A rare lichen, resembling small specimens of P. endophoenicea. They both have orange to red pigment in medulla; the pigmentation is, however, usually more intense and continuous in P. rubropulchra. The two species also differ in the character of soralia; in P. rubropulchra, they are more granular and usually not marginal. In the Czech Republic, P. rubropulchra occurs in the in the riparian forest area Soutok in southern Moravia. In grows on a bark of deciduous trees and on rocks. In Europe, it is a rare thermophilic species associated with humid lowland deciduous forests, even considered a preglacial relic (Masson 2008). Its Czech localities represent the northernmost border of its little-known European distribution range.
