Xanthoparmelia delisei is similar to X. pulla from which it was not distinguished earlier. There are minute morphological differences (e.g., thallus colour) but it is undoubtedly distinguished by the presence of glomelliferic, glomellic and perlatolic acid and traces of other substances. Thin-layer chromatography is necessary, thallus spot reactions are not reliable.
The lichen mainly grows on sun-exposed acidic siliceous rocks, but may also be found on basic extrusive rocks and calcareous silicates. It is a thermophilic species, occurring at lower elevations. In central Europe, it appears to be quite common as suggested by data from Poland (Szczepańska & Kossowska 2014). In the Czech Republic, it has been confirmed from a couple of localities, e.g., in the Middle Vltava region and the Podyjí National Park, so far. A revision of the herbarium material of X. pulla agg. is necessary.
