A large Peltigera species, characterized by tomentose lobes with down turned margins and by richly branched to confluent rhizines. The species grows on soil, humus, bryophytes, mossy tree bases, calcareous and siliceous rocks and on decaying trunks in both forest and open habitats. Despite its wide ecological amplitude, the lichen is rare in the Czech Republic and has apparently declined in the last century. There are numerous reports on the species occurrence in the Czech Republic in the old literature, but they must be taken with caution since this name served as a bin for a large group of Peltigera species with wide tomentose lobes in the past. Peltigera canina seems to be sensitive to eutrophication and changes in the landscape management. A relatively higher concentration of its localities is currently known only from the western part of the country. In Europe, the lichen is widespread and locally common.taxonomic classification:
