Xanthoparmelia plittii is mainly a pantemperate-subtropical American species, very similar to X. conspersa. It differs mainly by the brown lobe underside. It contains the same secondary metabolites, but the stictic acid complex may sometimes be missing. It had been overlooked in Europe for a long time, but recently, it has been recorded in many countries. For example, it is known from Smrčiny Hills in Germany and it is scattered in the east half of Poland. Similar to other Xanthoparmelia species, it grows on sun-exposed acidic rock. There is a single record from the Czech Republic (Týřov in the Křivoklát region), but it is probably overlooked.
