Peltigera Horizontalis
''Peltigera horizontalis'' is a species of lichen in the family Peltigeraceae. It was first described by British botanist William Hudson in 1762 as ''Lichen horizontalis''. German botanist Johann Christian Gottlob Baumgarten transferred it to the genus ''Peltigera ''Peltigera'' is a genus of approximately 100 species of foliose lichens in the family Peltigeraceae.

Peltigera
''Peltigera'' is a genus of approximately 100 species of foliose lichens in the family Peltigeraceae. Commonly known as the dog or pelt lichens, species of ''Peltigera'' are often terricolous (growing on soil), but can also occur on moss, trees, rocks, and many other in many parts of the world. Most species of ''Peltigera'' have the cyanobacterium ''Nostoc'' as the dominant photobiont but some have the algae '' Coccomyxa.'' The presence of both a green alga and a cyanobacterium makes some tripartite; in this case they show cephalodium growths containing the third partner, ''Nostoc''. Because of their ability to fix nitrogen from the atmosphere, such lichens are influential in soil composition and generation. Description Species of ''Peltigera'' are foliose, with broad lobed thalli. Although the size of the thalli is variable and species-dependent, in some species the thalli can grow quite large, up to 30 cm in diameter.Vitikainen O. (1994). (1998). Taxonomic notes on n ...

Lichens Of North America
Irwin Murray Brodo (born November 7, 1935 in New York City) is an emeritus scientist at the Canadian Museum of Nature, in Ottawa, Ontario, Canada. He is an authority on the identification and biology of lichens. Early life and education Brodo grew up in the Bronx and attended City College in Manhattan as an undergraduate. He went on to do his graduate studies at Columbia University, and received a master's degree from Cornell University. He earned a Ph.D. in lichenology under the supervision of Henry Imshaug at Michigan State University. Career and research In 1965, Brodo was hired by the National Museum of Canada (now the Canadian Museum of Nature), where he continues to work as a research scientist emeritus. Over his career, he has built the lichen collection (CANL) into one of the best in North America. His research includes in-depth studies on challenging genera such as ''Bryoria'', ''Lecanora'', and ''Ochrolechia''. His 1968 work on the lichens of Long Island and the ef ...

Lichens Of Canada
A lichen ( , ) is a hybrid colony of algae or cyanobacteria living symbiotically among filaments of multiple fungus species, along with yeasts and bacteria embedded in the cortex or "skin", in a mutualistic relationship.Introduction to Lichens – An Alliance between Kingdoms . University of California Museum of Paleontology. . Lichens are the lifeform that first brought the term symbiosis (as ''Symbiotismus'') into biological context. Lichens have since been recognized as important actors in and producers which many higher trophic feeders feed on, such as reindeer, gastropods, nematodes, mites, and springtails. Lich ...
