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.
Many imperfect fungi (fungi whose sexual reproduction is unknown) belong here, especially the genus Oidium. Recent molecular data have revealed the existence of six main evolutionary lineages. Clade 1 consists of Erysiphe , Microsphaera , and Uncinula , all of which have an Oidium subgenus Pseudoidium mitosporic state.
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.
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.
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.
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 English word fungus is directly adopted from the Latin fungus (mushroom), used in the writings of Horace and Pliny. [10] This in turn is derived from the Greek word sphongos (σφόγγος 'sponge'), which refers to the macroscopic structures and morphology of mushrooms and molds; [11] the root is also used in other languages, such as the German Schwamm ('sponge') and Schimmel ('mold').
