Deuteromycota: The Imperfect Fungi by Aigali Nargiza on Prezi.

Classification of Fungi. The kingdom Fungi contains five major phyla that were established according to their mode of sexual reproduction or using molecular data. Polyphyletic, unrelated fungi that reproduce without a sexual cycle, are placed for convenience in a sixth group called a “form phylum.”. Deuteromycota is a polyphyletic group.

Conidial stages are similar to those in the phylum Ascomycota, but those of some species show affinities to lower (primitive) fungi and the phylum Basidiomycota. Because of this ambiguity, the term deuteromycetes is used only to describe some species of fungi and has very little importance in the classification of fungi.

Deuteromycota A taxon, usually given the rank of phylum, that is used in some classifications to include all fungi in which sexual reproduction is apparently absent.

Classification. Introduction to Zygomycetes: 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.

FUNGI IMPERFECTI (Deuteromycota) nonphylogenetic group of fungi without known sexual cycles or with unobserved sexual cycles. Unique Phylum 1. groupings may or may not represent phylogeny e.g., species in same genus may be less related than species in different genera 2.

In older classifications, chytrids, except the recently established order Spizellomycetales, were placed in the class Phycomycetes under the subphylum Myxomycophyta of the kingdom Fungi. Previously, they were placed in the Mastigomycotina as the class Chytridiomycetes.

Problems in taxonomic classification. Although the taxon Deuteromycota is no longer formally accepted, many of the fungi it included have yet to find a place in modern fungal classification. This is because most fungi are classified based on characteristics of the fruiting bodies and spores produced during sexual reproduction, but members of the Deuteromycota have only been observed to produce.

Those fungi that lack a known sexual reproduction cycle are in the division Deuteromycetes. As far as we know, these fungi reproduce only by an asexual process. (When such an organism’s sexual stage is discovered, the fungus is usually reclassified.). Quiz Basics of Classification Taxonomy Kingdoms of Living Things Quiz Domains and.

In this lesson, you'll delve into the world of Ascomycota fungi. You'll learn what the term 'ascomycota' means, understand how these creatures fit into the categorization of life on Earth, and see.

Traditionally, Deuteromycotina are separated into two classes: Hyphomycetes, which are mycelial forms bearing conidia on separate hyphae or aggregations of hyphae; and Coelomycetes, which are forms that produce conidia in pycnidial, pycnothyrial, acervular, cupulate, or stromatic conidiomata.

Thus, some fatty acids at specific concentrations have the potential to protect wood from wood-inhabiting fungi; however, conditions relating to efficacy of a given fatty acid against a wide variety of ascomycetes, deuteromycetes, and basidiomycetes remains to be identified.
