Achlya is a genus of oomycete (water mold), in the family Saprolegniaceae.The genus includes several plant pathogens including Achlya conspicua and Achlya klebsiana.Unlike many other microorganisms, cell expansion is governed by changes in cell wall strength rather than changes in osmotic pressure. [1]
While it is found most frequently in freshwater, it will also tolerate brackish water and even moist soil. Saprolegnia filaments are long with rounded ends, containing the zoospores. Saprolegnia generally travels in colonies consisting of one or more species. They first form a mass of individual hyphae.
'fungus'), referring to the large round oogonia, structures containing the female gametes, that are characteristic of the oomycetes. The name "water mold" refers to their earlier classification as fungi and their preference for conditions of high humidity and running surface water, which is characteristic for the basal taxa of the oomycetes.
The most infamous species, Stachybotrys chartarum (previously known as Stachybotrys atra) and Stachybotrys chlorohalonata, are known as black mold or toxic black mold in the U.S., and are frequently associated with poor indoor air quality that arises after fungal growth on water-damaged building materials.

Close up of mold on a strawberry Penicillium mold growing on a clementine. A mold (US, PH) or mould (UK, CW) is one of the structures that certain fungi can form. The dust-like, colored appearance of molds is due to the formation of spores containing fungal secondary metabolites. The spores are the dispersal units of the fungi.
Geotrichum is a genus of fungi found worldwide in soil, water, air, and sewage, as well as in plants, cereals, and dairy products; it is also commonly found in normal human flora and is isolated from sputum and feces. It was first described in 1809 by Johann Heinrich Friedrich Link. [1] The genus Geotrichum includes over 100 species. Some are ...

Physarum polycephalum, an acellular [1] slime mold or myxomycete popularly known as "the blob", [2] is a protist with diverse cellular forms and broad geographic distribution. The “acellular” moniker derives from the plasmodial stage of the life cycle : the plasmodium is a bright yellow macroscopic multinucleate coenocyte shaped in a ...
