Hydnophlebia Omnivora
''Hydnophlebia omnivora'' is a species of crust fungus in the family Meruliaceae. It causes white rot in various woody angiosperms, being found in arid regions of the Southern United States, northern Mexico, and Uruguay. Taxonomy The fungus was first described scientifically in 1925 by American mycologist Cornelius Lott Shear as a species of '' Hydnum''. Kurt Hjortstam and Leif Ryvarden transferred it to the genus ''Hydnophlebia'' in 2009.

Meruliaceae
The Meruliaceae are a family of fungi in the order Polyporales. According to a 2008 estimate, the family contains 47 genera and 420 species. , Index Fungorum accepts 645 species in the family. Taxonomy The family was formally circumscribed by English mycologist Carleton Rea in 1922, with ''Merulius'' as the type genus. He also included the genera ''Phlebia'', '' Coniophora'' (now placed in the Coniophoraceae), and ''Coniophorella'' (now considered a synonym of ''Coniophora''). His description of the Meruliaceae was as follows: "Hymenium spread over veins, anastomosing pores, or quite smooth; ''edge of veins or pores fertile.''" Several genera formerly classified in the Meruliaceae were moved to the family Steccherinaceae based on molecular evidence. Description Meruliaceae species are crust-like or polyporoid, and often have a waxy appearance when dry. Their hyphal systems are monomitic (containing only tightly arranged generative hyphae), and these hyphae have clamp connec ...

Erast Parmasto
Erast Parmasto (28 October 1928 – 24 April 2012) was a noted Estonian mycologist, bioscientist and botanist and onetime director of the Estonian Institute of Zoology and Botany. Parmasto was born in Nõmme. He became a member of the Estonian Institute of Zoology and Botany in 1950 and served as its director from 1985 to 1990. His establishment of a mushroom herbarium in 1950 has since seen recognition of 160,000 samples, 37,000 of which Parmasto himself collected. Parmasto published more than 150 papers and 200 articles during his academic career and his works are commonly used in popular scientific and academic journals in Estonia. His expertise in the field of mycology has resulted in him being nicknamed "Seenevana", or the "grand old man of mushrooms". As a mycologist, the field with which Parmasto was most associated, he was best known for his establishment and enhancement of databases for species of mushrooms within Estonia. He was also the author of the first Estonia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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] |
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 ...

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.
