As further research continues, their position within the evolutionary tree can change. The mycelial plant body may be aseptate i. Characteristics of Division Eumycota 3. The subdivisions Mastigomycotina and Zygomycotina of G. Members are unicellular or filamentous with definite cell wall. Septate typically only form to delineate reproductive structures or to isolate damaged portions of mycelium.
Many genera of the class exhibit genetic variation as a result of heterokaryosis and parasexuality. Ascospores are produced in ascus Fig.
The bracket fungi like Polyporus betulinus, P. During cell division a short backwardly directed outgrowth develops from lateral wall, known as clamp. BotanyFungiClassificationDivision Eumycota. DeuteromycotaDeuteromycotinaFungi imperfectisubdivision Deuteromycotasubdivision Deuteromycotina – large and heterogeneous form division of fungi comprising forms for which no sexually reproductive stage is known. Different species of Pythium cause foot rot, fruit rot, rhizome rot and damping off detail in Table 4.
The most important and interesting members are the yeasts used in bakery and alcohol industry. Simultaneously, both the nuclei of ascus mother cell fuse and form diploid nucleus Fig. The pores are of different types: The diploid nucleus undergoes first meiotic division followed by single mitotic division, results in the formation of eight nuclei Fig. Motile cell zoospores present, perfect state spores typically oospores…. Later, it was also isolated from P. The ascocarps may be cleistothecium Penicilliumapothecium Ascobolusperithecium Daldenia or ascostroma Elsinoe veneta.
The product of sexual fusion may be zygote Synchytrium, Allomyceszygospore Rhizopus, Mucor or oospore Pythium, Phytophthorausually secretes a thick wall around itself and undergoes rest. Several members are able to control nematode diseases-by trapping the nematodes with their sticky mycelium or loops eu,ycota which nematodes adhere or trap and then the other hyphae invade and digest them.
They are also useful in many respects. The evolutionary tree shown is not complete it only shows the main divisions of the fungi kingdom and the family’s that I have photos for. Some divisipn them are terrestrial and parasitic. It has the spore bearing structure, called basidium.
The apical cell of ascogenous filament bends and may fuse with the basal cell and the region extends again and forms new binucleate penultimate cell as before Fig. The remaining two marked as solid nuclei in the cell are distributed towards apical and basal region. Different species of Albugo cause white rust disease of different hosts like crucifers cabbage, Brassica, radish, rurnip etc.
In this article we will discuss about: Coelomomyces anophelescia is an endoparasite on mosquito larvae and can be utilized for the biological control of Anopheles mosquito. Fungifungus kingdomkingdom Fungi – the taxonomic kingdom including yeast, molds, smuts, mushrooms, and toadstools; distinct from the green plants. The secondary mycelia may organise and form fruit body, called tertiary mycelium.
In other ways, due to lack of knowledge on sexual reproduction they could not be placed in the well-defined groups such as Mastigomycotina, Zygomycotina, Ascomycotina or Basidiomycotina and have been placed in a separate group, Deuteromycotina.
Important parasitic members are Synchytrium endobioticum causes wart disease of potato; Olpidium brassicae, in roots of Crucifers; Urophlyctis alfalfae causes crown wart of alfalfa Medicago ; and Physoderma maydis causes brown spot of maize. This process repeats several times and thus the growth continues. Are the only class of fungi whose mycelium is normally aseptate. Ainsworth classified the subdivision Deuteromycotina in three distinct classes; Blastomycetes, Hyphomycetes and Coelomycetes.
In some cases, mitotic division does not take place after meiosis and forms four ascospores Saccharomyces cerevisiae, Saccharomycodes ludwigii in an ascus. In unitunicate asci Peziza, Ascobolus etc.
Except in lower forms Puccinia, Ustilagosecondary mycelia by aggregation form fruit body, called basidiocarp Agaricus, Polyporus etc. This is a question and answer duvision for students, teachers and general visitors for exchanging articles, answers and notes. This page only shows some of the major fungi groups. The cells are haploid, dikaryotic or diploid. The mycelial cells may contain one nucleus, called monokaryotic i.
Switch to new thesaurus. Division may take place both in nucleus and cytoplasm of an ascus results in the formation of 2-celled ascospore.

BasidiomycotaBasidiomycotinasubdivision Basidiomycotasubdivision Basidiomycotina – comprises fungi bearing the spores on a basidium; includes Gasteromycetes puffballs and Tiliomycetes comprising the orders Ustilaginales smuts and Uredinales rusts and Hymenomycetes mushrooms, toadstools, agarics and bracket fungi ; in some classification systems considered a division of kingdom Fungi.
This process may repeat several times and a cluster of asci may develop. The asci become naked Fig.
