''Candelariaceae'' is a family of lichen-forming fungi in the order Candelariales. It contains seven genera and about 73 species. The family was circumscribed by Finnish lichenologist Rainar Hakulinen in 1954 to contain the type genus In biological taxonomy, the type genus is the genus which defines a biological family and the root of the family name.

Candelariella Xanthostigma
''Candelariella'' is a genus of bright yellow, ocher, or greenish yellow crustose or squamulose lichens in the family Candelariaceae. Members of the genus are commonly called eggyolk lichens, goldspeck lichens, or yolk lichens. The genus was circumscribed in 1894 by Swiss lichenologist Johannes Müller Argoviensis, with '' Candelariella vitellina'' assigned as the type species. Characteristics The key feature of ''Candelariella'' species are the distinct yellow apothecia. Although all species are very small, even the smallest can be identified by the lemon-yellow to orange-yellow discs. Most species have a yellow thallus, although '' Candelariella antennaria'' is one example with a grey thallus. Some species are pycnidiate. This genus will generally have all spot tests emerge as negative, although K tests may have an orange or reddish colour on some species' apothecia. Spore count between species varies from 8 to 32 simply or thinly septate spores. Spores often hold one to t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rainar Hakulinen
Rainar Alarik Hakulinen (9 October 1918 – 29 December 1991) was a Finnish lichenologist and schoolteacher. He was noted as an expert on the lichen family Candelariaceae, and was known for his numerous phytogeographical publications about the boreal and arctic lichens of Finland, Northern Norway, and Russian Karelia. Biography Hakulinen was born in on 9 October 1918. At the time, this area was part of Finland, but is now in the Republic of Karelia, a part of Russia. Hakulinen served in the Finnish Army in its war against Russia in 1941–1944, spending a lot of his time there on the frontier at the Svir River. He spent several months in military hospitals to heal his wounds. In his school years, Hakulinen knew the lichenologist Veli Räsänen, who encouraged his early interest in lichens. Räsäsen had lived in the area for years and had studied its lichen flora quite thoroughly; Hakulinen accompanied him on field trips. Hakulinen maintained his interest after entering the ...

Ascomycota Families
Ascomycota is a phylum of the kingdom Fungi that, together with the Basidiomycota, forms the subkingdom Dikarya. Its members are commonly known as the sac fungi or ascomycetes. It is the largest phylum of Fungi, with over 64,000 species. The defining feature of this fungal group is the " ascus" (), a microscopic sexual structure in which nonmotile spores, called ascospores, are formed. However, some species of the Ascomycota are asexual, meaning that they do not have a sexual cycle and thus do not form asci or ascospores. Familiar examples of sac fungi include morels, truffles, brewers' and bakers' yeast, dead man's fingers, and cup fungi. The fungal symbionts in the majority of lichens (loosely termed "ascolichens") such as ''Cladonia'' belong to the Ascomycota. Ascomycota is a monophyletic group (it contains all descendants of one common ancestor). Previously placed in the Deuteromycota along with asexual species from other fungal taxa, asexual (or anamorphic) ascom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lichen Families
A lichen ( , ) is a composite organism that arises from algae or cyanobacteria living among filaments of multiple fungi species in a mutualistic relationship.Introduction to Lichens – An Alliance between Kingdoms .

They come in many colors, sizes, and forms and are sometimes plant-like, but are not s. They may have tiny, leafless branches (); flat leaf-like structures ( |
Type Genus
In biological taxonomy, the type genus is the genus which defines a biological family and the root of the family name. Zoological nomenclature According to the International Code of Zoological Nomenclature, "The name-bearing type of a nominal family-group taxon is a nominal genus called the 'type genus'; the family-group name is based upon that of the type genus." Any family-group name must have a type genus (and any genus-group name must have a type species, but any species-group name may, but need not, have one or more type specimens). The type genus for a family-group name is also the genus that provided the stem to which was added the ending -idae (for families). :Example: The family name Formicidae has as its type genus the genus ''Formica'' Linnaeus, 1758. Botanical nomenclature In botanical nomenclature, the phrase "type genus" is used, unofficially, as a term of convenience. In the '' ICN'' this phrase has no status. The code uses type specimens for ranks up to fam ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Circumscription (taxonomy)
In biological taxonomy, circumscription is the content of a taxon, that is, the delimitation of which subordinate taxa are parts of that taxon. If we determine that species X, Y, and Z belong in Genus A, and species T, U, V, and W belong in Genus B, those are our circumscriptions of those two genera. Another systematist might determine that T, U, V, W, X, Y, and Z all belong in genus A. Agreement on circumscriptions is not governed by the Codes of Zoological or Botanical Nomenclature, and must be reached by scientific consensus. A goal of biological taxonomy is to achieve a stable circumscription for every taxon. This goal conflicts, at times, with the goal of achieving a natural classification that reflects the evolutionary history of divergence of groups of organisms. Balancing these two goals is a work in progress, and the circumscriptions of many taxa that had been regarded as stable for decades are in upheaval in the light of rapid developments in molecular phylogenetics ...

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...
