This, often blue-green Peltigera when wet, is recognizable also by the up-turned, inrolled or undulate, tomentose lobes, the absence of veins and the contrast between the pale edges and the black centre of thallus underside. Peltigera malacea is one of the typical acidophilous oligotrophic species occurring in grasslands and on bare soil from steppe communities to hight mountains. Its broad range covers mainly the temperate and boreal zones of the northern hemisphere and shows continental tendencies. In the past, the species occurred in the Czech Republic scattered in dry grasslands, sandplains, heathlands, forest edges and open dry forests. Nowadays, it is rare in the country. More of its recent localities are known only from the Třebíč region. Individual records come e.g. from the Strakonice and Třeboň regions, the Šumava Mts, the Slavkovský les Highlands and the Hrubý Jeseník Mts. Its decline was probably caused by the eutrophication, the subsequent overgrowth by strong competitors and also by the destruction of suitable habitats as a result of agricultural intensification.taxonomic classification:
