Mushrooms are mushroom forms. It is distinguished from its closely related counterpart, mold (English English: mold), mostly by its color: the mold appears in shades of black, blue, red, and green, while the fungus is white. It appears as a shallow, thin growth consisting of minute hyphae (filamentous filaments) produced primarily in living plants or organic materials such as wood, paper or leather. Both mushrooms and fungi produce different offensive odors, and both have been identified as the cause of certain human diseases.
In horticulture, the fungus is one of the fungi species in the order of Erysiphales, or fungal-like organisms in the family of Peronosporaceae . It is also used more generally to mean mushroom growth. In Old English, mushrooms mean melons (substances secreted by aphids in leaves, previously thought to be distilling from the air like dew), and then into mushrooms or fungi.

Patogen tanaman
What horticulturists and gardeners say as mushrooms is more appropriate powdery mildew. This is due to many different fungal species in the order of Erysiphales . Most species are specific for a narrow host range, and they are all mandatory parasites for flowering plants. The species that affect the roses are Sphaerotheca pannosa var. rosae .
Another type of fungus associated with plants is the diseases of stink, which are caused by fungal-like organisms in the family Peronosporaceae ( Oomycota ). They are mandatory plant pathogens, and many species are each parasite in a narrow host range. In agriculture, hairy mildews are a particular problem for potato farmers, grapes, tobacco and cucurbits.

The term moss is often used generally to refer to the growth of fungi, usually with a flat growth habit. Mushrooms can develop in many organic materials, including clothing, leather, paper, and ceilings, walls and floors of homes or offices with poor humidity control. The fungus can be cleaned by using a special mushroom remover, or a bleach-like substance (although they can blacken the surface).
There are many types of mushrooms. Black molds that grow in the attic, on window sills, and elsewhere where moderate moisture levels are often are Cladosporium . Color alone is not always a reliable indicator of fungal species. Proper identification requires a microbiologist or mycologist. Mushroom growth is found on cellulose-based substrates or ingredients where high humidity levels (90 percent or more) are often Stachybotrys chartarum. "Black prints," also known as "poisonous black fungus," refer to S. chartarum . This species is commonly found indoors on wet materials containing cellulose, such as wallboard (drywall), hemp, wicker, basket of straw, and other paper materials. S. chartarum does not grow in plastics, vinyl, concrete, glass, ceramic tiles, or metal. Other types of fungi, such as Penicillium or Aspergillus , may appear to grow on non-cellulose surfaces but actually grow on bio-films attached to these surfaces.. Glass, plastics, and concrete do not provide food for organic growth and therefore can not support the growth of mold or mildew without the presence of bio-film. In places with stagnant air, such as dungeons, the fungus can produce a strong musty smell.
Fungi require certain factors to be developed. Without one of these, it can not reproduce and grow. The requirements are food sources (any organic matter), adequate air humidity (relative humidity between 62 and 93 percent), and reasonable warmth (77 ° F (25 ° C) to 88 ° F (31 ° C C) is optimal, but some grown can occur anywhere between freezing and 95 ° F (35 ° C)). Slightly acidic conditions are also preferred. At warmer temperatures, the air is able to withstand larger volumes of water; when the air temperature drops, so does the air's ability to withstand the moisture, which then tends to condense on a cold surface. It can work to bring moisture to the surface where the fungus then tends to grow (like an outer wall). Preventing fungal growth requires a balance between moisture and temperature both in such a way that minimal humidity is available in the air and the air temperature is low enough to inhibit growth (at or below 70 ° F (21 ° C) without causing condensation occurs, or in such a way that warmer air temperatures, with no apparent changes in the amount of water vapor in the air, are by nature "drier" (have lower relative humidity) of colder air and will tend to inhibit mold growth in this way.Warmer temperatures coupled with high relative humidity set the stage for mold growth.
AC is one of the most effective tools to remove moisture and heat from warm moist air. The AC scrolls cause water vapor in the air to condense on them, eventually losing this excess moisture through the drain and putting it back into the environment. They can also inhibit the growth of fungus by lowering the temperature in the room. In order for them to be effective, the air conditioner must recirculate the air in the existing room and not exposed to warm and moist humid air. Some energy-efficient air conditioners can cool the room very quickly so they do not have the opportunity to effectively collect and deplete significant ambient water vapor.
