  Fruiting body - Wikipedia, the free encyclopedia
Fruiting bodies that are visible to the naked eye, especially fruiting bodies of a more or less agaricoid morphology, are often referred to as mushrooms.
If the spores are borne on the club-like cells called basidia, the fruiting body can be called a basidiocarp (or basidioma, plural: basidiomata); if they are in sac-like asci, the fruiting body is an ascocarp (or ascoma, plural: ascomata).
Multicellular spore-producing structures on fungus-like organisms, such as slime molds, and some colonial bacteria, such as the myxobacteria, are also called "fruiting bodies".

Ascoma Congo was initially established in the centre of Pointe Noire in 2004 and then in Brazzaville with the intention of carrying out insurance and reinsurance brokerage throughout the Republic of the Congo.
Ascoma Congo benefits from the support of the ASCOMA network, which has been active in Africa for over 50 years and represents the largest insurance and reinsurance brokerage groups in the world.
Ascoma Congo makes its experience and expertise available to the whole spectrum of economic players - from retailers to professionals, from small- and medium-sized businesses to major industrial companies.

The ascoma was said to be variably setose and producing either an ostiolar opening or radiate cracks for the release of the ascospores (Sydow and Sydow 1913; Hughes 1976).
Ascoma subglobose to ampulliform, ostiolate, 80–230 µm diameter; ascoma setae dark brown, septate or not, 48–200 µm in length; ascus fissitunicate; ascospores hyaline, 2–3 septate, fusiform-elliptical, 18–32 × 5–10 µm.
Ascoma sparsa vel conferta, sessilia vel infossa, semi-globosa, in sicco collabentia, brunnea, uniloculata, centrum jodo caerulescens.

The ascocarps produced by ascolocular growth do not grow into the medium, and the asci are usually bitunicate.
Ascoma: (pl. ascomata) (1) same as ascocarp (2) "an ascocarp having the spore-bearing layer of cells (the hymenium) on a broad disklike receptacle." This latter definition is frequently cited but appears to be either incorrect or useless.
The ascus stretches up into the narrow neck of the ascoma, and the ascospores are expelled.

 Truffle - Wikipedia, the free encyclopedia
Truffles are found anywhere from 2 to 16 inches below the ground, usually in a circular formation about 4 to 5 feet from the base of an oak tree.
The ascoma (fruiting body) of truffles is highly prized as food.
In 1825 Brillat-Savarin called the truffle "the diamond of the kitchen" and praised its aphrodisiac powers.

Ascomata may possess a preformed, apical opening (ostiole) for spore dispersal (perithecioid ascoma) or may be entirely closed, opening by weathering or wall disintegration (cleistothecioid ascoma).
The development of the centrum (structures within the ascoma, i.e., asci and surrounding sterile elements) has been an important character at the ordinal level.
The Sordariales is characterized by a certain centrum type consisting of pseudoparenchyma giving way to true paraphyses and asci produced in a basal layer even though the development of the centrum has been described for very few taxa in the group.

The ascoma can have three types: apothecium (ascoma half open), perithecium (ascoma partly open), and cleistothecium (ascoma closed).
Inside the ascoma is the hymenium which is furtil tissue.
The ascoma undergoes karyogamy to produce a diploid ascus that then undergoes meiosis.

Fossils of these early ascomycetes are not going to be easy to recognize, because they probably lacked ascoma and their spores were not distinctive.
The dikaryotic hyphae may be protected and nourished by differentiated haploid hyphae which form a fruiting body (the ascoma; plural ascomata).
Ascospores are released from the ascoma and germinate to form a new haploid mycelium.

Usually there are eight ascospores formed in each ascus, but the number can vary from one to more than one hundred, depending upon the species.
In most ascomycetes the asci are produced in or on a structure composed of fungal tissue that is called an ascoma or ascocarp.
They are divided into subgroups on the basis of the type of ascoma formed.
