Mold has attacked this home.

Ascospores are prominent in nature commonly found in the outdoor environment. Some fungi that belong to the Ascomycete family include the sexual forms of Penicillium/Aspergillus, Chaetominum, etc that may be frequently found growing on damp substrates.

Chaetomium are found on a variety of substrates containing cellulose including paper and plant compost. Several species have been reported to play a major role in the decomposition of cellulose-made materials. These fungi are able to dissolve the cellulose fibers in cotton and paper and thus cause the materials to disintegrate. The process is especially rapid under moist conditions. Their Ascospores are brown or gray with one or two germ pores.

Fusarium is a hydrophilic mold that requires very wet conditions and is frequently isolated from plants and grains. They colonize in continuously damp materials such as damp wallboard and water reservoirs for humidifiers and drip pans. Fusarium is commonly found in organic matter such as soil and plants. This infection cannot be transmitted from person to person. 

Aspergillus and Penecillium are both types of mold are ubiquitous in the environment. Aspergillus tends to colonize continuously damp materials such as damp wallboard and fabrics. Penicillium is commonly found in house dust, wallpaper, decaying fabrics, moist clipboards, etc.

Stachybotrys is the bad boy of them all

Stachybotrys, commonly called "stachy," is a greenish-black, slimy mold found only on cellulose products (such as wood or paper) that have been wet for several days or more. The mold does not grow on concrete, linoleum or tile. Stachybotrys and some other fungi may produce several chemicals called mycotoxins. Mycotoxins can be present in spores and small mold fragments released into the air. Once the mold fragments, mycotoxins and spores are in the air, individuals may breathe them into their lungs.
