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 cycle.
Protomyces macrosporus has a complex life cycle including ascospores and chlamydospores. [4] Spores reach the hosts via air movements and are spread from the galls that develop on the petioles, midrib veins, and lamina; they will only germinate on the correct host.
The life cycle of the subdivision is dimorphic and it consists of two phases in the life cycle. One saprobic haploid phase and a parasitic ( biotrophic ) dikaryotic phase. The saprobic phase is initiated by the production of haploid yeasts, which fuses with another spore and produce the n+n hyphae which will infect the host.
Neurospora is a genus of Ascomycete fungi. The genus name, meaning "nerve spore" refers to the characteristic striations on the spores that resemble axons . The best known species in this genus is Neurospora crassa , a common model organism in biology .
Rust fungi are often categorized by their life cycle. Three basic types of life cycles are recognized based on the number of spore types as macrocyclic, demicyclic, and microcyclic. [3] The macrocyclic life cycle has all spore states, the demicyclic lacks the uredinial state, and the microcyclic cycle lacks the basidial, pycnial, and the aecial ...
The heterothallic life cycle of N. crassa is given in some detail, since similar life cycles are present in other heterothallic fungi. Certain heterothallic species (such as Neurospora tetrasperma) are called "pseudo-homothallic". Instead of separating into four individual spores by two meiosis events, only a single meiosis occurs, resulting in ...
In some higher fungi such as ergot, sclerotia become detached and remain dormant until favorable growth conditions return. Sclerotia initially were mistaken for individual organisms and described as separate species until Louis René Tulasne proved in 1853 that sclerotia are only a stage in the life cycle of some fungi.

Zygomycota, or zygote fungi, is a former division or phylum of the kingdom Fungi. The members are now part of two phyla: the Mucoromycota and Zoopagomycota. [1] Approximately 1060 species are known. [2] They are mostly terrestrial in habitat, living in soil or on decaying plant or animal material.
