The Specific Mold and where it is found



ALTERNARIA (Air-borne) Colonies: grey, dark green, brown to black.  This is an outdoor mold, which frequently grows in textiles, foodstuffs, and soils.  The black spots seen on tomatoes are usually of the alternaria mold specie.  Frequently found on condensed window frames; generally an outdoors mold and appears when the weather is warm.  

ASPERGILLUS  This mold is found in damp conditions where the temperature is approximately 40 degrees Celsius, both indoor and outdoor.  Optimum growth requirements include a high water activity of the substrate, which is more likely to occur during the winter months.  Some diseases associated with the aspergillus are farmers lung, bakers asthma, and malt workers lung.  Inhalation of conidia and mycelium of aspergillus can lead to several diseases, the severity of which depends on the host's immune response.  It is found in soils, leaf, and plant litter, decaying vegetable and roots, bird droppings, tobacco, and stored sweet potatoes.  

BOTRYTIS    This worldwide mold predominantly occurs in humid and sub‑tropical regions.  The conidiophores of the mold usually cover the decayed tissues. It is seen as the grey mold on cabbage, red clover, lettuce, sugar beet, beans, barley, wheat, onion, and tomato. It is especially seen in connection with soft fruits, e.g., Strawberries and grapes.  In the wine industry, the growth of botrytis on wine grapes has been known to give an added effect to the bouquet of certain wines.  

CEPHALOSPORIUM   It is a mold found in decomposing vegetation, and it is a soil inhabitant. It is also found in dust from textile plants, soil when gardening, bathrooms, and damp old houses.  A grey/green colour, it is also occasionally found in patients sensitive to candida albicans.  


CLADOSPORIUM   Of all the molds encountered in the air, this is the most frequent. It is found most commonly on dying and dead plant substrates, especially on leaves and stems of ferns, mosses, and desert and aquatic plants.  It is found in various soil types and on food items such as cereals, cucumbers, tomatoes, and peaches.  It is also been found in fuel tanks, face creams, paints and textiles.  A moist, low damp environment is most suitable for the cladosporium mold (low dense and olive-green to olive-brown in colour).  Found throughout the year and indoors.  

CURVULARIA  This mold is dark brown in colour with a velvety appearance.  It can be found in   castor beans, cotton, rice, barley, wheat, and corn.  It seems to strive well in most tropical countries.  It may cause leaf spots and seeding blight.  

EPICOCCUM NIGRUM    This mold has worldwide distribution.  Found on soil, decaying plants, and fabrics.  It has also been isolated from cereals, fruits, polluted fresh water, compost beds, insects, human skin, and sputum. Quite a lot of airborne spores. Some Italian allergists rate it quite highly.  

FUSARIUM    This mold is common soil fungus and is widely found on numerous grasses and other plants.  It can cause plant diseases and is a major parasite of rice, sugar cane, sorghum, and especially maize grains.  Occurs regularly on banana roots and other fruits and vegetable, e.g., tomato and watermelon.  Sporulates in warm, wet weather.  Shares some of the same allergenic determinants as Penicillium and Aspergillus.  

HELMINTHOSPORIUM    This mold occurs seasonally and spores are released on dry, hot days.  It is a parasite of cereals and grasses.  Frequently found on grains, grasses, sugar cane, soil, and textiles.  



MUCOR RACEMOSUS   This mold has worldwide distribution and is primarily a soil fungus but has been found in horse manure, plant remains, grains, vegetables, and nuts.  In the tropics it is found at higher altitudes and often seen on soft fruit, fruit juice and marmalade.  Mucor is also the dominating mold found in floor dust in houses.  

PENICILLIUM    This mold also has a velvety colony, which has blue green centres with pale to bright yellow, vinaceous reverse and yellow exudate. It has a fruity odour, suggesting apples or pineapples.  It is found in the soil of citrus plantations and has been isolated from decaying cabbage and barley plants, stored seeds of cereals, grapes, nuts, dried fruits, and fruit juices.  It is one of the most dominant and important house molds; the indoor mold can be readily seen on stale bread, citrus fruits, and apples.  It is frequently found in wine cellars.  

RHODOTORULA Rubra   A marginally fermentable red yeast (a group as large as the white yeasts although less well known).  Very common on decaying foods.  May occur in the gut.  Found in pollen counts

SPOROBOLOMYCES   This is a yeast like fungus, which is found on living or dead leaves.  It is a pink to red colour mold. It is usually an airborne mold released during warm, damp weather, especially in the mornings, and can reach extremely high airborne concentrations.  

PHOMA HERBARUM    This mold is commonly found in different soils, dead plant tissues, and potatoes.  It grows indoors in association with bio‑deterioration of wall paints, and produces pink or purple colour spots.  This mold has also been isolated from moldy shower curtains.  

PULLULARIA    This mold is commonly found on dead and decaying leaves, wooden frames, saunas, refrigerator doors, and in the kitchen and bathroom.  It is grey in color and has been recorded on wheat seeds, barley, oats, tomato and pecans.
