Which is correct group for deuteromycetes?
Which is correct group for deuteromycetes?
Despite its “-mycetes” ending the deuteromycetes are not a class; rather this term is now used as a common name for this dumping-ground group of fungi. About 90% of these have affinities to the Ascomycota. Most food spoilage (Figures 9 and 10) and fungal human diseases are caused by members of this group.
What are the major groups of fungi?
Fungi are usually classified in four divisions: the Chytridiomycota (chytrids), Zygomycota (bread molds), Ascomycota (yeasts and sac fungi), and the Basidiomycota (club fungi). Placement into a division is based on the way in which the fungus reproduces sexually.
Why are the deuteromycetes considered an artificial group?
Deuteromycota is referred to as form-phylum because the divisions within the group are based on morphology and not on common phylogenetic background. It is thus considered an artificial grouping.
Is Aspergillus a deuteromycetes?
Other, more informal names besides Deuteromycota (“Deuteromycetes”) and fungi imperfecti are anamorphic fungi, or mitosporic fungi, but these are terms without taxonomic rank….

Is Penicillium a Deuteromycota?
Asexual Ascomycota, such as Penicillium or Candida species, used to be classified separately in the Deuteromycota because sexual characters were necessary for Ascomycota classification.
How do you identify Deuteromycota?
Key Points
- Deuteromycota do not possess the sexual structures that are used to classify other fungi.
- Most deuteromycota live on land; they form visible mycelia with a fuzzy appearance called mold.
- Recombination of genetic material is known to take place between the different nuclei after some hyphae recombine.
What are the characteristics of deuteromycetes?
The Deuteromycetes classification is characterized by the absence of teleomorphic (meiotic) states. It is heterogeneous, i.e., polyphyletic. Reproduction occurs commonly by spores (conidia) produced mitotically (asexually) from conidiogenous cells.
What are the six groups of fungi?
Terms in this set (6)
- Microsporidia. -unicellular, obligate, intracellular parasites of animals.
- Chytrids. -only fungi with flagella at any life stage.
- Zygospore Fungi. -terrestrial fungi.
- Arbuscular Mycorrhizal Fungi. -have symbiotic, mutalistic relationship with over 80% of all plants.
- Sac fungi. -ascomycota.
- Club Fungi.
How many groups of fungi are there?
There are four major groups of fungi: Zygomycota, Ascomycota (sac fungi), Basidiomycota (club fungi), and Deuteromycota (fungi imperfecti).
What are the general characteristics of deuteromycetes?
Is Trichoderma a imperfect fungi?
They are called as imperfect because sexual reproduction is absent in these forms. They reproduce only by asexual spores called conidia. They have septate and multinucleate mycelium. e.g., Alternaria, Trichoderma, Colletotrichum.
