Morchella Dunensis
''Morchella dunensis'', the morel of the dunes, is a species of fungus in the family ''Morchellaceae'' (Ascomycota). It was first described as a form of ''Morchella esculenta'' by Castañera and colleagues in 1996, but was later recombined as a distinct species by Clowez.Clowez P. (1997). ''Morchella dunensis'' (Boud.) Clowez (stat. et comb. nov. ad int.). Une bonne espèce pour un mystère nomenclatural. Documents Mycologiques 26(104):13–20. In a 2014 study by Richard and colleagues, the authors concluded that the taxon was conspecific to ''Morchella vulgaris'', due to its close phylogenetic proximity to the latter. However, following increased molecular sampling and the testing of an isoparatype collection by Loizides and colleagues in 2016, it was revealed that ''M. dunensis'' is indeed very closely related to, but phylogenetically distinct from ''M. vulgaris''. This study also showed that the taxon '' Morchella andalusiae'' is phylogenetically identical and therefore a later ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plouharnel
Plouharnel (; ) is a commune in the Morbihan department of Brittany in north-western France. Inhabitants of Plouharnel are called in French ''Plouharnelais''. Geography Plouharnel is a seaside town located in the south of Morbihan, southwest of Auray, southeast of Lorient and west of Vannes. The commune is border by Atlantic ocean except to the north and the east. The northern part of the isthmus connecting the mainland to the ancient island of Quiberon is located in the commune's southern part. Map Transports There are two railway stations in the commune of Plouharnel, both on the Auray–Quiberon railway which is operated in summer only: Plouharnel-Carnac and Les Sables-Blancs. At Auray station connections to Paris and other places in France are offered. Monuments The commune contains a number of megalithic monuments including those at Le Vieux-Moulin, comprising six stones weighing up to ten tons.

Morchella Vulgaris
''Morchella vulgaris'' is a widespread fungus of the family Morchellaceae ( Ascomycota). It was originally described in 1801 as a form of the common yellow morel ('' Morchella esculenta'') by mycologist Christiaan Hendrik Persoon, but was later recombined as a distinct species by Samuel Gray. Owing to its high morphological plasticity, its taxonomical status had long been in flux, sometimes treated as a variety of, or conspecific to '' Morchella esculenta'',Dennis RWG. (1978). Bristish Ascomycètes. Ed. Cramer, Vaduz. p. 585. while at the same time several forms and varieties of ''M. vulgaris'' itself have been described. An extensive phylogenetic and nomenclatural study by Richard and colleagues in 2014, confirmed the status of ''Morchella vulgaris'' as a distinct species, and resolved several of its synonymities. This species is characterised by the predominantly grey colours of its cap A cap is a flat headgear, usually with a visor. Caps have crowns that fit very close ...

Fungi Described In 1996
A fungus (plural, : fungi or funguses) is any member of the group of Eukaryote, eukaryotic organisms that includes microorganisms such as yeasts and Mold (fungus), molds, as well as the more familiar mushrooms. These organisms are classified as a Kingdom (biology), kingdom, separately from the other eukaryotic kingdoms, which by one traditional classification include Plantae, Animalia, Protozoa, and Chromista. A characteristic that places fungi in a different kingdom from plants, bacteria, and some protists is chitin in their cell walls. Fungi, like animals, are heterotrophs; they acquire their food by absorbing dissolved molecules, typically by secreting digestive enzymes into their environment. Fungi do not photosynthesize. Growth is their means of motility, mobility, except for spores (a few of which are flagellated), which may travel through the air or water. Fungi are the principal decomposers in ecological systems. These and other differences place fungi in a single gro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dune
A dune is a landform composed of wind- or water-driven sand. It typically takes the form of a mound, ridge, or hill. An area with dunes is called a dune system or a dune complex. A large dune complex is called a dune field, while broad, flat regions covered with wind-swept sand or dunes with little or no vegetation are called ''ergs'' or ''sand seas''. Dunes occur in different shapes and sizes, but most kinds of dunes are longer on the stoss (upflow) side, where the sand is pushed up the dune, and have a shorter ''slip face'' in the lee side. The valley or trough between dunes is called a ''dune slack''. Dunes are most common in desert environments, where the lack of moisture hinders the growth of vegetation that would otherwise interfere with the development of dunes. However, sand deposits are not restricted to deserts, and dunes are also found along sea shores, along streams in semiarid climates, in areas of glacial outwash, and in other areas where poorly cemented sa ...

Mediterranean
The Mediterranean Sea is a sea connected to the Atlantic Ocean, surrounded by the Mediterranean Basin and almost completely enclosed by land: on the north by Western and Southern Europe and Anatolia, on the south by North Africa, and on the east by the Levant. The Sea has played a central role in the history of Western civilization. Geological evidence indicates that around 5.9 million years ago, the Mediterranean was cut off from the Atlantic and was partly or completely desiccated over a period of some 600,000 years during the Messinian salinity crisis before being refilled by the Zanclean flood about 5.3 million years ago. The Mediterranean Sea covers an area of about , representing 0.7% of the global ocean surface, but its connection to the Atlantic via the Strait of Gibraltar—the narrow strait that connects the Atlantic Ocean to the Mediterranean Sea and separates the Iberian Peninsula in Europe from Morocco in Africa—is only wide. The Mediterranean Sea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Xerophile
A xerophile () is an extremophilic organism that can grow and reproduce in conditions with a low availability of water, also known as water activity. Water activity (aw) is measured as the humidity above a substance relative to the humidity above pure water (Aw = 1.0). Xerophiles are "xerotolerant", meaning tolerant of dry conditions. They can often survive in environments with water activity below 0.8; above which is typical for most life on Earth. Typically xerotolerance is used with respect to matric drying, where a substance has a low water concentration. These environments include arid desert soils. The term osmotolerance is typically applied to organisms that can grow in solutions with high solute concentrations (salts, sugars), such as halophiles. The common food preservation method of reducing water (food drying) activities may not prevent the growth of xerophilic organisms, often resulting in food spoilage. Some mold and yeast species are xerophilic. Mold growth on bre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Morchella Andalusiae
''Morchella'', the true morels, is a genus of edible sac fungi closely related to anatomically simpler cup fungi in the order Pezizales (division Ascomycota). These distinctive fungi have a honeycomb appearance due to the network of ridges with pits composing their caps. Morels are prized by gourmet cooks, particularly in Catalan and French cuisine. Due to difficulties in cultivation, commercial harvesting of wild morels has become a multimillion-dollar industry in the temperate Northern Hemisphere, in particular North America, Turkey, China, the Himalayas, India, and Pakistan where these highly prized fungi are found in abundance. Typified by ''Morchella esculenta'' in 1794, the genus has been the source of considerable taxonomical controversy throughout the years, mostly with regard to the number of species involved, with some mycologists recognising as few as three species and others over thirty. Current molecular phylogenetics suggest there might be over seventy species of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phylogenetically
In biology, phylogenetics (; from Greek φυλή/ φῦλον [] "tribe, clan, race", and wikt:γενετικός, γενετικός [] "origin, source, birth") is the study of the evolutionary history and relationships among or within groups of organisms. These relationships are determined by Computational phylogenetics, phylogenetic inference methods that focus on observed heritable traits, such as DNA sequences, protein amino acid sequences, or morphology. The result of such an analysis is a phylogenetic tree—a diagram containing a hypothesis of relationships that reflects the evolutionary history of a group of organisms. The tips of a phylogenetic tree can be living taxa or fossils, and represent the "end" or the present time in an evolutionary lineage. A phylogenetic diagram can be rooted or unrooted. A rooted tree diagram indicates the hypothetical common ancestor of the tree. An unrooted tree diagram (a network) makes no assumption about the ancestral line, and does n ...

Molecular
A molecule is a group of two or more atoms held together by attractive forces known as chemical bonds; depending on context, the term may or may not include ions which satisfy this criterion. In quantum physics, organic chemistry, and biochemistry, the distinction from ions is dropped and ''molecule'' is often used when referring to polyatomic ions. A molecule may be homonuclear, that is, it consists of atoms of one chemical element, e.g. two atoms in the oxygen molecule (O2); or it may be heteronuclear, a chemical compound composed of more than one element, e.g. water (molecule), water (two hydrogen atoms and one oxygen atom; H2O). In the kinetic theory of gases, the term ''molecule'' is often used for any gaseous particle regardless of its composition. This relaxes the requirement that a molecule contains two or more atoms, since the noble gases are individual atoms. Atoms and complexes connected by non-covalent interactions, such as hydrogen bonds or ionic bonds, are typic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Morchella Esculenta
''Morchella esculenta'', (commonly known as common morel, morel, yellow morel, true morel, morel mushroom, and sponge morel) is a species of fungus in the family Morchellaceae of the Ascomycota. It is one of the most readily recognized of all the edible mushrooms and highly sought after. Each Ascocarp, fruit body begins as a tightly compressed, grayish sponge with lighter ridges, and expands to form a large yellowish sponge with large pits and ridges raised on a large white stipe (mycology), stem. The pitted yellow-brown pileus (mycology), caps measure broad by tall, and are fused to the stem at its lower margin, forming a continuous hollow. The pits are rounded and irregularly arranged. The hollow stem is typically long by thick, and white to yellow. The fungus fruits under hardwoods and conifers during a short period in the spring, depending on the weather, and is also associated with old orchards, woods and disturbed grounds. Taxonomy and naming The fungus was originally n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Form (botany)
In botanical nomenclature, a ''form'' (''forma'', plural ''formae'') is one of the "secondary" taxonomic ranks, below that of variety, which in turn is below that of species; it is an infraspecific taxon. If more than three ranks are listed in describing a taxon, the "classification" is being specified, but only three parts make up the "name" of the taxon: a genus name, a specific epithet, and an infraspecific epithet. The abbreviation "f." or the full "forma" should be put before the infraspecific epithet to indicate the rank. It is not italicised. For example: * '' Acanthocalycium spiniflorum'' f. ''klimpelianum'' or ** ''Acanthocalycium spiniflorum'' forma ''klimpelianum'' (Weidlich & Werderm.) Donald * ''Crataegus aestivalis'' (Walter) Torr. & A.Gray var. ''cerasoides'' Sarg. f. ''luculenta'' Sarg. is a classification of a plant whose name is: ** ''Crataegus aestivalis'' (Walter) Torr. & A.Gray f. ''luculenta'' Sarg. A form usually designates a group with a noticeable mor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
