Molds are considered to be microbes and do not form a specific taxonomic or phylogenetic grouping, but can be found in the divisions Zygomycota and Ascomycota. In the past, most molds were classified within the Deuteromycota. [5] Mold had been used as a common name for now non-fungal groups such as water molds or slime molds that were once ...
The spores are wind-dispersed and they are often extremely abundant in outdoor air. Indoors Cladosporium species may grow on surfaces when moisture is present. Cladosporium fulvum, cause of tomato leaf mould, has been an important genetic model, in that the genetics of host resistance are understood. [4]
Cladosporium cladosporioides occurs outdoor environments year-round with peak spore concentration in the air occurring in summer where levels can range from 2,000 spores up to 50,000 spores per cubic meter of air. [16] It is among the most common of all outdoor airborne fungi, [16] colonizing plant materials and soil. [14]
Spores need three things to grow into mold: nutrients – cellulose (the cell wall of green plants) is a common food for indoor spores; moisture – to begin the decaying process caused by mold; and time – mold growth begins from 24 hours to 10 days after the provision of growing conditions. Mold colonies can grow inside buildings, and the ...
Mold is a dangerous library pest because of the damage it causes to the collections. Mold thrives off of paper and books; these objects provide the fungi a source of nutrition, namely the sugar and starches present in the cellulose materials. [6] Mold feeds on cloth, leather, glues, adhesives, cellulose starch and starches in the sizing.

Unidentified water mold on dead larval mayfly. A culture of Achlya sp. (Saprolegniales) isolated from a stream. Sea trout suffering from UDN with secondary Saprolegnia infections. Many oomycetes species are economically important, aggressive algae and plant pathogens. [12] [13] Some species can cause disease in fish, and at least one is a ...
