Podaxis Microporus
''Podaxis'' is a genus of secotioid fungi in the family Agaricaceae. Species, which have the appearance of a "stalked-puffball", have a worldwide distribution, and tend to be found growing solitary or scattered on sandy soils, especially in arid regions. Although close to 50 species have been described, it has been argued that many of them may represent extremes in the natural range of variations found in ''Podaxis pistillaris''. Description Fruiting bodies have the appearance of an unopened '' Coprinus comatus'', with a stipe and a loose, brown to blackish powdery gleba at maturity. Basidiospores are obovate, thick-walled with a large apical pore, and typically 10-17 x 9-12 μm in size. Clamp connections are present. ''Podaxis'' is a common inhabitant of soil and termite mounds throughout the drier regions of the tropics and subtropics of the world. '' P. pistillaris'' is a ground-inhabiting species, but most ''Podaxis'' species in the rest of the world are associated with ter ...

Podaxis Pistillaris
''Podaxis pistillaris'' is a xerophile, xerophilic Agaricaceae, agaric mushroom related to the puffballs and Coprinus, inkcaps. It is commonly known as the desert shaggy mane. It grows to 11 cm tall and thrives in deserts and semi-deserts of North America, Australia, and South Africa. Taxonomy Older synonyms for this species include ''Lycoperdon pistillare'' L. (1771) and ''Scleroderma pistillare'' (L.) Pers. (1801). The species' common name stems from its superficial resemblance to the shaggy mane, ''Coprinus comatus'', the deliquescing gills of which it lacks. Description The pod grows up to tall. It has a hard, woody Plant stem, stem. The large cap, which protects the blackish spore-bearing tissue, splits, and usually falls away at maturity, allowing the spores to be dispersed by wind. The spore print is dark brown to black. The spores are usually 10–14 (–16) by (8–) 9–12 μm broadly oval to sub-globose, smooth yellow to deep reddish-brown with a do ...

Elias Magnus Fries
Elias Magnus Fries (15 August 1794 – 8 February 1878) was a Swedish mycologist and botanist. He is sometimes called the Mycology, "Linnaeus of Mycology". In his works he described and assigned botanical names to hundreds of fungus and lichen species, many of which remain authoritative today. Career Fries was born at Femsjö (Hylte Municipality), Småland, the son of the pastor there. He attended school in Växjö. He acquired an extensive knowledge of flowering plants from his father. In 1811 Fries entered Lund University where he studied under Carl Adolph Agardh and Anders Jahan Retzius. He obtained his doctorate in 1814. In the same year he was appointed an associate professorship in botany. Fries edited several exsiccata series, the first starting in 1818 under the title ''Lichenes Sveciae exsiccati, curante Elia Fries'' and the last together with Franz Joseph Lagger under the title ''Hieracia europaea exsiccata''. He was elected a member of the Royal Swedish Academ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Index Fungorum
''Index Fungorum'' is an international project to index all formal names (scientific names) in the fungus kingdom. As of 2015, the project is based at the Royal Botanic Gardens, Kew, one of three partners along with 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 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 synonyms. ''Index Fungorum'' is one of three nomenclatural repositories recognized by the Nomenclature Committee for Fungi; the others are '' MycoBank'' and '' Fungal Names''. As of 2023, over a millio ...

Leucocoprinus
''Leucocoprinus'' is a genus of fungi in the family Agaricaceae. Its best-known member is the distinctive yellow mushroom ''Leucocoprinus birnbaumii'', which is found in plant pots and greenhouses worldwide. The type species is ''Leucocoprinus cepistipes''. The genus has a widespread distribution and contains over 80 recognised species, however many of these species are very scarcely recorded and little known with only a small number of ''Leucocoprinus'' species which are commonly observed. The majority of the species in this genus are exclusive to tropical environments however numerous species have become a common sight in plant pots and greenhouses resulting in them becoming well known worldwide. Taxonomy The genus was created in 1888 by the French mycologist Narcisse Théophile Patouillard. Due to the superficially similar features which many ''Leucocoprinus'', ''Leucoagaricus'' and ''Lepiota'' species have these genera and the species within them have been subject to a grea ...

Agaricus Pocillator
''Agaricus pocillator'', a woodland mushroom, is distributed through southeastern North America in ranges at least as far north as Illinois. It can be distinguished in the field by its dark center, its small, bulbous base, which stains yellow, and its relatively slight stature. It is very similar to '' Agaricus placomyces'', but is a slightly smaller mushroom with a scalier cap and a more northern range within the United States. ''A. pocillator'' is inedible, and several other yellow-staining ''Agaricus'' species are poisonous. Hikers are often warned to avoid eating it when spotted. Ecology They are saprobic, meaning that they survive by decomposing dead or decaying organic material. They often grow alone or gregariously under hardwoods and in mixed woods throughout the southeast of North America. Description Their cap is 3–10 cm, convex to broadly convex or nearly flat in age, sometimes with an obscure, darker bump, and dry. The top is mainly whitish to dingy, developin ...

Montagnea Arenaria
''Montagnea arenaria'', commonly known as the gasteroid coprinus, is a species of secotioid fungus in the family Agaricaceae. Originally named ''Agaricus arenarius'' by Augustin Pyramus de Candolle in 1815, it was transferred to the genus '' Montagnea'' by Sanford Myron Zeller in 1943. The species is characterized by a cap that has an apical disc up to wide, radial gills, a hymenophore, and spores with a prominent germ pore A germ pore is a small pore in the outer wall of a fungal spore through which the germ tube exits upon germination. It can be wikt:apical, apical or eccentric in its location, and, on light microscopy, may be visualized as a lighter coloured are .... It is inedible.

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 ...

Ribosomal DNA
The ribosomal DNA (rDNA) consists of a group of ribosomal RNA encoding genes and related regulatory elements, and is widespread in similar configuration in all domains of life. The ribosomal DNA encodes the non-coding ribosomal RNA, integral structural elements in the assembly of ribosomes, its importance making it the most abundant section of RNA found in cells of eukaryotes. Additionally, these segments include regulatory sections, such as a promoter specific to the RNA polymerase I, as well as both transcribed and non-transcribed spacer segments. Due to their high importance in the assembly of ribosomes for protein biosynthesis, the rDNA genes are generally highly conserved in molecular evolution. The number of copies can vary considerably per species. Ribosomal DNA is widely used for phylogenetic studies. Structure The ribosomal DNA includes all genes coding for the non-coding structural ribosomal RNA molecules. Across all domains of life, these are the structural ...
