Dark Green Mold

Class Fungi Imperfecti Order Moniliales Family Dematicaeae Common Name The Dark Green Mold. Greek Root From klados which means branched and sporium or spore. The name is in reference to the two celled spores produced on branches from the main body of the conidiophore. 

Measures of Control Good hygienic practices removal of supportive substrates and filtration of air through micron filters. 

Macroscopic Appearance Species of Cladosporium causing problems in spawn production are typically dark green in color, often becoming blackish with age, and resemble the powdery Penicillium type molds. 

History, Use and/or Medical Implications Some species toxic. Cladosporium carrionii causes a severe skin infection that is usually associated with workers who suffer punctures from thorns or splinters. 

Comments In one study (Kramer, 1959) where agar plates were exposed daily to the outside air over a period of two years, Cladosporium spores were found to be the most numerically common of all airborne fungi, representing 45% of the totals tallied. Of these species, C. cladosporioides was the most frequently encountered. In contrast, Penidllium is the most common fungus indoors, undoubtedly due to the food habits of humans.

In your bathroom, the most common mildew is Cladosporium, a speckled black or dark green mold that sometimes appears around the tub. It s different from the highly toxic "black mold" that haunts every homeowner s nightmares, but you ll still want to remove it. 

Polymerization is usually carried out by heating in an open aluminum mold in an air-circulating oven. The crystalline monomer melts and, over a period of days, forms a dark green "B-staged" resin, which eventually solidifies into a rubber and finally a glass. 

Macroscopic Appearance Mycelia inconspicuous at first, grayish and in some species whitish, cottony, dense and aerial (as in "White Chaetomium"). Some forms become light brown, yellowish or with orangish hues when well developed. At maturity these molds can become dark green to olive green colored, and form scattered "burrs" which in fact are perithecia containing spores.
