One of the three Czech „green“ Peltigera species that have green algae as the main photobiont. The lichen is ecologically vicarious to P. aphthosa, which is acidophilous and differs in the absence of veins on the thallus underside. Peltigera leucophlebia grows on soil, often in association with bryophytes, and on mossy rocks. It largely prefers neutral to basic substrates. Generally, the species is more common in mountain areas, although most of the historical data from the Czech Republic comes from lower and middle elevations. This is caused mainly by its affinity to calcareous substrates. Recently, the species has been recorded in the valley of Křemelná in the Šumava Mts and in the cirques Velká Kotlina in the Hrubý Jeseník Mts, Obří důl and Kotelní jámy in the Krkonoše Mts.
