White mold (Sclerotinia) Kenneth B. Johnson, Oregon State University. Diseases caused by Sclerotinia spp., generally known as 'white mold', can affect hundreds of plant species including many important crops. The pathogens are favored by cool, moist conditions, but show surprisingly broad ecological distributions. 1 Several other Sclerotinia species cause diseases other than white mold.

Mold Currently there is no conclusive scientific evidence linking the inhalation of black mold spores or any type of mold in the indoor environment to any illness other than the previously described allergy symptoms. The term “toxic” is an inaccurate description of this mold.

Informing Tenants of Black Mold Protections Black mold is a fungus that releases toxic spoors into the air that can cause respiratory illness and irritation. The responsibility for a mold-free environment in a rental unit ultimately falls onto the landlord. Between letting tenants know about past mold history and ensuring that conditions are inhospitable for mold to grow, landlords must stay in communication with tenants about black mold protections.

Yeast A mold or mould is a fungus that grows in the form of multicellular filaments called hyphae. In contrast, fungi that can adopt a single-celled growth habit are called yeasts. Molds are a large and taxonomically diverse number of fungal species in which the growth of hyphae results in discoloration and a fuzzy appearance, especially on food. The network of these tubular branching hyphae, called a mycelium, is considered a single organism. The hyphae are generally transparent, so the mycelium appe

Black Mold - Stachybotrys Black Mold, also known as Stachybotrys Chartarum is a toxic greenish black fungus found worldwide that colonizes particularly well in high-cellulose material, such as straw, hay, wet leaves, dry wall, carpet, wall paper, fiber-board, ceiling tiles, thermal insulation, etc.ut not all black molds are toxic, and not all toxic molds are black. For example, the black slimy stuff that commonly grows on the grout in bathrooms is probably not the dreaded kind known as Stachybotrys (pronounced Stacky-Boatris), but you will want to test to be sure.

Deadly Molds Molds are a variety of spore-producing fungi that form in decaying food or in warm, moist places. These fungi usually have a woolly or furry texture. While most molds are harmless, there are at least three varieties of monstrous molds that pose a deadly threat to adventurers: brown, russet, and yellow mold. Brown Mold: Brown mold is found in damp subterranean areas, such as caverns and caves. It is light to golden brown in color.

Mold vs. Mildew But mold and mildew also have striking differences when it comes to size, color and texture. Mildew is a surface fungi that can easily be identified as a patch of gray or even white fungus that is lying on the surface of a moist area. Mildew is easily treated with a store bought cleaner and a scrubbing brush. Mold, on the other hand, can be black or green and is often the result of a much larger infestation. This type of fungus can appear almost fuzzy  especially when it is found on food  or even slimy in nature.

Historically, it was considered closely related to the genus Memnoniella, because the spores are produced in slimy heads rather than in dry chains.

White mold in the flower garden White mold is a disease that results in stem rot, wilt, and death of many common flowers. The fungal pathogen that causes white mold makes a hard resting structure that can survive in the garden for many years, allowing the disease to reoccur each year. As a result, early identification and removal of infected plants are critical steps in managing this disease. The fungus Sclerotinia sclerotiorum.

White-nose syndrome (WNS) is an emerging disease in North American bats which by 2012 was associated with at least 5.7 million bat deaths. The condition is named for a distinctive fungal growth around the muzzles and on the wings of hibernating bats and was first identified from a February 2006 photo taken in a cave in Schoharie County, New York.
