The life cycle of the Endogonales is distinguished by their production of small sporocarps containing many zygospores, which are eaten by rodents and distributed by their faeces. They also produce a fetid odour that attracts mammals and encourages them to eat their fruiting bodies, and so spread their spores.
Fungi that are not known to produce a teleomorph were historically placed into an artificial phylum, the "Deuteromycota," also known as "fungi imperfecti," simply for convenience. Some workers hold that this is an obsolete concept, and that molecular phylogeny allows accurate placement of species which are known from only part of their life ...
After two weeks of being infected by the fungus, the plant no longer generates the sugary liquid, and the fungus produces sclerotia. The sclerotium is an overwinter structure, which contains ergot alkaloids. Claviceps purpurea ' s life cycle is an interesting model for plant pathologists and cell biologists because: [4] Strict organ specificity ...
The fungus kingdom encompasses an enormous diversity of taxa with varied ecologies, life cycle strategies, and morphologies ranging from unicellular aquatic chytrids to large mushrooms. However, little is known of the true biodiversity of the fungus kingdom, which has been estimated at 2.2 million to 3.8 million species. [ 7 ]
Some time after the Permian-Triassic extinction event (251.4 Ma), a fungal spike (originally thought to be an extraordinary abundance of fungal spores in sediments) formed, suggesting that fungi were the dominant life form at this time, representing nearly 100% of the available fossil record for this period.

This stage of the life cycle, along with its preference for damp shady habitats, likely contributed to the original mischaracterization of the organism as a fungus. P. polycephalum is used as a model organism for research into motility, cellular differentiation, chemotaxis, cellular compatibility, and the cell cycle. It is commonly cultivated.
Neurospora crassa life cycle. The haploid mycelium reproduces asexually by two processes: (1) simple proliferation of existing mycelium, and (2) formation of conidia (macro- and micro-) which can be dispersed and then germinate to produce new mycelium.
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. [6]
