The Importance of Fungi - ScienceAid.
Despite the mixed associations, almost 75 percent of fungi are classified under a single phylum called Ascomycota. Ascomycota are fungi that contain a sac that holds spores during the sexual stage.
The Ascomycota is the largest and most diverse group of extant fungi. The principal character of the group is the ascus, a sac-like structure where ascospores are produced. Compelling fossil evidence for the group extends back to the Early Devonian, although molecular clock evidence suggests they may extend back to the Precambrian.

The class zygomycetes derives its name from the thick-walled resting spores, the zygospores formed as a result of the complete fusion of the protoplasts of two equal or unequal gametangia. It comprises 450 species which are grouped under 70 genera. They all are terrestrial molds which show a wide range in their habit. Most of them are saprobes.
Ascomycota: The Sac Fungi The majority of known fungi belong to the Phylum Ascomycota, which is characterized by the formation of an ascus(plural, asci), a sac-like structure that contains haploid ascospores. Many ascomycetes are of commercial importance.

One of the largest classifications of fungi, there are over 50,000 species about 25,000 that only occur in lichens, ascomycota account for about 75% of all fungi. If you've ever seen the light green or grey splotchy mold on tree trunks, this is a type of ascomycota.
Members of the Ascomycota are widespread in distribution and can be found in almost all types of habitats. Many are of considerable economic importance, as food, in industrial processes, and as causes of various diseases in plants and animals. Characteristics of the ascomycetes: 1. sexual spores (meiospore n)-ascospores that develop in an ascus; forcibly discharged 2. ascus develops from a.
Scientific classification; Kingdom: Fungi. Subkingdom: Dikarya. Phylum: Ascomycota (Berk 1857) Caval.-Sm. 1998. Ascomycota is a phylum of fungi (kingdom Fungi), members are commonly known as the Sac Fungi, characterized by a saclike structure, the ascus, which contains four to eight ascospores in the sexual stage.

Introduction The phylum Ascomycota (colloquially called ascomycetes) is by far the largest group of fungi, estimated to include more than 32 000 described species in 3400 genera (Kirk et al., 2001).
The Ascomycota are morphologically diverse. The group includes organisms from unicellular yeasts to complex cup fungi. There are 2000 identified genera and 30,000 species of Ascomycota. The unifying characteristic among these diverse groups is the presence of a reproductive structure known as the ascus, though in some cases it has a reduced role in the life cycle. As a group, they are.

Ascomycota are heterotrophs and get their nutrients from dead or living organisms even jet fuel or wall paint. There are some forms of Ascomycota that produce asexually like Candida Albicans, causing vaginitis in women and Aspergillus flavus, a contaminant of nuts, which is a known carcinogen. Some other commonly known Ascomycota are black truffles and even some edible mushrooms. The yeast.

Classification of fungi is done so that fungi with similar characteristics and structures can be grouped together and thus making identification easier. Fungi are classified on the basis of their ability to reproduce sexually, asexually, or both. Ascospores, basidiospores, oospores, and zygospores, as well as any specialized structures associated with their development, are the basis of sexual.
