Peltigera canina, commonly known as the dog lichen, is a widely distributed species of foliose lichen in the family Peltigeraceae. It was originally described by Carl Linnaeus in his 1753 work Species Plantarum . German botanist Carl Ludwig Willdenow transferred it to the genus Peltigera in 1787. [2] This species is currently undergoing research as it is likely multiple species under one united name.
Peltigera canina has a brown to brownish-grey thallus when dry. The upper surface of the lobes, which generally measure 10–25 mm (0.4–1.0 in) across, have a fuzzy tomentum, especially near the margins. The lichen typically grows on soil, in woodlands, fields, and sandy areas [3] The cyanobiont Nostoc associates with Peltigera canina, and resembles the species N. sphaericum and N. punctiforme . [4]
