Endoconidiophora Coerulescens
''Ceratocystis coerulescens'' is an ascomycete fungus and the causal agent of sapstreak disease in sugar maple trees. There is debate about whether it is one species or two; the second being ''Ceratocystis virescens.'' For simplicity, this page will refer to this pathogen as one species. It is also known by its anamorph name ''Endoconidiophora virescens.'' Host and symptoms This fungus is often found as a saprophyte on logs of woody species. It causes sapstreak disease in just one host species: ''Acer saccharum'', commonly known as the sugar maple or rock maple. Symptoms include a sparse crown, dieback, dwarfed leaves, and cankers. Infected trees may die suddenly or languish for 2–4 years. The symptom most characteristic of sapstreak disease is yellowish-green stained wood that is also very moist. Once the wood is cut and dries, the stains turn light brown, so they're difficult to see and diagnose at that point. Disease cycle As an ascomycete, ''Ceratocystis coerulescens'' pro ...

Acer Saccharum
''Acer saccharum'', the sugar maple, is a species of flowering plant in the soapberry and lychee family Sapindaceae. It is native to the hardwood forests of eastern Canada and the eastern United States. Sugar maple is best known for being the primary source of maple syrup and for its brightly colored fall foliage. It may also be called "rock maple," "sugar tree," "sweet maple," or, particularly in reference to the wood, "hard maple," "Bird's eye figure, birds-eye maple," or "curly maple," the last two being specially Figure (wood), figured lumber. Description ''Acer saccharum'' is a deciduous tree normally reaching heights of , and exceptionally up to . A 10-year-old tree is typically about tall. As with most trees, forest-grown sugar maples form a much taller trunk and narrower canopy than open-growth ones. The leaf, leaves are deciduous, up to long and wide, palmate, with five lobes and borne in opposite pairs. The basal lobes are relatively small, while the upper lobes a ...

Ascocarp
An ascocarp, or ascoma (: ascomata), is the fruiting body ( sporocarp) of an ascomycete phylum fungus. It consists of very tightly interwoven hyphae and millions of embedded asci, each of which typically contains four to eight ascospores. Ascocarps are most commonly bowl-shaped (apothecia) but may take on a spherical or flask-like form that has a pore opening to release spores (perithecia) or no opening (cleistothecia). Classification The ascocarp is classified according to its placement (in ways not fundamental to the basic taxonomy). It is called ''epigeous'' if it grows above ground, as with the morels, while underground ascocarps, such as truffles, are termed ''hypogeous''. The structure enclosing the hymenium is divided into the types described below (apothecium, cleistothecium, etc.) and this character ''is'' important for the taxonomic classification of the fungus. Apothecia can be relatively large and fleshy, whereas the others are microscopic—about the size of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Stained Wound
A stain is a discoloration that can be clearly distinguished from the surface, material, or medium it is found upon. They are caused by the chemical or physical interaction of two dissimilar materials. Accidental staining may make materials appear used, degraded or permanently unclean. Intentional staining is used in biochemical research, and for artistic effect, such as in wood staining, rust staining and stained glass. Types There can be intentional stains (such as wood stains or paint), indicative stains (such as food coloring dye, and staining, the use of one or more substances to enhance visibility of samples in a microscope or other imaging device. Numerous naturally-occurring stains exist, such as rust on iron and a patina on bronze, as do accidental stains such as from ketchup and oil on fabrics and other materials. Different types of material can be stained by different substances, and stain resistance is an important characteristic in modern textile engineering. ...

Armillaria
''Armillaria'' is a genus of fungi that includes the '' A. mellea'' species ('honey fungus') that live on trees and woody shrubs. It includes about 10 species formerly categorized summarily as ''A. mellea''. ''Armillaria'' sp. are long-lived and form the largest living fungi in the world. The largest known specimen (an ''A. ostoyae'') covers more than in Oregon and is estimated to be 2,500 years old. Some species of ''Armillaria'' display bioluminescence. ''Armillaria'' can be a destructive forest pathogen. It causes "white rot" root disease. As it feeds on dead plant material, it can kill its host with little negative effect to itself. Taxonomy The name ''Armillaria'' was defined in 1821 by Elias Magnus Fries, but at that time most gilled mushrooms were considered to belong to genus ''Agaricus'' and ''Armillaria'' was only a subgenus (a "tribe"). In 1857, Friedrich Staude established the independent genus. ''Armillaria'' species morphologically similar t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Xylaria
''Xylaria'' is a genus of ascomycetous fungi commonly found growing on dead wood. The name comes from the Greek ''xýlon'' meaning ''wood'' (see xylem). 'Outline of Fungi and fungus-like taxa' by Wijayawardene et al. lists up to (ca. 571) species (in 2020), and around 454 records are listed by Species Fungorum (including synonyms). Two of the common species of the genus are '' Xylaria hypoxylon'' and '' Xylaria polymorpha''. '' Xylaria hypoxylon'', known by the common names stag's horn and candle-snuff fungus, is the most conspicuous because of its erect, 3–7 cm tall, antler-like ascocarps (fruitbodies) which are black at the base (where the perithecia are embedded) but white and branched towards the top, where the fruiting bodies produce white conidia A conidium ( ; : conidia), sometimes termed an asexual chlamydospore or chlamydoconidium (: chlamydoconidia), is an asexual, non- motile spore of a fungus.

Fungal Plant Pathogens And Diseases
A fungus (: fungi , , , or ; 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 one of the traditional eukaryotic kingdoms, along with Animalia, Plantae, and either Protista or 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'' (''true fungi'' or ' ...

Microascales
The Microascales are an order of fungi in the class Sordariomycetes, subclass Hypocreomycetidae. This is a relatively small order of mostly saprobic fungi that live in soil, rotting vegetation and dung. Some species are plant pathogens, such as '' Ceratocystis fimbriata'', transmitted by beetles to living trees and causing cacao wilt and many other economically important diseases. Species in the genus '' Pseudallescheria'' (family Microascaceae) are pathogenic to humans The order was circumscribed in 1980. Wijayawardene et al. in 2020 added more families and genera to the order. Description The Microascales are characterized by a lack of stroma, black perithecial ascomata with long necks or rarely with cleistothecial ascomata that lack paraphyses. They have roughly spherical and short-lived asci that develop singly or in chains. Nonseptate, colorless ascospore In fungi, an ascospore is the sexual spore formed inside an ascus—the sac-like cell that defines the division ...
