Lepteutypa Cupressi
''Lepteutypa cupressi'' is a plant pathogen which causes a disease ("Cypress canker") in ''Cupressus'', ''Thuja'', and related conifer types. 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. Dual naming of fungi Fungi are classified primarily based on the structures associated with sexual reproduction, which tend to be evolutionarily conserved. However, many fungi reproduce only asexually, and cannot easily be classified based on sexual characteristics; some produce both asexual and sexual states. These problematic species are often members of the Ascomycota, but a few of them belong to the Basidiomycota. Even among fungi that reproduce both sexually and asexually, often only one method of reproduction can be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monochaetia
''Monochaetia'' is a genus of fungi in the family Sporocadaceae. Species in the genus are typically plant parasites and saprobes, and cause leaf spot diseases on various hosts. The genus ''Monochaetia'' was introduced by Allescher in 1902, it had 23 species originally. Allescher (1902) also designated the type as ''Monochaetia monochaeta'', which has a single apical appendage (Guba 1961; Maharachch. et al. 2014; Senanayake et al. 2015). Steyaert (in 1949) transferred numerous ''Monochaetia'' species to ''Pestalotiopsis'' or '' Truncatella''. More than 40 species of ''Monochaetia'' were recognised by the monograph of Guba (1961). There are 127 ''Monochaetia'' epithets in the Index Fungorum (as of 31 March 2022) and most have been transferred to other genera such as ''Sarcostroma'', ''Seimatosporium'' and ''Seiridium ''Lepteutypa'' is a genus of plant pathogens in the family Amphisphaeriaceae.

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. 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 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 scale bearing 1–2 small se ...

Cupressus
''Cupressus'' is one of several genera of evergreen conifers within the family Cupressaceae that have the common name cypress; for the others, see cypress. It is considered a 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 ''cipres'' from the Latin ''cyparissus'', which is the latinisation of the Greek κυπάρισσος (''kypárissos''). Taxonomy There has long been significant uncertainty about the New World members of ''Cupressus'', with several studies recovering them as forming a distinct clade from the Old World members. A 2021 molecular study found ''Cupressus'' to be the sister genus to ''Juniperus'', whereas the western members (classified in '' Callitropsis'' and ''Hesperocyparis'') were found to be sister to ''Xanthocyparis''. Description They are evergreen trees or large shrubs, growing to 5–40 m tall. The leaves are scale-lik ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 pat ...

Plant Pathogen
Plant pathology (also phytopathology) is the scientific study of 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, vertebrate, or other pests that affect plant health by eating plant tissues. Plant pathology also involves the study of pathogen identification, disease etiology, disease cycles, economic impact, plant disease epidemiology, plant disease resistance, how plant diseases affect humans and animals, pathosystem genetics, and management of plant diseases. Overview Control of plant diseases is crucial to the reliable production of food, and it provides significant problems in agricultural use of land, water, fuel and other inputs. Plants in both natural and cultivated populat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seiridium
''Lepteutypa'' is a genus of plant pathogens in the family Amphisphaeriaceae. First described by the Austrian mycologist Franz Petrak in 1923, the genus contains 10 species according to a 2008 estimate. 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'' can 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'' should be preferred for the species as a whole. On the other hand, no sexual stage of species ''Seiridium cardinale'' is known, so that is its only name. ''Seiridium cardinale'' and ''L. cupressi'' are important to gardeners and foresters as they cause the devastating Cyprus canker disease of ''Cupressus'', ''Thuja ''Thuja'' ( ) is a genus of coniferous tree or shrub in the Cupressaceae (cypress family). ...
