Peltigera species macroscopically resembling P. canina, but with more or less simple to slightly branched rhizines, which are distinctly tomentose. Similar, but brush-like rhizines has P. membranacea. This taxon has not yet been formally described, although it has appeared in the literature for more than 20 years (Miadlikowska & Lutzoni 2000). At least within Europe, it is likely to be a widely distributed species. It prefers mossy rocks in forest environments (Timdal & Gjerlaug 2023). In the Czech Republic, the species is so far known from three localities in the Šumava Mts, Týřov and Velké Pleš in the Křivoklát region. It is likely that a substantial part of the earlier Czech records of P. membranacea will apply to it.
