Exposure to mold may also cause heightened sensitivity depending on the time and nature of exposure.
Rhizoctonia solani root rot on corn roots, magnified 0.63X. Damping off can be prevented or controlled in several different ways. Sowing seeds in a sterilized growing medium can be effective, although fungal spores may still be introduced to the medium, either on the seeds themselves or after sowing (in water or on the wind).
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.
The term brown rot replaced the general use of the term dry rot, as wood must be damp to decay, although it may become dry later. Dry rot is a generic name for certain species of brown-rot fungi. Brown-rot fungi of particular economic importance include Serpula lacrymans (true dry rot), Fibroporia vaillantii (mine fungus), and Coniophora ...
Mold allergies are present in a minority of the population that is genetically predisposed to mold, and usually this allergy is not life threatening. Black molds, or so called toxic molds, can ...
Aspergillus niger is a prime example of this; it can be found growing on damp walls, as a major component of mildew. [citation needed] Several species of Aspergillus, including A. niger and A. fumigatus, will readily colonise buildings, [7] favouring warm and damp or humid areas such as bathrooms and around window frames.

Aspergillus versicolor is a highly ubiquitous species commonly isolated from soil, plant debris, marine environments, and indoor air environments. [5] [6] It is among the most common of indoor molds, often reported in dust and in water-damaged building materials, such as wallboards, insulation, textiles, ceiling tiles, and manufactured wood.
