Mucorales
The Mucorales is the largest and best studied order of zygomycete fungi. Members of this order are sometimes called pin molds. The term mucormycosis is now preferred for infections caused by molds belonging to the order Mucorales. Systematics The order includes: 11 families, 56 genera, and approximately 300 species. Mucoralean classification has traditionally been based on morphological, developmental, and ecological characteristics. Recently, molecular data has revealed, that some aspects of traditional classification are quite artificial. For example, the Mucoraceae is believed to be polyphyletic, as are the Thamnidiaceae, Chaetocladiaceae and Radiomycetaceae. Some of the genera, (including ''Mucor'', ''Absidia'' and ''Backusella'') appear to be polyphyletic. Today, the traditional system is still largely in use, as further studies are needed to reconcile morphological and molecular concepts of families and genera. Families The order consists of the following families ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zygomycete
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. Approximately 1060 species are known. They are mostly terrestrial in habitat, living in soil or on decaying plant or animal material. Some are parasites of plants, insects, and small animals, while others form symbiotic relationships with plants. Zygomycete hyphae may be coenocytic, forming septa only where gametes are formed or to wall off dead hyphae. Zygomycota is no longer recognised as it was not believed to be truly monophyletic. Etymology The name ''Zygomycota'' refers to the zygosporangia characteristically formed by the members of this clade, in which resistant spherical spores are formed during sexual reproduction. ''Zygos'' is Greek for "joining" or "a yoke", referring to the fusion of two hyphal strands which produces these spores, and ''-mycota'' is a suffix referring to a division of fungi. Spores Th ...

Backusella
''Backusella'' is the sole genus of zygote fungi in the family Backusellaceae, which is classified in the order Mucorales. Members of this genus have been often isolated from plant litter, from locations around the world. Taxonomy C. W. Hesseltine and J. J. Ellis recognised the uniqueness of a new species, ''B. circina'', warranted its classification in a new genus; in 1969 they established ''Backusella'', named in honour of Professor M. P. Backus. Since then, several species previously placed in the archetypal mucoralean genus ''Mucor'' were reassessed, found to be close relatives of ''B. circina'', and combined into ''Backusella'' as additional ''Backusella'' species, while other species were discovered and classified outright as ''Backusella''. K. Voigt & P.M. Kirk established the family Backusellaceae to include ''Backusella'' in 2012, as they likewise recognised the uniqueness of the genus and the need to classify it within a distinct family. Accepted species The genus co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Zygomycosis
Zygomycosis is the broadest term to refer to infections caused by ''bread mold fungi'' of the zygomycota phylum. However, because zygomycota has been identified as polyphyletic, and is not included in modern fungal classification systems, the diseases that zygomycosis can refer to are better called by their specific names: mucormycosis (after Mucorales), phycomycosis (after Phycomycetes) and basidiobolomycosis (after Basidiobolus). These rare yet serious and potentially life-threatening fungal infections usually affect the face or oropharyngeal (nose and mouth) cavity. Zygomycosis type infections are most often caused by common fungi found in soil and decaying vegetation. While most individuals are exposed to the fungi on a regular basis, those with immune disorders (immunocompromised) are more prone to fungal infection. These types of infections are also common after natural disasters, such as tornadoes or earthquakes, where people have open wounds that have become filled with s ...

Saksenaeaceae
The Saksenaeaceae are a family of fungi in the order Mucorales. It was circumscribed in 1974 by J.J. Ellis and Clifford Hesseltine. Description This family is characterized by having sporangia that are lageniform and columellate. Zygospore A zygospore is a diploid reproductive stage in the life cycle of many fungi and protists. Zygospores are created by the nuclear fusion of haploid cells. In fungi, zygospores are formed in zygosporangia after the fusion of specialized budding struc ...s are unknown.

Pilobolaceae
The ''Pilobolaceae'' are a family of fungi in the Mucorales order. Generally, species in this family have a widespread distribution, although there are some that are restricted to tropical and subtropical regions. This family includes two genera: ''Pilobolus'', and '' Utharomyces''.Alexopoulos C. J., C. W. Mims, & M. Blackwell. 1996. Introductory Mycology. Fourth Edition. John Wiley & Sons, Inc.Hesseltine C.

Morphology All species produce unusual, phototrophic sporangiophores. These sporangiophores give rise to dark-colored, columellate sporagia covered in calcium oxalate crystals. In ''Pilobolus'' and ''Utharomyces'', inflated structures filled with yellow cartenoid pigments give rise to the sporophores; these two genera also produce subsporangiul vesicles.

Cunninghamellaceae
The ''Cunninghamellaceae'' are a family of fungi in the order Mucorales. Taxonomy At one time, this family contained four genera.Hesseltine C. W. & J. J. Ellis. 1973. Mucorales. ''in'': The Fungi: An Advanced Treatise. Volume 5B. A Taxonomic Review with Keys: Basidiomycetes and Lower Fungi. Academic Press. New York. pg. 187-217.

Pilobolus Crystallinus
''Pilobolus crystallinus'' var. ''crystallinus'', commonly known as the "Dung Cannon" or "Hat Thrower", is a species of fungus belonging to the Mucorales order. It is unique in that it adheres its spores to vegetation, so as to be eaten by grazing animals. It then passes through the animals' digestive systems and grows in their feces. Although these fungi only grow to be tall, they can shoot their sporangium, containing their spores, up to away. Due to an increase of pressure in the vesicle, the sporangium can accelerate 0–45 mph in the first millimeter of its flight, which corresponds to an acceleration of an incredible 20000 g. Using a mucus-like substance found in the vesicle of the fungus, the sporangium can adhere itself onto whatever it lands, thus completing its life cycle. The basionym of this species is ''Hydrogera crystallina'' F.H. Wigg. 1780. The ability of this fungus to cause problems for florists was noted in the scientific literature in 1881: ... th ...
