Pachykytospora
''Pachykytospora'' is a small genus of polypore, poroid fungi in the family Polyporaceae. Species in the cosmopolitan distribution, cosmopolitan genus cause white rot. There are about 10 species in the genus, with newest member described from European Russia in 2007. ''Pachykytospora'' species have fruit bodies that are resupination#Examples in fungi, resupinate (growing flat on the substrate (biology), substrate surface), with light brown tubes. They are characterized by their uneven, ellipsoid spores, and the ''Polyporus''-like skeletal-binding hyphae. Taxonomy The genus was circumscribed by Czech mycologists František Kotlaba and Zdenek Pouzar in 1963. The type species, ''Pachykytospora tuberculosa, P. tuberculosa'', was originally described as ''Boletus tuberculosus'' by Augustin Pyramus de Candolle in 1815. Species originally described as a member of ''Pachykytospora'' but later transferred to other genera include: ''Megasporoporia major, Pachykytospora major'' G.Y.Zhen ...

Pachykytospora Tuberculosa
''Pachykytospora tuberculosa'' is a species of poroid fungus in the family Polyporaceae, and the type species of genus ''Pachykytospora''. Taxonomy The genus ''Pachykytospora'' was circumscribed by Czech mycologists František Kotlaba František Kotlaba (20 May 1927 in Vlastiboř – 11 June 2020 in Prague) was a Czech botanist and mycologist. Scientific career After his degree in Natural Sciences and Pedagogy at the Charles University in Prague, Kotlaba received a post at ... and Zdenek Pouzar in 1963 with ''P. tuberculosa'' as the type species. This fungus was originally described as ''Boletus tuberculosus'' by Augustin Pyramus de Candolle in 1815. Elias Fries later (1821) sanctioned the name as ''Polyporus tuberculosus''. Habitat and distribution ''P. tuberculosa'', is known from Europe, Asia, and North America. In Europe it fruits almost exclusively on oak.

Haploporus (fungus)
''Haploporus'' is a genus of poroid fungi in the family Polyporaceae. Taxonomy The genus ''Haploporus'' was circumscribed by mycologists Appollinaris Semenovich Bondartsev and Rolf Singer in 1944 with '' Haploporus odorus'' as the type, and only species. The name ''Haploporus'' is derived from the Greek words ("simple"), and ("pore"). Yu-Cheng Dai and colleagues treated the genus ''Pachykytospora'' as a synonym of ''Haploporus'' in 2002, and then in subsequent publications. Marcin Piątek proposed dividing ''Haploporus'' into two sections: sect. ''Haploporus'' (cap-like fruit bodies), and sect. ''Pachykytospora'' ( crust-like fruit bodies). Leif Ryvarden, who adopts a "pragmatic and conservative generic concept" in his 2014 work on European polypores, treats ''Haploporus'' as monotypic, containing only ''H. odorus''. Using ''Haploporus tuberculosis'' as a representative generic exemplar, molecular analysis showed ''Haploporus'' to be nested within the core polyporoid ...

Polyporaceae
The Polyporaceae are a family of poroid fungi belonging to the Basidiomycota. The flesh of their fruit bodies varies from soft (as in the case of the dryad's saddle illustrated) to very tough. Most members of this family have their hymenium (fertile layer) in vertical pores on the underside of the caps, but some of them have gills (e.g. ''Panus'') or gill-like structures (such as ''Daedaleopsis'', whose elongated pores form a corky labyrinth). Many species are brackets, but others have a definite stipe – for example, '' Polyporus badius''. Most of these fungi have white spore powder but members of the genus '' Abundisporus'' have colored spores and produce yellowish spore prints. Cystidia are absent. Taxonomy In his 1838 work ''Epicrisis Systematis Mycologici seu Synopsis Hymenomycetum'', Elias Magnus Fries introduced the "Polyporei". August Corda published the name validly the following year, retaining Fries's concept. American mycologist William Alphonso Murrill, ...

Haploporus Thindii
''Haploporus thindii'' is a species of poroid crust fungus in the family Polyporaceae. Found in China and India, it causes a white rot in woody substrates. Taxonomy The fungus was first described from south India in 1993 as ''Pachykytospora thindii''. In 2002, Yu-Cheng Dai and colleagues treated the genus ''Pachykytospora'' as a synonym of ''Haploporus'', and he subsequently transferred this fungus to '' Haploporus''. Description Fruit bodies of ''Haploporus thindii'' are crust-like, with a dimensions of up to long, wide, and 0.8 mm thick in the central part. The pore surface is coloured cream to pinkish-buff and has a corky texture. There is a distinct margin up to 5 mm wide that surrounds the crust. The angular pores number about three to four per millimetre. ''Haploporus thindii'' has a dimitic hyphal system (containing both generative and skeletal hyphae), and most of the generative hyphae feature clamp connections. The basidia are barrel shaped, with four s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Megasporoporia
''Megasporoporia'' is a genus of four species of crust fungi in the family Polyporaceae. The genus is characterized by its large spores (after which it is named), and dextrinoid skeletal hyphae. Taxonomy The genus was circumscribed by mycologists Leif Ryvarden and Jorge Eduardo Wright in 1982, with ''Poria setulosa'' as the type species. They included an additional three species: the new combinations ''M. cavernulosa'' and ''M. hexagonoides'', and the new species ''M. mexicana''. Six new species of ''Megasporoporia'' were introduced by Chinese mycologists between 2004 and 2009 as a result of taxonomic studies of wood-inhabiting fungi in China. Molecular analysis showed that ''Megasporoporia'' nested within the "core polyporoid clade", a grouping of polypore fungi roughly equivalent to a more narrowed but still broad concept of the family Polyporaceae. Later analysis that included the more recently described Chinese species revealed that the genus was not monophyl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Augustin Pyramus De Candolle
Augustin Pyramus (or Pyrame) de Candolle (, , ; 4 February 17789 September 1841) was a Swiss botanist. René Louiche Desfontaines launched de Candolle's botanical career by recommending him at a herbarium. Within a couple of years de Candolle had established a new genus, and he went on to document hundreds of plant families and create a new natural plant classification system. Although de Candolle's main focus was botany, he also contributed to related fields such as phytogeography, agronomy, paleontology, medical botany, and economic botany. De Candolle originated the idea of "Nature's war", which influenced Charles Darwin and the principle of natural selection. de Candolle recognized that multiple species may develop similar characteristics that did not appear in a common evolutionary ancestor; a phenomenon now known as convergent evolution. During his work with plants, de Candolle noticed that plant leaf movements follow a near-24-hour cycle in constant light, suggestin ...

Ellipsoid
An ellipsoid is a surface that may be obtained from a sphere by deforming it by means of directional scalings, or more generally, of an affine transformation. An ellipsoid is a quadric surface; that is, a surface that may be defined as the zero set of a polynomial of degree two in three variables. Among quadric surfaces, an ellipsoid is characterized by either of the two following properties. Every planar cross section is either an ellipse, or is empty, or is reduced to a single point (this explains the name, meaning "ellipse-like"). It is bounded, which means that it may be enclosed in a sufficiently large sphere. An ellipsoid has three pairwise perpendicular axes of symmetry which intersect at a center of symmetry, called the center of the ellipsoid. The line segments that are delimited on the axes of symmetry by the ellipsoid are called the ''principal axes'', or simply axes of the ellipsoid. If the three axes have different lengths, the figure is a triaxial ellipsoid (r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
