Sistotrema Resinicystidium
''Sistotrema'' is a genus of fungi in the family Hydnaceae. The genus contains at least 55 species and has a worldwide distribution. The type species is ''Sistotrema confluens'' Pers. (1794). Ecology The genus includes both terricolous and lignicolous species. Most species of ''Sistotrema'' are white rotting saprotrophs which often occur on highly decayed wood and on bark of attached, dead branches, but endophytic and ectomycorrhizal nutritional modes also exist in some species. ''Sistotrema confluens'' is ectomycorrhizal and ''S. alboluteum'', ''S. muscicola'' and ''S. albopallescens'' are suspected of being so. In the genus only ''S. confluens'' and ''S. subconfluens'' are known to grow on soil. Basidiocarps of ''Sistotrema'' generally start spore production very early. Morphology Only the type species ''S. confluens'', and ''S. subconfluens'', form stipitate basidiocarps while all other species in the genus form resupinate, corticioid basidiocarps. There is large ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Elias Magnus Fries
Elias Magnus Fries (15 August 1794 – 8 February 1878) was a Swedish mycologist and botanist. 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 obtained a doctorate in 1814. In the same year he was appointed an associate professorship in botany. He was elected a member of the Royal Swedish Academy of Sciences, and in 1824, became a full professor. In 1834 he became Borgström professor (Swed. ''Borgströmianska professuren'', a chair endowed by Erik Eriksson Borgström, 1708–1770) in applied economics at Uppsala University. The position was changed to "professor of botany and applied economics" in 1851. He was elected a Foreign Honorary Member of the American Academy of Arts and Sciences in 1849. That year he was also appointed director of the Uppsala University Botanica ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Parenthesome
Within the cells of some members of basidiomycetes fungi are found microscopic structures called parenthesomes or septal pore caps. They are shaped like parentheses and found on either side of pores in the dolipore septum which separates cells within a 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 .... Their function has not been established, and their composition has not been fully elucidated. The variations in their appearance are useful in distinguishing individual species. Generally, they are barrel shaped, with an endoplasmic reticulum covering. See also * Pit connection References * * Organelles Mycology Fungal morphology and anatomy {{Basidiomycota-stub ...

Botryobasidium
''Botryobasidium'' is a genus of corticioid fungi belonging to the order Cantharellales. Basidiocarps (fruit bodies) are ephemeral and typically form thin, web-like, white to cream, effused patches on the underside of fallen branches, logs, and leaf litter. Several species form anamorphs producing chlamydospores. All species are wood- or litter-rotting saprotrophs and the genus has a worldwide distribution. Taxonomy The genus was first described by Dutch mycologist M.A. Donk in 1931. Species had previously been referred to the genus '' Corticium'', formerly used for most corticioid fungi with effused fruit bodies. Donk recognized a group of species within ''Corticium'' that (microscopically) produced basidia in " botryose" clusters (hence ''Botryobasidium''), had wide, often right-angled hyphae, large two- to eight-spored basidia, and smooth basidiospores. He described a second genus, ''Botryohypochnus'', for species with ornamented basidiospores. The genus was later monograp ...

Agaricomycetes
The Agaricomycetes are a class of fungi in the division Basidiomycota. The taxon is roughly identical to that defined for the Homobasidiomycetes (alternatively called holobasidiomycetes) by Hibbett & Thorn, with the inclusion of Auriculariales and Sebacinales. It includes not only mushroom-forming fungi, but also most species placed in the deprecated taxa Gasteromycetes and Homobasidiomycetes. Within the subdivision Agaricomycotina, which already excludes the smut and rust fungi, the Agaricomycetes can be further defined by the exclusion of the classes Tremellomycetes and Dacrymycetes, which are generally considered to be jelly fungi. However, a few former "jelly fungi", such as ''Auricularia'', are classified in the Agaricomycetes. According to a 2008 estimate, Agaricomycetes include 17 orders, 100 families, 1147 genera, and about 21000 species. Modern molecular phylogenetic analyses have been since used to help define several new orders in the Agaricomycetes: Amylocorticiales ...

Cantharellales
The Cantharellales are an order of fungi in the class Agaricomycetes. The order includes not only the chanterelles (Cantharellaceae), but also some of the tooth fungi (Hydnaceae), clavarioid fungi ( Aphelariaceae and Clavulinaceae), and corticioid fungi ( Botryobasidiaceae). Species within the order are variously ectomycorrhizal, saprotrophic, associated with orchids, or facultative plant pathogens. Those of economic importance include edible and commercially collected ''Cantharellus'', ''Craterellus'', and ''Hydnum'' species as well as crop pathogens in the genera '' Ceratobasidium'' and '' Thanatephorus'' (''Rhizoctonia''). Taxonomy The order was originally proposed in 1926 by German mycologist Ernst Albert Gäumann to accommodate species within the phylum Basidiomycota having "stichic" basidia (basidia with nuclear spindles arranged longitudinally). On this basis, he included three families within the Cantharellales: the Cantharellaceae (including the Hydnaceae), the Clavul ...

Spindle Apparatus
In cell biology, the spindle apparatus refers to the cytoskeletal structure of eukaryotic cells that forms during cell division to separate sister chromatids between daughter cells. It is referred to as the mitotic spindle during mitosis, a process that produces genetically identical daughter cells, or the meiotic spindle during meiosis, a process that produces gametes with half the number of chromosomes of the parent cell. Besides chromosomes, the spindle apparatus is composed of hundreds of proteins. Microtubules comprise the most abundant components of the machinery. Spindle structure Attachment of microtubules to chromosomes is mediated by kinetochores, which actively monitor spindle formation and prevent premature anaphase onset. Microtubule polymerization and depolymerization dynamic drive chromosome congression. Depolymerization of microtubules generates tension at kinetochores; bipolar attachment of sister kinetochores to microtubules emanating from opposite cell pol ...

''Membranomyces'' is a genus of fungi in the family Clavulinaceae The Clavulinaceae are a family of fungi in the order Cantharellales. The family is not well defined, but currently comprises species of clavarioid (club and coral) fungi as well as some corticioid (crust- and patch-forming) fungi. These spec ....
