Verrucariaceae
The Verrucariaceae are a family of mostly lichenised fungi in the order Verrucariales. The lichen-forming species, which comprise the vast majority of the family, have a wide variety of thallus forms, and include crustose (crust-like), foliose (bushy), and squamulose (scaly) representatives. Several characteristics of the spore-bearing structures, the ascomata, define the family, including their perithecioid form–more or less spherical or flask-shaped, with a single opening and otherwise completely enclosed by a wall. Squamulose members of the Verrucariaceae with simple ascospores (lacking partitions called septa), and without algae in the spore-bearing region are known as lichens; there are more than 80 of these species. The family has several dozen lichenicolous (lichen-dwelling) examples, including a few genera that contain solely lichenicolous members. An unusually diverse variety of photobiont partners have been recorded, mostly green algae, but also brown algae and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Buoux
Buoux ju̟ːksis a commune in the Vaucluse department in the Provence-Alpes-Côte d'Azur region in southeastern France. Located on the north side of the Luberon, the town is known for the high cliffs that surround it, making it a popular venue for rock-climbing enthusiasts, as well as the ruins of a medieval fort that was built in the 13th century and destroyed in 1660. The town's population peaked in the mid 19th century with 244 inhabitants in 1836 before falling to only 44 people in 1961. The population has since rebounded some to 122 in 2006. Buoux has few industries, including tourism, with several bed-and-breakfasts and restaurants, and agriculture, with production of lavender, honey and truffles.

Cécile Gueidan
Cécile Gueidan is a mycologist and lichenologist who applies morphological and molecular biological methods to the origin and taxonomy of fungi that live in lichen symbioses and within rocks. Early life and education Gueidan began working on lichens during her Maitrise (1998) and DEA (1999) qualifications from Université Louis Pasteur and National Museum of Natural History, France. This included practical fieldwork experience with Claude Roux. She then studied molecular methods for lichen taxonomy at Duke University, USA and applied them to pyrenocarpous and Verrucariaceae lichens. Through combining morphological and molecular characters, she was able to refine the taxonomy of these groups. She was awarded her doctorate for this research in 2007. Career Her research focuses on the evolution and taxonomy of lichenised fungi and other ascomycete fungi. After gaining her doctorate, Gueidan carried out research at the Westerdijk Institute in the Netherlands on relationships be ...

Claude Roux
Claude Roux is a French lichenologist, mycologist and Esperantist. He has co-authored books about the identification of lichens written in Esperanto. Career Between 1969 and 1975 Roux was employed as a biology and geology teacher in a secondary school. From 1975 he worked at the Botany Laboratory of the CNRS Mediterranean Institute of Ecology and Paleoecology in Marseille, studying systematics, morphology and reproduction of lichens. He retired in 2005 but continues scientific research as a honorary CNRS researcher. He has been president of the French Institute of Esperanto. He is a member of the International Academy of Sciences San Marino The International Academy of Sciences San Marino ( eo, Akademio Internacia de la Sciencoj San Marino, AIS) was a scientific association.

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 ...

Crustose Lichen
Crustose lichens are lichens that form a crust which strongly adheres to the Substrate (biology), substrate (soil, rock, tree bark, etc.), making separation from the substrate impossible without destruction. The basic structure of crustose lichens consists of a cortex (botany), cortex layer, an algal layer, and a medulla. The upper cortex layer is differentiated and is usually pigmented. The algal layer lies beneath the cortex. The medulla fastens the lichen to the substrate and is made up of Fungus, fungal hyphae. The surface of crustose lichens is characterized by branching cracks that periodically close in response to climatic variations such as alternate wetting and drying regimes. Subtypes * Powdery – considered as the simplest subtype due to the absence of an organized thallus. :The thallus appears powdery. :E.g. Genera ''Lepraria'', ''Vezdaea'' * Endolithic – grows inside the rock, usually in interstitial spaces between mineral grains. The :upper cortex is usually d ...

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 ...

Type Species
In zoological nomenclature, a type species (''species typica'') is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically associated, i.e., the species that contains the biological type specimen(s). Article 67.1 A similar concept is used for suprageneric groups and called a type genus. In botanical nomenclature, these terms have no formal standing under the code of nomenclature, but are sometimes borrowed from zoological nomenclature. In botany, the type of a genus name is a specimen (or, rarely, an illustration) which is also the type of a species name. The species name that has that type can also be referred to as the type of the genus name. Names of genus and family ranks, the various subdivisions of those ranks, and some higher-rank names based on genus names, have such types.

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 .
