Sexual Reproduction
Sexual reproduction is known to occur in all groups of fungi except the Fungi imperfecti or Dueteromycetes . It may involve fusion of gametes, gametangia or hyphae. The process may involve only fusion of cytoplasm ( plasmogamy ) or fusion of nuclei ( karyogamy ) or production of meiotic s..
Kingdom Mycota or Fungi
). Many members of fungi are parasitic on plants and animals including humans. Some fungi grow on dung (coprophilous) while a few others are found in symbiotic association with other organisms. The body of a fungus can be described as a thallus since it is not differentiated into root system and le..

Based on the compatibility in sexual reproduction the fungal hyphae can be distinguished into two types homothallic and heterothallic . In homothallic forms, fusion occurs between the genetically similar strains or mating types . In such forms, meiosis results in the formation o..
Summary
>Fungi are a group of heterotrophic (saprotrophic or parasitic) primitive eukaryotes. Fungal plant body is called mycelium. It may be unicellular and multicellular. The multicellular mycelium forms filamentous structures called hyphae. Fungi reproduce by fission, budding and sexual m..
Vegetative Reproduction
It is the type of reproduction which involves the somatic portion of the fungal thallus. It occurs by the following metho..
Vesicular Arbuscular Mycorrhizae (VAM)
Mycorrhizae is a type of fungus living in association with plant roots. Hyphae of such fungi are found in between cortical cells of roots and protrude outside the roots also. The Mycorrhizae lives in close association with roots without disturbing their normal physiology. These hyph..
Oidia
These are spore like structures formed by the breaking up of hypha cells. They do not store reserve food and hence cannot survive under unfavourable conditions. Such spores are produced in Rhizopu..
Somatogamy
In examples like Agaricus, fusion occurs between two somatic cells and involves only plasmogamy. This results in the formation of dikaryotic hyphae. Hence, the process is called dikaryotizatio..
