Pertusaria Rhodostoma

	Pertusaria Rhodostoma ''Pertusaria rhodostoma'' is a little-known species of bark-dwelling lichen in the family Pertusariaceae. Known only from historical collections made in Colombia, it is classified as data deficient in the IUCN Red List. Taxonomy ''Pertusaria rhodostoma'' was described as a new species by the Finnish lichenologist William Nylander. In the protologue, Nylander compared this species to '' Pertusaria leioplaca,'' noting its distinct rose-pink to rosy-scarlet ostioles, which are small and either slightly or barely sunken into the apothecia (fruiting bodies). The apothecia-bearing warts, measuring approximately 1 mm in diameter, are convex and relatively crowded on the lichen's surface. Most of these warts host a single apothecium, but some bear up to six. He noted the spores of ''P. rhodostoma'' to be transparent and elongated, measuring 50–74 μm in length and 25–34 μm in width. The thallus was described as rough and uneven, with a whitish to pale ash-gre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]

	Conservation Status The conservation status of a group of organisms (for instance, a species) indicates whether the group still exists and how likely the group is to become extinct in the near future. Many factors are taken into account when assessing conservation status: not simply the number of individuals remaining, but the overall increase or decrease in the population over time, breeding success rates, and known threats. Various systems of conservation status are in use at international, multi-country, national and local levels, as well as for consumer use such as sustainable seafood advisory lists and certification. The two international systems are by the International Union for Conservation of Nature (IUCN) and The Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES).

picture info	Lichens Described In 1863 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 ...

	Species Fungorum ''Index Fungorum'' is an international project to index all formal names (Binomial nomenclature, scientific names) in the fungus Kingdom (biology), kingdom. As of 2015, the project is based at the Royal Botanic Gardens, Kew, one of three partners along with Landcare Research New Zealand Limited, Landcare Research and the Institute of Microbiology, Chinese Academy of Sciences. It is somewhat comparable to the International Plant Names Index (IPNI), in which the Royal Botanic Gardens is also involved. A difference is that where IPNI does not indicate Correct name (botany), correct names, the ''Index Fungorum'' does indicate the status of a name. In the returns from the search page, a currently correct name is indicated in green, while others are in blue (a few, aberrant usages of names are indicated in red). All names are linked to pages giving the correct name, with lists of Synonym (taxonomy), synonyms. ''Index Fungorum'' is one of three nomenclatural repositories recognized b ...
