The name ''Seiridium cupressi'' (formerly '' Coryneum cupressi'') is for the anamorph In mycology, the terms teleomorph, anamorph, and holomorph apply to portions of the life cycles of fungi in the phyla Ascomycota and Basidiomycota: *Teleomorph: the sexual reproductive stage (morph), typically a fruiting body. *Anamorph: an ase ... of this fungus, that is, it is used for the asexual form. Now that it is known to have a sexual stage the genus name ''Lepteutypa'' should take precedence.

Teleomorph
In mycology, the terms teleomorph, anamorph, and holomorph apply to portions of the life cycles of fungi in the phyla Ascomycota and Basidiomycota: *Teleomorph: the sexual reproductive stage (morph), typically a fruiting body. *Anamorph: an asexual reproductive stage (morph), often mold-like. When a single fungus produces multiple morphologically distinct anamorphs, these are called synanamorphs. *Holomorph: the whole fungus, including anamorphs and teleomorph. The terms were introduced in 1981 to simplify the discussion of the procedures of the existing dual-naming system, which (1) permitted anamorphs to have their separate names but (2) treated teleomorphic names as having precedence for being used as the holomorphic name. The ''Melbourne Code'' removes the provisions and allows all names to compete on equal footing for priority as the correct name of a fungus, and hence does not use the term ''holomorph'' any more.

Cypress Canker
Cypress canker is a disease affecting ''Cupressus'' species, caused by one of several species of fungus in the genus ''Seiridium''. Infection causes die-back of twigs and branches in susceptible cypress trees, with rapidly increasing amounts of damage and the death of the tree. History The first epidemic of cypress canker was recorded in California in 1928, with Monterey cypress (''Cupressus macrocarpa'') being affected. Within a few years the local populations of this tree had been killed. The species is widely traded as an ornamental tree and the disease had soon spread worldwide, probably with nursery stock. Within five decades the disease had reached New Zealand, France, Chile, Italy, Argentina, Greece, most of Europe, Canada, North Africa, South Africa and Australia. The causal agent of this pandemic spread was the pathogenic fungus '' Seiridium cardinale'', with '' Seiridium cupressi'' and '' Seiridium unicorne'' sometimes being involved, but being less aggressive; other pa ...

Fungal Tree 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 motility, 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 ' ...

Xylariales
The Xylariales are an order (biology), order of fungi within the class (biology), class Sordariomycetes (also known as Pyrenomycetes), subdivision Pezizomycotina, division (mycology), division Ascomycota. It was the original order of the Class (taxonomy), subclass Xylariomycetidae. Xylariales was circumscription (taxonomy), circumscribed in 1932 by Swedish mycologist John Axel Nannfeldt, and Xylariomycetidae by Ove Erik Eriksson and Katarina Winka in 1997. Taxonomy Early classifications of the Xylariales varied considerably, with taxonomists recognising anywhere from three to eleven family (biology), families within the order. A milestone in understanding the order's composition came from Smith, Liew, and Hyde's 2003 molecular phylogenetics study, which established the Xylariales as a monophyletic group containing seven families: Amphisphaeriaceae, Apiosporaceae, Clypeosphaeriaceae, Diatrypaceae, Graphostromataceae, Hyponectriaceae, and Xylariaceae. During this period, fungi in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Thuja
''Thuja'' ( ) is a genus of coniferous tree or shrub in the Cupressaceae (cypress family). There are five species in the genus, two native to North America and three native to eastern Asia. The genus is monophyletic and sister to ''Thujopsis''. Members are commonly known as arborvitaes (from the Latin term for 'tree of life'), thujas or cedars. Description ''Thuja'' are evergreen trees growing from tall, with stringy-textured reddish-brown Bark (botany), bark. The shoots are flat, with side shoots only in a single plane. The leaves are scale-like and long, except young seedlings in their first year, which have needle-like leaves. The scale leaves are arranged in alternating decussate pairs in four rows along the twigs. The male cones are small, inconspicuous, and are located at the tips of the twigs. The female conifer cone, cones start out similarly inconspicuous, but grow to about long at maturity when 6–8 months old; they have 6-12 overlapping, thin, leathery scales, each ...

Cupressus
''Cupressus'' (common name cypress) is one of several genus, genera of evergreen conifers within the Family (biology), family Cupressaceae; for the others, see cypress. It is considered a Polyphyly, polyphyletic group. Based on genetic and morphological analysis, the genus ''Cupressus'' is found in the subfamily Cupressoideae. The common name "cypress" comes via the Old French from the Latin , which is the Latinisation (literature), latinisation of the Greek language, Greek κυπάρισσος (''kypárissos''). The name derives from Cyparissus, a mythological figure who was turned into a tree after killing a stag. As currently treated, these cypresses are native plants in scattered localities in mainly warm temperate climate regions in the Northern Hemisphere, including northwest Africa, the Middle East, the Himalayas, southern China and northern Vietnam. As with other pinophyta, conifers, extensive cultivation has led to a wide variety of forms, sizes and colours, that are gro ...

Plant Pathogen
Plant diseases are diseases in plants caused by pathogens (infectious organisms) and environmental conditions (physiological factors). Organisms that cause infectious disease include fungi, oomycetes, bacteria, viruses, viroids, virus-like organisms, phytoplasmas, protozoa, nematodes and parasitic plants. Not included are ectoparasites like insects, mites, vertebrates, or other pests that affect plant health by eating plant tissues and causing injury that may admit plant pathogens. The study of plant disease is called plant pathology. Plant pathogens Fungi Most phytopathogenic fungi are Ascomycetes or Basidiomycetes. They reproduce both sexually and asexually via the production of spores and other structures. Spores may be spread long distances by air or water, or they may be soil borne. Many soil inhabiting fungi are capable of living saprotrophically, carrying out the role of their life cycle in the soil. These are facultative saprotrophs. Fungal diseases ma ...

Creve Coeur Lake Memorial Park
Creve Coeur Lake Memorial Park (also called Creve Coeur County Park) is a St. Louis County park located in Maryland Heights, Missouri, United States. The park is the largest in the St. Louis County Parks system and includes Creve Coeur Lake, an oxbow lake which is one of the largest natural lakes in Missouri. Naming The name of the park, drawn from the French "''creve coeur''," is said to have originated from the shape of the lake. Folklore has it that it formed into the shape of a broken heart after an incident of unrequited love between a French fur trader and a local Native American woman. Brokenhearted, she cast herself into the lake, thus causing its reshaping, according to the tale. Description The park has facilities for picnicking, tennis courts, multi-purpose athletic fields, and an archery course. Creve Coeur Park includes Crystal Springs Quarry Golf Course, an 18-hole course opened in 2001. In December 2003, construction for the Creve Coeur Lake Memorial Park ...

Seiridium
''Seiridium'' is a genus of plant pathogens in the family Sporocadaceae. The genus '' Lepteutypa'' is teleomorphic (reproducing sexually) and the corresponding anamorphic name, used to describe the asexual form, is ''Seiridium'' (formerly ''Coryneum''). For instance, the name ''Seiridium cupressi'' is still be used for the anamorphic form of that species, but now that it is known that a sexual stage exists, the name ''Lepteutypa cupressi''. On the other hand, no sexual stage of species '' Seiridium cardinale'' is known, so that is its only name. '' Seiridium cardinale'' is important to gardeners and foresters as they cause the devastating Cypress canker disease on ''Cupressus'', ''Thuja'', and related conifers in Northern Europe, America, Australia, and New Zealand. ''Seiridium cardinale'' is from California and was introduced to Europe around the 1930s, probably from infected nursery stock. A separate introduction affected the southern hemisphere.
