Sparassidaceae
The Sparassidaceae are a family of fungi in the order Polyporales. The family was circumscribed by German botanist Wilhelm Herter in 1910 to contain the genus '' Sparassis''. '' Sparassiella'' was added to the family in 1964. , ''Index Fungorum'' accepts 10 species in the Sparassidaceae. Description The fruit bodies of Sparassidaceae fungi consist of branched, fan-shaped segments that originate from a central core. The hyphal system is monomitic, with gloeoplerous hyphae (containing oil droplets). These hyphae have scattered clamp connections. The spores are smooth, thin- to somewhat thick-walled, and hyaline (translucent). Cystidia A cystidium (plural cystidia) is a relatively large cell found on the sporocarp of a basidiomycete (for example, on the surface of a mushroom gill), often between clusters of basidia. Since cystidia have highly varied and distinct shapes that ar ... are mostly absent from the hymenium. Sparassidaceae fungi cause brown rot. References Po ...

Polyporales Families
The Polyporales are an order of about 1800 species of fungi in the division Basidiomycota. The order includes some (but not all) polypores as well as many corticioid fungi and a few agarics (mainly in the genus ''Lentinus''). Many species within the order are saprotrophic, most of them wood-rotters. Some genera, such as ''Ganoderma'' and ''Fomes'', contain species that attack living tissues and then continue to degrade the wood of their dead hosts. Those of economic importance include several important pathogens of trees and a few species that cause damage by rotting structural timber. Some of the Polyporales are commercially cultivated and marketed for use as food items or in traditional Chinese medicine. Taxonomy History The order was originally proposed in 1926 by Swiss mycologist Ernst Albert Gäumann to accommodate species within the phylum Basidiomycota producing basidiocarps (fruit bodies) showing a gymnocapous mode of development (forming the spore-bearing surface ...

Sparassis
''Sparassis'' (also known as cauliflower mushroom) is a genus of parasitic and saprobic mushroom characterised by its unique shape and appearance and is found around the globe. Its appearance can be described as similar to a sea sponge, a brain or a head of cauliflower, hence its popular name. It is increasingly cultivated and sold in Korea, Japan, the United States and Australia. The generic name comes from the Greek ''sparassein'', meaning ''to tear''. Species The following species are recognised in the genus ''Sparassis'': *'' Sparassis americana'' R.H. Petersen *'' Sparassis brevipes'' Krombh. *'' Sparassis crispa'' ( Wulfen) Fr. *'' Sparassis cystidiosa'' Desjardin & Zheng Wang *'' Sparassis foliacea'' St.-Amans *'' Sparassis herbstii'' Peck *'' Sparassis kazachstanica'' Shvartsman *'' Sparassis laminosa'' Fries *'' Sparassis latifolia'' Y.C.

Sparassis Crispa
''Sparassis crispa'' is a species of fungus in the family Sparassidaceae. It is sometimes called cauliflower fungus. Description ''S. crispa'' grows in an entangled globe that is up to in diameter. The lobes, which carry the spore-bearing surface, are flat and wavy, resembling lasagna noodles, coloured white to creamy yellow. When young they are tough and rubbery but later they become soft (they are monomitic). The odour is pleasant and the taste of the flesh mild. The spore print is cream, the smooth oval spores measuring about 5–7 µm by 3.5–5 µm. The flesh contains clamp connections. Ecology, distribution and related species This species is a brown rot fungus, found growing at the base of conifer trunks, often pines, but also spruce, cedar, larch and others. It is fairly common in Great Britain and temperate Europe (but not in the boreal zone). In Europe there is also a less well-known species of the same genus, ''Sparassis brevipes'', which can be disti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wilhelm Gustav Franz Herter
Wilhelm (Guillermo) Gustav Franz Herter (10 January 1884 in Berlin – 17 April 1958 in Hamburg) was a German botanist and mycologist. In 1908 he received his doctorate in Berlin with a dissertation on the genus ''Lycopodium''. From 1923 to 1939 he lived and worked in Uruguay, gaining Uruguayan citizenship in 1925. In Montevideo, he was associated with its botanical garden and museum, and in the meantime taught classes at the university. In 1934 he became director of the ''Revista Sudamericana de Botánica''.JSTOR Global Plants biography During the Second World War, Herter was the director of the nazi-german publishing series 'Veröffentlichungen der Staatlichen Botanischen Anstalten des Generalgouvernements".

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 ...

Wood-decay Fungus
A wood-decay or xylophagous fungus is any species of fungus that digests moist wood, causing it to rot. Some species of wood-decay fungi attack dead wood, such as brown rot, and some, such as ''Armillaria'' (honey fungus), are parasitic and colonize living trees. Excessive moisture above the fibre saturation point in wood is required for fungal colonization and proliferation. In nature, this process causes the breakdown of complex molecules and leads to the return of nutrients to the soil. Wood-decay fungi consume wood in various ways; for example, some attack the carbohydrates in wood and some others decay lignin. The rate of decay of wooden materials in various climates can be estimated by empirical models.Viitanen, T. et al. (2010). Towards modelling of decay risk of wooden materials. European Journal of Wood and Wood Products 68:303-313. Wood-decay fungi can be classified according to the type of decay that they cause. The best-known types are brown rot, soft rot, and whit ...

Hymenium
The hymenium is the tissue layer on the hymenophore of a fungal fruiting body where the cells develop into basidia or asci, which produce spores. In some species all of the cells of the hymenium develop into basidia or asci, while in others some cells develop into sterile cells called cystidia (basidiomycetes) or paraphyses (ascomycetes). Cystidia are often important for microscopic identification. The subhymenium consists of the supportive hyphae from which the cells of the hymenium grow, beneath which is the hymenophoral trama, the hyphae that make up the mass of the hymenophore. The position of the hymenium is traditionally the first characteristic used in the classification and identification of mushrooms. Below are some examples of the diverse types which exist among the macroscopic Basidiomycota and Ascomycota. * In agarics, the hymenium is on the vertical faces of the gills. * In boletes and polypores, it is in a spongy mass of downward-pointing tubes. * In puffballs, ...

Cystidia
A cystidium (plural cystidia) is a relatively large cell found on the sporocarp of a basidiomycete (for example, on the surface of a mushroom gill), often between clusters of basidia. Since cystidia have highly varied and distinct shapes that are often unique to a particular species or genus, they are a useful micromorphological characteristic in the identification of basidiomycetes. In general, the adaptive significance of cystidia is not well understood. Classification of cystidia By position Cystidia may occur on the edge of a lamella (or analogous hymenophoral structure) (cheilocystidia), on the face of a lamella (pleurocystidia), on the surface of the cap (dermatocystidia or pileocystidia), on the margin of the cap (circumcystidia) or on the stipe (caulocystidia). Especially the pleurocystidia and cheilocystidia are important for identification within many genera. Sometimes the cheilocystidia give the gill edge a distinct colour which is visible to the naked eye or wit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hyaline
A hyaline substance is one with a glassy appearance. The word is derived from el, ὑάλινος, translit=hyálinos, lit=transparent, and el, ὕαλος, translit=hýalos, lit=crystal, glass, label=none. Histopathology Hyaline cartilage is named after its glassy appearance on fresh gross pathology. On light microscopy of H&E stained slides, the extracellular matrix of hyaline cartilage looks homogeneously pink, and the term "hyaline" is used to describe similarly homogeneously pink material besides the cartilage. Hyaline material is usually acellular and proteinaceous. For example, arterial hyaline is seen in aging, high blood pressure, diabetes mellitus and in association with some drugs (e.g. calcineurin inhibitors). It is bright pink with PAS staining. Ichthyology and entomology In ichthyology and entomology, ''hyaline'' denotes a colorless, transparent substance, such as unpigmented fins of fishes or clear insect wings. Resh, Vincent H. and R. T.

Basidiospore
A basidiospore is a reproductive spore produced by Basidiomycete fungi, a grouping that includes mushrooms, shelf fungi, rusts, and smuts. Basidiospores typically each contain one haploid nucleus that is the product of meiosis, and they are produced by specialized fungal cells called basidia. Typically, four basidiospores develop on appendages from each basidium, of which two are of one strain and the other two of its opposite strain. In gills under a cap of one common species, there exist millions of basidia. Some gilled mushrooms in the order Agaricales have the ability to release billions of spores. The puffball fungus ''Calvatia gigantea'' has been calculated to produce about five trillion basidiospores. Most basidiospores are forcibly discharged, and are thus considered ballistospores. These spores serve as the main air dispersal units for the fungi. The spores are released during periods of high humidity and generally have a night-time or pre-dawn peak concentration in the ...
