Xanthoparmelia imitatrix was reported from one locality in Magallanes and two in Argentina (Santa Cruz and Tierra del Fuego) by Esslinger (1977). We have found it to be very common in the National Park Torres del Paine and from scattered localities elsewhere within the steppes of Magallanes, and 19 collections are cited here. All samples contain physodic acid.
