Ascomycota is a phylum of the kingdom Fungi that, together with the Basidiomycota, forms the subkingdom Dikarya. Its members are commonly known as the sac fungi or ascomycetes . It is the largest phylum of Fungi, with over 64,000 species . [ 3 ]
Dothideomycetes is the largest and most diverse class of ascomycete fungi.It comprises 11 orders 90 families, 1,300 genera and over 19,000 known species. [1] [2] Wijayawardene et al. in 2020 added more orders to the class.
Sordariomycetes is a class of fungi in the subdivision Pezizomycotina (). [1] It is the second-largest class of Ascomycota, with a worldwide distribution that mostly accommodates terrestrial based taxa, although several can also be found in aquatic habitats. [2]
Ascomycota life cycle and morphology The phylum Ascomycota , or sac fungus , is characterized by formation of meiotic spores called ascospores enclosed in a special sac called an ascus . The genetic components for sexual reproduction appear to be produced by all members of this group.
The form of the ascus, the capsule which contains the sexual spores, is important for classification of the Ascomycota. There are four basic types of ascus. There are four basic types of ascus. A unitunicate-operculate ascus has a "lid", the Operculum , which breaks open when the spores are mature and allows the spores to escape.
Some of them, however, are known to have a teleomorph (sexual state) in the Ascomycota. With DNA evidence, all members of the genus Aspergillus are members of the phylum Ascomycota. [citation needed] Members of the genus possess the ability to grow where a high osmotic pressure exists (high concentration of sugar, salt, etc.).
Most ascomycetes are filamentous fungi that produce septate hyphae and have characteristics sexual phase in which they produce sexual spores called ascospores. [1] Most entomopathogenic fungi in the Phylum Ascomycota infect and proliferate in the insect body in a parasitic phase before eventually killing the host.
Saccharomycetes belongs to the Ascomycota division of the kingdom Fungi. It is the only class in the subdivision Saccharomycotina, the budding yeasts. Saccharomycetes contains a single order, Saccharomycetales. Saccharomycetes are known for being able to comprise a monophyletic lineage with a single order of about 1,000 known species.
