  Teleomorph, anamorph and holomorph - Wikipedia, the free encyclopedia
Fungi are placed into particular taxa based on reproductive similarities.
This system is complicated and often confusing but can be a useful method for plant pathologists trying to identify a pathogen.
Fungi that do not produce a teleomorph stage (or in cases in which it has yet to be observed) are placed into the Deuteromycota.

While most teleomorph genera (those classified in the Eurotiales) have been associated with an anamorph species in the genera Aspergillus or Penicillium, there are many anamorph species in these genera which have never been associated with a teleomorph in the Eurotiales.
The teleomorph genera are distinguished by the ornamentation on the cleistothecium.
Teleomorph species are distinguished by the anamorph conidia and conidiophores, although it is possible to use only anamorph features to identify Teleomorph genera, it is always better to do this with the cleistothecia.

In ascomycetous and basidiomycetous fungi (including Ustilaginales) with mitotic asexual morphs (anamorphs) as well as a meiotic sexual morph (teleomorph), the correct name covering the holomorph (i.e., the species in all its morphs) is - except for lichen-forming fungi - the earliest legitimate name typified by an element representing the teleomorph, i.e.
For a binary name to qualify as a name of a holomorph, not only must its type specimen be teleomorphic, but also the protologue must include a description or diagnosis of this morph (or be so phrased that the possibility of reference to the teleomorph cannot be excluded).
The name Penicillium brefeldianum B. Dodge (1933), based on teleomorphic and anamorphic material, is a valid and legitimate name of a holomorph, in spite of the attribution of the species to a form-genus It is legitimately combined in a holomorphic genus as Eupenicillium brefeldianum (B. Dodge) Stolk & D. Scott (1967).

Fungi that do not produce a teleomorph stage (or in cases in which it has yet to be observed) are placed into the DeuteromycotaThe Deuteromycota are a form division, including those fungi in which sexual reproduction is unknown.
This is a junk-basket category for forms of uncertain affinity, and is not treated formally in further recent systems, although it is still used widely by plant pathologists (see plant pathology) for the purposes of quick diagnosis and when the teleomorph stage of the particular organism is unknown.

The terms anamorph and teleomorph are merely descriptive nomencla­tural and not karyological terms (Weresub and Hennebert, 1979; Korf and Hennebert, 1993) although the terms mitospo­ric and meiosporic have been advocated to substitute them (Reynolds and Taylor, 1993) and supported by Hawksworth and Mouchacca (1994) and Hawksworth et al.
A "teleomorph name" is a name typified by a teleomorph (in brief: "teleo-typified") and assigned holo­morphic application under Art.
The nomenclatures of teleomorphic and anamorphic fungi continue to coexist but are interspersed in a unified classification with one name for each fungus in either teleomorph- or anamorph-generic combinations.

The teleomorph name of the species is to be used for the formal designation of the teleo-connected type or other such species of a correlated anamorph-generic name.
Names of anamorph genera, the type species of which is connected to a teleomorph, are not to be repressed but are superseded because of their restricted anamorphic application and available to accommodate unconnected species even when their name is an anamorphic synonym of a teleo-typified generic name.
The teleomorph name of the species is to be used for the formal designation of the teleo-connected type or other species of a correlated anamorph generic name.

Principally because the properties of a food spoilage fungus are strongly influenced by the presence of a teleomorph.
No one uses }{\i\fs24\lang3081 Penicillium dodgei}{\fs24\lang3081 for }{\i\fs24\lang3081 Eupenicillium brefeldianum}{\fs24\lang3081 because we insist that the teleomorph name is the correct one to use, as the anamorph is not encountered alone in culture.
As long as this is not achieved, the complete synonymy of a certain teleomorph- with a corresponding anamorph- genus cannot be declared.\rdblquote I appreciate (Gary Samuels, 06/04/00), that some anamorph genera are not well defined, and that for some fungi, wooly names would be a help.

Principle: All epithets, whether based on a teleomorphic or an anamorphic type published before or after D, are to be considered as of holomorphic application, retroac­tively back to the starting-point of the taxonomic group concerned.
When naming a teleomorphic holomorph, its correct generic name must be that of a teleomorphic genus.
The only correct binomial of teleo­morphic holomorphs is therefore the combined ana- or teleo-typified epithet with a teleo-typified generic name.

 Mycology Online -- Scedosporium
The taxonomy of both the teleomorph (sexual or perfect state) and anamorph (asexual or conidial state) phase of this fungus is complicated by several recent name changes.
Briefly, the correct name for the teleomorph phase is Pseudallescheria boydii (the names Petriellidium boydii and Allescheria boydii are no longer valid).
Finally, because all species of Pseudallescheria have Scedosporium anamorphs, it is presumptive to use the teleomorph name to describe this fungus without seeing cleistothecia (ascocarps).

There seeems to be an intricate, close and complex relationship between the Termitomyces anamorph and the teleomorph which ensures the timed dispersal of mycelogenic propagules, the survival of the termite-dependent mycobiont and continuity of the eons-old entomo-mycomutualistic relationship.
The teleomorph is the light-dependent epigeal basidiospore producing fruitbody stage.
Using simple fungal media and healthy tissue from the teleomorph it is relatively easier to obtain either sporodochial anamorphic cultures with farinaceous/cerebroid textures or purely vegetatative non-differentiating cultures.

Asexual structures are referred to as the anamorph while the sexual structure is referred to as the teleomorph.
In cases where both the teleomorph and anamorph structures of a fungus are known, teleomorph is generally used.
However, if the teleomorph is known but rarely encountered or rarely observed, then it is acceptable to use the name of the anamorph.

Retain primacy of the teleomorph but permit description of species for which no telemorph is known as botanical species; permit inclusion of genera for which no teleomorph is known as botanical genera.

 Mating type distribution and incidence of the teleomorph of Ascochyta rabiei (Didymella rabiei) in Canada   (Site not responding. Last check: 2007-11-03)
Wind-borne ascospores produced by the teleomorph play an important role in disease spread and pathogen survival in many regions.
The teleomorph was detected on the residue by microscopic dissection and by two methods of ascospore discharge, one using a novel and inexpensive apparatus.
The occurrence of the teleomorph stage in the region may increase field-to-field spread of ascochyta blight of chickpea and contribute to increased genetic variability of the pathogen in western Canada.
