Pertusaria Melanochlora
''Pertusaria'' is a large genus of warty crustose lichens in the Pertusariaceae family.Field Guide to California Lichens, Stephen Sharnoff, Yale University Press, 2014, The fruiting bodies are usually modified apothecia that immersed in warts on the main body (thallus) with small holes for the spores to emerge, similar to ostioles, or are fully above and lecanorine (spore bearing discs surrounded by a ring of tissue similar to the tissue of the thallus. Members of the genus are commonly called wart lichens. The widespread genus contains over 500 species. Classification in the large genus relies heavily on thallus chemistry to distinguish and classify species, some of which differ only in the presence or absence of a single secondary chemical. Lichexanthone Lichexanthone is an organic compound in the structural class of chemicals known as xanthones. Lichexanthone was first isolated and identified by Japanese chemists from a species of foliose lichen, leafy lichen in the ...

Pertusariales Genera
The Pertusariales are an order (biology), order of fungi in the class Lecanoromycetes, comprising 8 family (biology), families, 31 genera, and over 600 species, many of which form lichens. This diverse group is characterized by complex taxonomy (biology), taxonomic history and ongoing phylogenetic revisions. Originally proposed by Maurice Choisy in 1949 and later formally published by the lichenologists David L. Hawksworth and Ove Eriksson in 1986, Pertusariales has undergone significant reclassification due to molecular phylogenetics studies. The order includes well-known genera such as ''Pertusaria'' and ''Ochrolechia'', as well as families like Megasporaceae and Icmadophilaceae. Pertusariales species exhibit a wide range of morphology (biology), morphological features and ecological roles, from non-lichenized fungi to various forms of lichen symbioses. The order's taxonomy has been subject to considerable debate and revision, with recent research leading to the establishment o ...

Lichen Genera
A lichen ( , ) is a hybrid colony (biology), colony of algae or cyanobacteria living symbiotically among hypha, filaments of multiple fungus species, along with yeasts and bacteria embedded in the cortex or "skin", in a mutualism (biology), 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 nutrient cycling and producers which many higher trophic feeders feed on, such as reindeer, gastropods, nematodes, mites, and springtails. Lichens have properties different from those of their component organisms. They come in man ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pertusaria
''Pertusaria'' is a large genus of warty crustose lichen, crustose lichens in the Pertusariaceae family.Field Guide to California Lichens, Stephen Sharnoff, Yale University Press, 2014, The fruiting bodies are usually modified apothecia that immersed in warts on the main body (thallus) with small holes for the spores to emerge, similar to ostioles, or are fully above and lecanorine (spore bearing discs surrounded by a ring of tissue similar to the tissue of the thallus. Members of the genus are List of common names of lichen genera, commonly called wart lichens. The widespread genus contains over 500 species. Classification in the large genus relies heavily on thallus chemistry to distinguish and classify species, some of which differ only in the presence or absence of a single secondary metabolite, secondary chemical. Lichexanthone, norlichexanthone, and their chlorinated derivatives are common in this genus. Selected species * ''Pertusaria amara'' * ''Pertusaria californic ...

Pertusaria Lactea
''Pertusaria lactea'' is a species of warty crustose lichens in the Pertusariaceae The Pertusariaceae are a family of lichen-forming fungi in the order Pertusariales. Taxonomy The family was formally circumscribed by German lichenologist Gustav Wilhelm Körber in 1846. It contained the genera ''Pertusaria'' and ''Ochrolechia ... family. These lichens are white to cream or pale grey. They mainly can be found on northern exposed siliceous or calcareous rocks. This species is present in North America, Arctic, Europe, Asia and South Africa. References lactea Lichen species Taxa named by Carl Linnaeus Lichens of the Arctic {{Pertusariales-stub ...
