Sarcodon Quercinofibulatus
''Sarcodon quercinofibulatus'' is a species of tooth fungus in the family Bankeraceae. Its specific name reflects both its ecological association with oak trees (''Quercus'') and the distinctive presence of clamp connections on its hyphae, which distinguishes it from related European species. The fungus produces brownish-grey scaled caps 6–14 cm broad with short cream to grey-brown spines underneath and is strictly ectomycorrhizal with sessile oak, downy oak, and European beech. Known only from northeastern Catalonia in Spain, it fruits on the forest floor of deciduous woodlands during summer and early autumn at elevations between 400–1000 metres. Taxonomy ''Sarcodon quercinofibulatum'' was recognised as new to science in 2011 by Pérez‑De‑Gregorio, Macau, and Carbó. The specific epithet derives from ''Quercus'' ("oak") and the Latin ("with clamps"), reflecting its ecology and the pervasive presence of clamp connections on its hyphae. The holotype specimen was c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tooth Fungus
The hydnoid fungi are a group of fungi in the Basidiomycota with basidiocarps (fruit bodies) producing spores on pendant, tooth-like or spine-like projections. They are colloquially called tooth fungi. Originally such fungi were referred to the genus ''Hydnum'' ("hydnoid" means ''Hydnum''-like), but it is now known that not all hydnoid species are closely related. History ''Hydnum'' was one of the original genera created by Linnaeus in his ''Species Plantarum'' of 1753. It contained all species of fungi with fruit bodies bearing pendant, tooth-like projections. Subsequent authors described around 900 species in the genus. With increasing use of the microscope, it became clear that not all tooth fungi were closely related and most ''Hydnum'' species were gradually moved to other genera. The Dutch mycologist Rudolph Arnold Maas Geesteranus paid particular attention to the group, producing a series of papers reviewing the taxonomy of hydnoid fungi. The original genus ''Hydnum'' is s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sarcodon Imbricatus
''Sarcodon imbricatus'', commonly known as the shingled hedgehog or scaly hedgehog, is a species of tooth fungus in the order Thelephorales. The mushroom has a large, brownish cap with large brown scales and may reach 30 cm (12 in) in diameter. On the underside it sports greyish, brittle teeth instead of gills, and has white flesh. Its spore print is brown. It ranges throughout Europe and North America, while collections from the British Isles are now assigned to '' Sarcodon squamosus''. It appears in autumn and is associated with spruce (''Picea''). The mushroom is edible, but it may be bitter and possibly causes gastrointestinal upset. Taxonomy The Swedish botanist Olof Celsius reported in 1732 that ''Sarcodon imbricatus'' occurred in the vicinity of Uppsala, and Carl Linnaeus wrote of it in his 1737 work ''Flora lapponica''. It was one of the species initially described by Linnaeus, as ''Hydnum imbricatum'', in the second volume of his ''Species Plantarum'' in 1753 ...

Phylogenetic
In biology, phylogenetics () is the study of the evolutionary history of life using observable characteristics of organisms (or genes), which is known as phylogenetic inference. It infers the relationship among organisms based on empirical data and observed heritable traits of DNA sequences, protein amino acid sequences, and morphology. The results are a phylogenetic tree—a diagram depicting the hypothetical relationships among the organisms, reflecting their inferred evolutionary history. The tips of a phylogenetic tree represent the observed entities, which can be living taxa or fossils. A phylogenetic diagram can be rooted or unrooted. A rooted tree diagram indicates the hypothetical common ancestor of the taxa represented on the tree. An unrooted tree diagram (a network) makes no assumption about directionality of character state transformation, and does not show the origin or "root" of the taxa in question. In addition to their use for inferring phylogenetic pa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rudolf Arnold Maas Geesteranus
Rudolf Arnold Maas Geesteranus (20 January 1911 in The Hague – 18 May 2003 in Oegstgeest), was a Dutch mycologist whose work on both ascomycetes and basidiomycetes helped to refine fungal taxonomy over a career of nearly six decades. Early life and education Maas Geesteranus was born in The Hague, but spent his childhood (from infancy until age 18) in the Dutch East Indies, where his family emigrated shortly after his birth. Upon returning to the Netherlands in 1929, he completed secondary school in The Hague and enrolled at Leiden University to study biology. While still a student, he joined the staff of the Rijksherbarium (the National Herbarium of the Netherlands) as a volunteer assistant—a post that proved pivotal in launching his scientific career. In mid‑1939, at 28, he was promoted to assistant, becoming the sole mycologist on the herbarium staff at that time. Life and career During the German occupation of the Netherlands in World War II, Maas Geesteranus conti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Section (botany)
In botany, a section () is a taxonomic rank below the genus, but above the species. The subgenus, if present, is higher than the section; and the rank of Series (botany), series, if present, is below the section. Sections may in turn be divided into subsections.Article 4 in Sections are typically used to help organise very large genera, which may have hundreds of species. A botanist wanting to distinguish groups of species may prefer to create a taxon at the rank of section or series to avoid making combinatio nova, new combinations, i.e. many new Binomial nomenclature, binomial names for the species involved. Examples: * ''Lilium'' sectio ''Martagon'' Rchb. are the Turks' cap lilies * ''Plagiochila aerea'' Taylor is the type species of ''Plagiochila'' sect.

Sarcodon Aspratus
''Sarcodon'' is a genus of fungi in the family Bankeraceae, which is part of the order Thelephorales, known for its almost universal ectomycorrhizal ecology. The genus owes its name to the presence of teeth-like spines on the hymenophore, from ancient Greek; ''sarco'' = flesh and ''odon'' = tooth. For this reason they are commonly called "tooth fungi", or "Hydnoid fungi". Description ''Sarcodon'' species have yellow to brown tinted basidiospores, with lengths in the range of 7.4–9 μm. The basidiomata are often soft and fleshy. Species , Index Fungorum listed 49 valid species of ''Sarcodon''. However, in 2019 Larsson ''et al.'' transferred 12 species into the genus ''Hydnellum''. In 2024, Douch ''et al.'' transferred '' Sarcodon carbonarius'' to the genus '' Neosarcodon''. * '' Sarcodon aglaosoma'' * ''Sarcodon atroviridis'' * ''Sarcodon austrofibulatus'' * ''Sarcodon bubalinus'' * '' Sarcodon caliginosus'' * ''Sarcodon calvatus'' * ''Sarcodon catalaunicus'' * ''Sar ...

Clade
In biology, a clade (), also known as a Monophyly, monophyletic group or natural group, is a group of organisms that is composed of a common ancestor and all of its descendants. Clades are the fundamental unit of cladistics, a modern approach to taxonomy adopted by most biological fields. The common ancestor may be an individual, a population, or a species (extinct or Extant taxon, extant). Clades are nested, one in another, as each branch in turn splits into smaller branches. These splits reflect evolutionary history as populations diverged and evolved independently. Clades are termed ''monophyletic'' (Greek: "one clan") groups. Over the last few decades, the cladistic approach has revolutionized biological classification and revealed surprising evolutionary relationships among organisms. Increasingly, taxonomists try to avoid naming Taxon, taxa that are not clades; that is, taxa that are not Monophyly, monophyletic. Some of the relationships between organisms that the molecul ...

Sister Group
In phylogenetics, a sister group or sister taxon, also called an adelphotaxon, comprises the closest relative(s) of another given unit in an evolutionary tree. Definition The expression is most easily illustrated by a cladogram: Taxon A and taxon B are sister groups to each other. Taxa A and B, together with any other extant or extinct descendants of their most recent common ancestor (MRCA), form a monophyletic group, the clade AB. Clade AB and taxon C are also sister groups. Taxa A, B, and C, together with all other descendants of their MRCA form the clade ABC. The whole clade ABC is itself a subtree of a larger tree which offers yet more sister group relationships, both among the leaves and among larger, more deeply rooted clades. The tree structure shown connects through its root to the rest of the universal tree of life. In cladistic standards, taxa A, B, and C may represent specimens, species, genera, or any other taxonomic units. If A and B are at the same taxono ...

Monophyletic
In biological cladistics for the classification of organisms, monophyly is the condition of a taxonomic grouping being a clade – that is, a grouping of organisms which meets these criteria: # the grouping contains its own most recent common ancestor (or more precisely an ancestral population), i.e. excludes non-descendants of that common ancestor # the grouping contains all the descendants of that common ancestor, without exception Monophyly is contrasted with paraphyly and polyphyly as shown in the second diagram. A ''paraphyletic'' grouping meets 1. but not 2., thus consisting of the descendants of a common ancestor, excepting one or more monophyletic subgroups. A '' polyphyletic'' grouping meets neither criterion, and instead serves to characterize convergent relationships of biological features rather than genetic relationships – for example, night-active primates, fruit trees, or aquatic insects. As such, these characteristic features of a polyphyletic grouping ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Castanea Sativa
The sweet chestnut (''Castanea sativa''), also known as the Spanish chestnut or European chestnut, is a species of tree in the family Fagaceae, native to Southern Europe and Asia Minor, and widely cultivated throughout the Temperate climate, temperate world. A substantial, long-lived deciduous tree, it produces an edible seed, the chestnut, which has been used in cooking since ancient times. Description ''Castanea sativa'' attains a height of with a trunk often in diameter. Around 20 trees are recorded with diameters over including one in diameter at breast height. A famous ancient tree known as the Hundred Horse Chestnut in Sicily was historically recorded at in diameter (although it has split into multiple trunks above ground). The bark often has a net-shaped (retiform) pattern with deep furrows or fissures running spirally in both directions up the trunk. The trunk is mostly straight with branching starting at low heights.

Species Complex
In biology, a species complex is a group of closely related organisms that are so similar in appearance and other features that the boundaries between them are often unclear. The taxa in the complex may be able to hybridize readily with each other, further blurring any distinctions. Terms that are sometimes used synonymously but have more precise meanings are cryptic species for two or more species hidden under one species name, sibling species for two (or more) species that are each other's closest relative, and species flock for a group of closely related species that live in the same habitat. As informal taxonomic ranks, species group, species aggregate, macrospecies, and superspecies are also in use. Two or more taxa that were once considered conspecific (of the same species) may later be subdivided into infraspecific taxa (taxa within a species, such as plant variety (botany), varieties), which may be a complex ranking but it is not a species complex. In most cases, a specie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
