Lichen Symbiosis of fungi with algae or cyanobacteria

A lichen is a composite organism that arises from algae or cyanobacteria living among filaments of multiple fungi species in a mutualistic relationship. Lichens have properties different from those of their component organisms. Lichens come in many colors, sizes, and forms and are sometimes plant-like, but lichens are not plants. Lichens may have tiny, leafless branches (fruticose), flat leaf-like structures (foliose), flakes that lie on the surface like peeling paint (crustose), a powder-like appearance (leprose), or other growth forms.

<i>Cladonia</i> Genus of lichenised fungi in the family Cladoniaceae

Cladonia is a genus of moss-like lichens in the family Cladoniaceae. They are the primary food source for reindeer/caribou. Cladonia species are of economic importance to reindeer-herders, such as the Sami in Scandinavia or the Nenets in Russia. Antibiotic compounds are extracted from some species to create antibiotic cream. The light green species Cladonia stellaris is used in flower decorations.

Cladoniaceae Family of fungi

The Cladoniaceae are a family of lichenized fungi in the order Lecanorales. It is one of the largest families of lichen-forming fungi, with about 560 species distributed amongst 17 genera. The reindeer moss and cup lichens (Cladonia) belong to this family. The latter genus, which comprises about 500 species, forms a major part of the diet of large mammals in taiga and tundra ecosystems. Many Cladoniaceae lichens grow on soil, but other can use decaying wood, tree trunks, and, in a few instances, rocks as their substrate. They grow in places with high humidity, and cannot tolerate aridity.

Parmeliaceae Family of lichens

The Parmeliaceae is a large and diverse family of Lecanoromycetes. With over 2700 species in 71 genera, it is the largest family of lichen-forming fungi. The most speciose genera in the family are the well-known groups: Xanthoparmelia, Usnea, Parmotrema, and Hypotrachyna.

Clavulinaceae Family of fungi

The Clavulinaceae are a family of fungi in the order Cantharellales. The family is not well defined, but currently comprises species of clavarioid fungi as well as some corticioid fungi. These species are nutritionally diverse, some being ectomycorrhizal, others wood-rotting saprotrophs, others lichenized, and yet others lichenicolous.

Irwin M. Brodo 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. Irwin Brodo was honored in 1994 with an Acharius Medal presented to him by the International Association for Lichenology.

Lecanoraceae Family of fungi

The Lecanoraceae are a family of lichenized fungi in the order Lecanorales. Species of this family have a widespread distribution.

Ramalinaceae Family of fungi

The Ramalinaceae are a family of lichenized fungi in the order Lecanorales. The family name is synonymous with the name Bacidiaceae. Species of this family have a widespread distribution.

<i>Caloplaca</i> Genus of lichenised fungi in the family Teloschistaceae

Caloplaca is a lichen genus, composed of a number of distinct species. Members of the genus are commonly called firedot lichen, jewel lichen. gold lichens, "orange lichens", but they are not always orange, as in the case of C. albovariegata. The distribution of this lichen genus is worldwide, extending from Antarctica to the high Arctic. It includes a portion of northern North America and the Russian High Arctic. There are about thirty species of Caloplaca in the flora of the British Isles. An example species in this genus is Caloplaca saxicola, a lichen with worldwide distribution including the Antarctic continent, Europe and northern North America including the northern reaches of the Canadian boreal forests.

<i>Lecanora</i> Genus of lichenised fungi in the family Lecanoraceae

Lecanora is a genus of lichen commonly called rim lichens. Lichens in the genus Squamarina are also called rim lichens. Members of the genus have roughly circular fruiting discs (apothecia) with rims that have photosynthetic tissue similar to that of the nonfruiting part of the lichen body (thallus). Other lichens with apothecia having margins made of thallus-like tissue are called lecanorine.

<i>Xanthoria</i> Genus of lichenised fungi in the family Teloschistaceae

Xanthoria is a genus of lichenized fungi in the family Teloschistaceae. Common names include orange lichen, orange wall lichen, and sunburst lichen. They can be identified by their characteristic squamulose morphology with distinctive "fairy cups".

<i>Parmotrema</i> Genus of fungi

Parmotrema is a genus of lichen belonging to the family Parmeliaceae. It is a large genus, containing an estimated 300 species, with a centre of diversity in subtropical regions of South America and the Pacific Islands.

<i>Punctelia</i> Genus of lichen

Punctelia is a genus of foliose lichens belonging to the large family Parmeliaceae. The genus, which contains about 50 species, was segregated from genus Parmelia in 1982. Characteristics that define Punctelia include the presence of hook-like to thread-like conidia, simple rhizines, and point-like pseudocyphellae. It is this last feature that is alluded to in the common names speckled shield lichens or speckleback lichens.

<i>Xanthoparmelia</i> Genus of fungi

Xanthoparmelia is a genus of foliose lichen in the family Parmeliaceae. Xanthoparmelia is synonymous with Almbornia, Neofuscelia, Chondropsis, Namakwa, Paraparmelia, and Xanthomaculina. This genus of lichen is commonly found in the United States, as well as Australia, New Zealand and Ecuador.

<i>Rhizoplaca</i> Genus of fungi

Rhizoplaca is a genus of lichenized fungi in the family Lecanoraceae. Members of the genus are commonly called rimmed navel lichens because of their umbillicate growth form and lecanorine apothecia, also rock-posy lichen and rockbright. The genus has a widespread distribution and contains 11 species.

Dictyonema is a genus of mainly tropical basidiolichens in the family Hygrophoraceae.

Caliciaceae Family of lichen-forming fungi

The Caliciaceae are a family of mostly lichen-forming fungi belonging to the class Lecanoromycetes in the division Ascomycota. Although the family has had its classification changed several times throughout its taxonomic history, the use of modern molecular phylogenetic methods have helped to establish its current placement in the order Caliciales. Caliciaceae contains 36 genera and about 600 species. The largest genus is Buellia, with around 300 species; there are more than a dozen genera that contain only a single species.

<i>Menegazzia</i> Genus of fungi

Menegazzia is a genus of lichenized fungi containing roughly 70 accepted species. The group is sometimes referred to as the tree flutes, honeycombed lichens, or hole-punch lichens. The most obvious morphological feature of the genus is the distinctive perforations spread across the upper side of the thallus. This makes the group easy to recognise, even for those not particularly familiar with lichen identification.

John Walter Thomson Jr. (1913–2009) was a Scottish-born American botanist and lichenologist, sometimes referred to as the "Dean of North American Lichens".

Peter Wilfred James (1930–2014) was an English botanist and lichenologist. He was a pioneer in the study of lichens as "environmental indicators, especially in atmospheric pollution".
