in the field to be the most common brown Xanthoparmelia species at Morro Chico. All the studied specimens were found to contain hypostictic, hyposalazinic and hypoconstictic acids.
