Aspergillus penicillioides is a species of fungus in the genus Aspergillus, and is among the most xerophilic fungi. [1]Aspergillus penicillioides is typically found in indoor air, house dust, and on substrates with low water activity, such as dried food, papers affected by foxing, and inorganic objects such as binocular lenses.

The Aspergillaceae are a family of fungi in the order Eurotiales which are commonly known as the blue and green molds. [4] [5] The family includes the commonly known and observed genera of Aspergillus [6] and Penicillium [7] amongst other lesser known mold genera but also includes larger ascomycete fungi such as Penicilliopsis.
Saprophytic species of Penicillium and Aspergillus are among the best-known representatives of the Eurotiales and live mainly on organic biodegradable substances. Commonly known in America as molds, they are among the main causes of food spoilage, especially species of subgenus Penicillium. [9] Many species produce highly toxic mycotoxins.
When first described, the family contained some of the most familiar fungi, such as Penicillium and Aspergillus.In 2011, it was proposed, that the family should be split into the three families Aspergillaceae, Thermoascaceae and Trichocomaceae.
Aspergillus species are highly aerobic and are found in almost all oxygen-rich environments, where they commonly grow as molds on the surface of a substrate, as a result of the high oxygen tension. Commonly, fungi grow on carbon-rich substrates like monosaccharides (such as glucose ) and polysaccharides (such as amylose ).

Penicillium spinulosum (spinulosus means with small spines in Latin) is a non-branched, fast-growing fungus with a swelling at the terminal of the stipe (vesiculate) in the genus Penicillium. [ 3 ] [ 4 ] P. spinulosum is able to grow and reproduce in environment with low temperature and low water availability, [ 5 ] and is known to be ...
Aspergillus restrictus is a species of fungus in the genus Aspergillus. It is from the Restricti section. [3] The species was first described in 1931. [1] It is xerophilic, frequently found in house dust. Studies have suggested that it is an allergen implicated in asthma.
