Molds are considered to be microbes and do not form a specific taxonomic or phylogenetic grouping, but can be found in the divisions Zygomycota and Ascomycota. In the past, most molds were classified within the Deuteromycota. [5] Mold had been used as a common name for now non-fungal groups such as water molds or slime molds that were once ...
Unidentified water mold on dead larval mayfly. A culture of Achlya sp. (Saprolegniales) isolated from a stream. Sea trout suffering from UDN with secondary Saprolegnia infections. Many oomycetes species are economically important, aggressive algae and plant pathogens. [13] [14] Some species can cause disease in fish, and at least one is a ...
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').
If a house is artificially humidified, by the use of a humidifier, during the winter, this can create conditions favorable to mold. Moving air may prevent mold from growing, since it has the same desiccating effect as low humidity. Mold grows best in warm temperatures, 25 to 30 °C (77 to 86 °F), although growth may occur between 0 and 35 °C ...
When mold spores are inhaled by an immunocompromised individual, some mold spores may begin to grow on living tissue, [28] attaching to cells along the respiratory tract and causing further problems. [29] [30] Generally, when this occurs, the illness is an epiphenomenon and not the primary pathology. Also, mold may produce mycotoxins, either ...
The spores of rust fungi may be dispersed by wind, water or insect vectors. [13] When a spore encounters a susceptible plant, it can germinate and infect plant tissues. A rust spore typically germinates on a plant surface, growing a short hypha called a germ tube. This germ tube may locate a stoma by a touch responsive process known as ...
Slime molds contribute to the decomposition of dead vegetation; some are parasitic. Most slime molds are terrestrial and free-living, typically in damp shady habitats such as in or on the surface of rotting wood. Some myxogastrians and protostelians are aquatic or semi-aquatic. The phytomyxea are parasitic, living inside their plant hosts.
Factors that influence whether or not marine fungi are present in any particular location include the water temperature, its salinity, the water movement, the presence of suitable substrates for colonization, the presence of propagules in the water, interspecific competition, pollution and the oxygen content of the water.
