  Ascocarp. Who is Ascocarp? What is Ascocarp? Where is Ascocarp? Definition of Ascocarp. Meaning of Ascocarp.
An ascocarp is the fruiting body of some ascomycete fungi, containing millions of asci, each of which contains typically eight ascospores.
Ascocarps are most commonly bowl-shaped, but may take on a number of other designs.
There are three described types of ascocarps based upon shape: cleistothecium (spherical), apothecium (cup-shaped), and perithecium (slightly open at one end, like a flask or jug).

 Palaeos Fungi: Glossary A
Ascocarp : the fruiting body of an ascomycete; the multicellular structure that produces asci, and acts as the platform from which the spores are launched.
The ascocarps produced by ascohymenial development extend out into the medium, as in the image at apothecium, and the asci are unitunicate.
Ascolocular : relating to a mode of ascocarp growth in which a perithecium develops within a cushioning hollow of cells (the stroma) which is nested in a depression of the hymenium (a locule).

 Abstract 4882 from Intl. Bot. Congress 1999
Ascocarps of Microsphaera pulchra constitute the main mechanism for winter survival and source of primary inoculum for powdery mildew in Cornus florida.
Ascocarp formation occurs late in the season and may be influenced by host physiology and /or environmental factors.
Since time is a factor in the maturation of ascocarps to a level that can survive winter, the timing of ascocarp formation and development have significant implications on primary inoculum density.

 Ascus - Wikipedia, the free encyclopedia
An ascus (plural asci) is the spore-bearing container produced in the ascocarps of ascomycete fungi.
When one ascus bursts, it triggers the bursting of all the other asci in the ascocarp.
Asci are used in laboratories for studying the process of meiosis, because the four cells produced by meiosis line up in regular order.

Two types of Morchella variation were studied—spore strain variation manifested through an anomaly on petri plates, and differences in ascocarp (fruiting body) tissue thickness as a method of coping with weather.
This means that the dramatic differences in appearance were the result of the ascocarp producing spores which were intrinsically different.
Thin tissued morel ascocarps are needed in years when there is much rain and humidity slowing the rate of dehydration.

 Anomaly in Morchella Research.
The anomaly was a disc of high density (felt-like) mycelium containing ascocarp pigment and having a rubbery, brittle tissue, similar to that of the ascocarp, below it.
The cell structure of the high density mycelium was filamentous on the upper surface, with cell density increasing toward the agar.
Considering the structured nature of the growth, including zoned ascocarp pigment and a tissue, the high density mycelium appeared to be a rudimentary formation of a mushroom as it existed earlier in evolution.

This ascocarp type may be variously shaped, but is typically flasked-shaped or globose with a small ostiole through which the ascospores are released.
Asci are unitunicate and are arranged, in a single fertile layer throughout the base of the perithecium or in a fascicle.

Most species produce asci and ascospores in an ascocarp, which is a complex fruiting body made up of tightly interwoven mycelium, but some produce "naked" asci, i.e.
Characteristics that have been traditionally used to classify the Ascomycota, such as thallus type, ascocarp type and development and ascus types, now appear to be less useful as indicators of phylogeny.
In these species, asci and ascospores are still borne naked and are not produced in an ascocarp.

Ascocarps formed late in the growing season (September-November) when relatively low temperatures (< 27°C) persisted for at least 2 weeks, but ascocarp abundance was not influenced by disease severity.
Ascocarps formed within 12-14 days at 18°C/ 10°C (day/night) and 23°C/15°C, but required 25 days at 26°C/18°C; no ascocarps formed at 28°C/ 20°C. Because ascocarps are an important source of primary inoculum for dogwood powdery mildew, ascocarp survival was evaluated in a 2-year study (1998-2000).
Because ascocarps need time to mature, the timing of ascocarp initiation affects ascocarp maturity and thus winter survival and primary inoculum density.

The first exact knowledge as to the origin of the ascocarp was the work of Stahl on Collema in 1877.
He showed that the archicarp consisted of two parts, a lower coiled portion, the ascogonium, and an upper portion, the trichogyne, which projected from the thallus.
The Ascolichenes are again divided ihto Fyrenocarpeae or Pyrenolichenes and Gymnocarpeae or Discolic/ienes; the first having an ascocarp of the nature of aperithecium, the second bearing their ascospores in an open apothecium.

In biology an 'ascocarp-specific ascus' is not only a part of an ascocarp, it is also an example of a sporophore, a structure that contains spores.
