Pachykytospora Alabamae
''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 ...

Fungi
A fungus ( : fungi or funguses) is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and molds, as well as the more familiar mushrooms. These organisms are classified as a 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 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 group of related organisms, named the ''Eumycota'' (''t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Resupination
Resupination is derived from the Latin word ''resupinus'', meaning "bent back with the face upward" or "on the back". "Resupination" is the noun form of the adjective "resupine" which means "being upside-down, supine or facing upward". The word "resupinate" is generally only used in a botanical context – in everyday language, "supine" has a similar meaning. In botany, resupination refers to the "twisting" of flowers or leaves through about 180° as they open. Resupinate leaves have the petiole or "stalk" twisted - resupinate flowers twist as they open. Botanical examples Alstroemeriaceae Plants in the genus ''Alstroemeria'' have more or less resupinate leaves. Orchidaceae The flower of a typical plant in the orchid family Orchidaceae has three sepals and three petals. One petal, called the labellum, "lip" or "tongue", is typically quite different from the other two. It usually functions to attract an insect pollinator. As an orchid flower bud develops, the attachment o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

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.

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 the National Museum in Prague in 1957. From 1962 to 1990 he was a scientific employee of the Academy of Sciences of the Czech Republic at Průhonice. Kotlaba was for a long time in the editorial staff of the journal ''Mykologické listy'' and was the author of several books, some of a popular scientific nature. Honours '' Kotlabaea'' which is a genus of fungi in the family Pyronemataceae was published by Mirko Svrček in 1969, was named in his honour. The mycological journal ''Česká Mykologie'', to which he made numerous contributions, dedicated an edition to him on the occasion of his eightieth birthday in 2007.

Hypha
A hypha (; ) is a long, branching, filamentous structure of a fungus, oomycete, or actinobacterium. In most fungi, hyphae are the main mode of vegetative growth, and are collectively called a mycelium. Structure A hypha consists of one or more cells surrounded by a tubular cell wall. In most fungi, hyphae are divided into cells by internal cross-walls called "septa" (singular septum). Septa are usually perforated by pores large enough for ribosomes, mitochondria, and sometimes nuclei to flow between cells. The major structural polymer in fungal cell walls is typically chitin, in contrast to plants and oomycetes that have cellulosic cell walls. Some fungi have aseptate hyphae, meaning their hyphae are not partitioned by septa. Hyphae have an average diameter of 4–6 µm. Growth Hyphae grow at their tips. During tip growth, cell walls are extended by the external assembly and polymerization of cell wall components, and the internal production of new cell membrane. The S ...
